# Software Bill of Materials (SBOM)
PX4 generates a [Software Bill of Materials](https://ntia.gov/SBOM) for every firmware build in [SPDX 2.3](https://spdx.github.io/spdx-spec/v2.3/) JSON format.
## Why SBOM?
- **Regulatory compliance**: The EU Cyber Resilience Act (CRA) requires SBOMs for products with digital elements (reporting obligations begin in September 2026).
- **Supply chain transparency**: SBOMs enumerate every component compiled into firmware, enabling users and integrators to audit dependencies.
- **NTIA minimum elements**: Each SBOM satisfies all seven [NTIA required fields](https://www.ntia.gov/report/2021/minimum-elements-software-bill-materials-sbom): supplier, component name, version, unique identifier, dependency relationship, author, and timestamp.
## Format
PX4 uses SPDX 2.3 JSON.
SPDX is the Linux Foundation's own standard (ISO/IEC 5962), aligning with PX4's position as a Dronecode/LF project.
Zephyr RTOS also uses SPDX.
Each SBOM contains:
- **Primary package**: The PX4 firmware for a specific board target, marked with `primaryPackagePurpose: FIRMWARE`.
- **Git submodules**: All third-party libraries included via git submodules (~33 packages), with SPDX license identifiers and commit hashes.
- **Python build dependencies**: Packages from `Tools/setup/requirements.txt` marked as `BUILD_DEPENDENCY_OF` the firmware.
- **Board-specific modules**: Internal PX4 modules compiled for the target board.
- **Compiler**: The C compiler used for the build.
Typical SBOM size: 70-100 packages, ~500 lines, ~20 KB JSON.
## Generation
SBOMs are generated automatically as part of every CMake build.
The output file is:
```txt
build/<target>/<target>.sbom.spdx.json
```
例如:
```txt
build/px4_fmu-v6x_default/px4_fmu-v6x_default.sbom.spdx.json
```
The generator script is `Tools/ci/generate_sbom.py`.
It requires PyYAML (`pyyaml`) for loading license overrides.
### CMake Integration
The `sbom` CMake target is included in the default `ALL` target.
The relevant CMake module is `cmake/sbom.cmake`.
### Disabling SBOM Generation
Set the environment variable before building.
This is checked at CMake configure time, so a clean build or reconfigure is required:
```sh
PX4_SBOM_DISABLE=1 make px4_fmu-v6x_default
```
If the build directory already exists, force a reconfigure:
```sh
PX4_SBOM_DISABLE=1 cmake -B build/px4_fmu-v6x_default .
```
### Manual Generation
You can also run the generator directly:
```sh
python3 Tools/ci/generate_sbom.py \
--source-dir . \
--board px4_fmu-v6x_default \
--modules-file build/px4_fmu-v6x_default/config_module_list.txt \
--compiler arm-none-eabi-gcc \
--output build/px4_fmu-v6x_default/px4_fmu-v6x_default.sbom.spdx.json
```
## Artifacts
SBOMs are available in:
| Location | Path |
| --------------- | ---------------------------------------- |
| Build directory | `build/<target>/<target>.sbom.spdx.json` |
| GitHub Releases | Alongside `.px4` firmware files |
| S3 | Same directory as firmware artifacts |
## Validation
Validate an SBOM against the SPDX JSON schema:
```sh
python3 -c "
import json
doc = json.load(open('build/px4_sitl_default/px4_sitl_default.sbom.spdx.json'))
assert doc['spdxVersion'] == 'SPDX-2.3'
assert doc['dataLicense'] == 'CC0-1.0'
assert len(doc['packages']) > 0
print(f'Valid: {len(doc[\"packages\"])} packages')
"
```
For full schema validation, use the [SPDX online validator](https://tools.spdx.org/app/validate/) or the `spdx-tools` CLI.
## License Detection
Submodule licenses are identified through a combination of auto-detection and manual overrides.
### Auto-Detection
The generator reads the first 100 lines of each submodule's LICENSE or COPYING file
and matches keywords against known patterns.
Copyleft licenses (GPL, LGPL, AGPL) are checked before permissive ones
to prevent false positives.
Supported patterns include:
| SPDX Identifier | Matched Keywords |
| ----------------------------- | ------------------------------------------------------------------ |
| GPL-3.0-only | "GNU GENERAL PUBLIC LICENSE", "Version 3" |
| GPL-2.0-only | "GNU GENERAL PUBLIC LICENSE", "Version 2" |
| LGPL-3.0-only | "GNU LESSER GENERAL PUBLIC LICENSE", "Version 3" |
| LGPL-2.1-only | "GNU Lesser General Public License", "Version 2.1" |
| AGPL-3.0-only | "GNU AFFERO GENERAL PUBLIC LICENSE", "Version 3" |
| Apache-2.0 | "Apache License", "Version 2.0" |
| MIT | "Permission is hereby granted" |
| BSD-3-Clause | "Redistribution and use", "Neither the name" |
| BSD-2-Clause | "Redistribution and use", "THIS SOFTWARE IS PROVIDED" |
| ISC | "Permission to use, copy, modify, and/or distribute" |
| EPL-2.0 | "Eclipse Public License", "2.0" |
| Unlicense | "The Unlicense", "unlicense.org" |
If no pattern matches, the license is set to `NOASSERTION`.
### Override File
When auto-detection fails or returns the wrong result,
add an entry to `Tools/ci/license-overrides.yaml`:
```yaml
overrides:
src/lib/crypto/libtomcrypt:
license: "Unlicense"
comment: "Public domain dedication. Functionally equivalent to Unlicense."
```
Each entry maps a submodule path to its correct SPDX license identifier.
The optional `comment` field is emitted as `licenseComments` in the SBOM,
providing context for auditors reviewing complex licensing situations
(dual licenses, composite LICENSE files, public domain dedications).
### Copyleft Guardrail
The `--verify-licenses` command flags submodules with copyleft licenses
(GPL, LGPL, AGPL) in a dedicated warning section.
This is informational only and does not cause a failure.
It helps maintainers track copyleft obligations when adding new submodules.
### Platform Filtering
Submodules under `platforms/nuttx/` are excluded from POSIX and QURT SBOMs.
The `--platform` argument (set automatically by CMake via `${PX4_PLATFORM}`)
controls which platform-specific submodules are included.
This ensures SITL builds do not list NuttX RTOS packages.
### 验证
Run the verify command to check detection for all submodules:
```sh
python3 Tools/ci/generate_sbom.py --verify-licenses --source-dir .
```
This prints each submodule with its detected license, any override, and the final value.
It exits non-zero if any checked-out submodule resolves to `NOASSERTION` without an override.
Copyleft warnings are printed after the main table.
### Adding a New Submodule
1. Add the submodule normally.
2. Run `--verify-licenses` to confirm the license is detected.
3. If detection fails, add an override to `Tools/ci/license-overrides.yaml`.
4. If the license is not in the SPDX list, use `LicenseRef-<name>`.
### EU CRA Compliance
The EU Cyber Resilience Act requires SBOMs for products with digital elements.
The goal is zero `NOASSERTION` licenses in shipped firmware SBOMs.
Every submodule should have either a detected or overridden license.
The `--verify-licenses` check enforces this in CI.
## What's in an SBOM
This section is for integrators, compliance teams, and anyone reviewing SBOM artifacts.
### Where to Find SBOMs
| Location | Path |
| --------------- | ---------------------------------------- |
| Build directory | `build/<target>/<target>.sbom.spdx.json` |
| GitHub Releases | Alongside `.px4` firmware files |
| S3 | Same directory as firmware artifacts |
### Reading the JSON
Each SBOM is a single JSON document following SPDX 2.3.
Key fields:
- **`packages`**: Array of all components. Each has `name`, `versionInfo`, `licenseConcluded`, and `SPDXID`.
- **`relationships`**: How packages relate. `CONTAINS` means a submodule is compiled into firmware. `BUILD_DEPENDENCY_OF` means a tool used only during build.
- **`licenseConcluded`**: The SPDX license identifier determined for that package.
- **`licenseComments`**: Free-text explanation for complex cases (dual licenses, composite files, public domain).
- **`externalRefs`**: Package URLs (purls) linking to GitHub repos or PyPI.
### Understanding NOASSERTION
`NOASSERTION` means no license could be determined.
For submodules, this happens when:
- The submodule is not checked out (common in CI shallow clones).
- No LICENSE/COPYING file exists.
- The LICENSE file does not match any known pattern and no override is configured.
For shipped firmware, `NOASSERTION` should be resolved by adding an override.
For build-only dependencies (Python packages), `NOASSERTION` is acceptable
since these are not compiled into the firmware binary.

- **MAIN7:** motor 7 CCW, stern starboard vertical, propeller CW
- **MAIN8:** motor 8 CCW, stern port vertical, propeller CCW
## Basic Control Axes
For underwater vehicles, motion is defined in terms of body axes:
- **Surge:** forward/back motion - translation along the body X axis.
- **Sway:** left/right motion - translation along the body Y axis.
- **Heave:** up/down motion - translation along the body Z axis.
- **Yaw:** rotation about the (vertical) body Z axis.
### Stick Mapping (Mode 2)
The mapping below illustrates the default joystick behavior:
- **Pitch stick (forward/back):** surge
- **Roll stick (left/right):** sway
- **Throttle stick (up/down):** heave
- **Yaw stick (left/right):** yaw
![RC Basic Commands](../../assets/flying/rc_mode2_mc_position_mode.png)
## Manual Modes
| 模式 | 描述 |
| -------- | ---------------------------------------------------------------------------------------------------------------------------------------------------- |
| Manual | Direct manual control of yaw and thrust. |
| Acro | Manual control of yaw/thrust, but keeps roll/pitch zero |
| Altitude | Manual control of x/y thrust and yaw. Control of height with PID, manually controlled by user. Keeps roll/pitch zero |
| 安装位置 | Controls x/y/z and yaw. Manually controlled by user. Keeps roll/pitch zero |
The following manual and assisted modes are currently supported on BlueROV2 Heavy:
| 模式 | 描述 |
| ---------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Manual | Direct manual control of thrust and yaw. |
| Stabilized | Manual control of thurst and yaw with roll/pitch stabilization. |
| Acro | Manual control of yaw-rate and direct thrust commands with roll/pitch stabilization. |
| Altitude | Manual control of x/y thrust and yaw. Control of height with PID, manually controlled by user. Keeps roll/pitch stabilized. |
| 安装位置 | Controls x, y, z and yaw with position hold when sticks are released. Keeps roll/pitch stabilized. |
## Joystick Stick Mode
BlueROV2 supports two joystick mappings for manual control, selected using the
[UUV_STICK_MODE](../advanced_config/parameter_reference.md#UUV_STICK_MODE) parameter.
By default, `UUV_STICK_MODE` is set to `0`, which enables the UUV stick mapping intended for vectored underwater vehicles.
### UUV_STICK_MODE = 0 (default)
This mode is intended for normal BlueROV2 operation.
In `Manual`, `Stabilized`, and `Acro` modes, the sticks command:
- **Pitch stick:** surge - moving stick up -> moving forward, +X translation in body frame.
- **Roll stick:** sway - moving stick right -> moving sideways right, +Y translation in body frame.
- **Throttle stick:** heave - moving stick up -> moving upwards, -Z translation in body frame (note the Z axis points Down of the vehicle in PX4).
- **Yaw stick:** yaw - moving stick right -> yawing to the right, +Z rotation in body frame.
In this mode, roll and pitch are kept level rather than commanded directly.
### UUV_STICK_MODE = 1
This mode enables the legacy multicopter-style stick mapping for `Manual`, `Stabilized`, and `Acro` modes:
- **Throttle stick:** surge - moving stick up -> moving forward, +X translation in body frame.
- **Roll stick:** roll - moving stick right -> rolling to the right side, +X rotation in body frame.
- **Pitch stick:** pitch - moving stick up -> pitching down, -X translation in body frame (note signs are switched to follow PX4 standard).
- **Yaw stick:** yaw - moving stick right -> yawing to the right, +Z rotation in body frame.
This mode is mainly provided for compatibility with older setups and user preference.

At time of writing it has only been tested using ROS in offboard mode.
At time of writing manual and assisted manual modes are available for supported UUV frames, as well as ROS in offboard mode.
The following features have not been implemented:
- Modes like missions, depth hold, stabilised manual control, etc.
- Autonomous mission-style underwater workflows are still limited compared to aerial vehicles.

## Display-Only Mode
jMAVSim can run as a display-only renderer for other simulators (like [SIH](../sim_sih/index.md)), with its internal physics disabled.
In this mode, jMAVSim receives vehicle position via MAVLink and only renders the 3D view.
To use jMAVSim as a display for SIH running in SITL:
```sh
# Start SIH first
make px4_sitl_sih sihsim_quadx
# In another terminal, start jMAVSim in display-only mode
./Tools/simulation/jmavsim/jmavsim_run.sh -p 19410 -u -q -o # 19410 is the default SIH display port
```
For SIH running on flight controller hardware:
```sh
./Tools/simulation/jmavsim/jmavsim_run.sh -q -d /dev/ttyACM0 -b 2000000 -o
```
Use `-a` for airplane display or `-t` for tailsitter display.
## Command-Line Reference
The `jmavsim_run.sh` launch script accepts the following flags:
| Flag | 描述 |

| `-o` | Display-only mode (disable physics, render only) |
| `-a` | Use airplane model |
| `-t` | Use tailsitter model |
| `HEADLESS=1` | Environment variable: run without GUI window |
## How jMAVSim Works
jMAVSim is a Java-based lightweight simulator that communicates with PX4 via MAVLink HIL (Hardware-In-the-Loop) messages.
In normal mode:
1. PX4 sends actuator commands via [HIL_ACTUATOR_CONTROLS](https://mavlink.io/en/messages/common.html#HIL_ACTUATOR_CONTROLS).
2. jMAVSim runs its physics engine to compute the vehicle state.
3. jMAVSim sends sensor data back via [HIL_SENSOR](https://mavlink.io/en/messages/common.html#HIL_SENSOR) and [HIL_GPS](https://mavlink.io/en/messages/common.html#HIL_GPS).
In **display-only mode** (`-o` flag), jMAVSim disables its physics engine and only reads [HIL_STATE_QUATERNION](https://mavlink.io/en/messages/common.html#HIL_STATE_QUATERNION) messages to render the vehicle position.
This allows it to visualize vehicles from other simulators like SIH.
jMAVSim supports [lockstep synchronization](#lockstep) with PX4 (enabled with `-l` flag), ensuring deterministic simulation results.

# SIH on Flight Controller Hardware
SIH can run directly on flight controller hardware with `SYS_HITL=2`.
This replaces real sensors with simulated data while running on the actual autopilot, useful for testing without propellers.
For a comparison of SIH and HITL on hardware, see [Hardware Simulation](../simulation/hardware.md).
## Firmware Builds with SIH

:::info
Some boards (e.g., `px4_fmu-v6x_default`, `cubepilot_cubeorange_default`) do not include SIH in their default build due to flash memory constraints.
You can add SIH to any board -- see [Check if SIH is in Firmware](#check-if-sih-is-in-firmware).
:::
## Requirements
- A flight controller with SIH module included in firmware (see [Firmware Builds with SIH](#firmware-builds-with-sih)).
- USB connection for QGroundControl.
- Optional: jMAVSim for 3D visualization via serial link (see [Visualization](#hardware-visualization)).
## Check if SIH is in Firmware
SIH is included in most default firmware builds. To verify, search for `sih` in the parameter list in QGroundControl. If `SIH_*` parameters are available, the module is included.
To add SIH to a custom build, enable it in the board configuration:
```txt
CONFIG_MODULES_SIMULATION_SIMULATOR_SIH=y
```
## Starting SIH
1. Connect the flight controller to QGroundControl via USB.
2. Set `SYS_HITL` parameter to `2`.
3. Reboot the flight controller.
4. The SIH module starts automatically and provides simulated sensor data.
Once running, the vehicle can be controlled from QGroundControl or an RC controller.
:::warning
To save flash memory on boards with limited storage, SIH can be built with only quadrotor support.
Set `SIH_VEHICLE_TYPE` before building to limit included vehicle models.
:::
## Visualization (Optional) {#hardware-visualization}
If you need a visual aid to see what the simulated vehicle is doing on hardware:
### QGroundControl
Connect the flight controller via USB. QGC shows the vehicle on the map view with attitude, position, and telemetry, the same as a real flight.
### jMAVSim (3D Display-Only)
jMAVSim can render a 3D view of the vehicle over a serial connection. No physics are simulated in jMAVSim -- it is display-only.
```sh
./Tools/simulation/jmavsim/jmavsim_run.sh -q -d /dev/ttyACM0 -b 2000000 -o
```
Where `/dev/ttyACM0` is the serial device for the flight controller.
On macOS, this is typically `/dev/tty.usbmodem*`.
## Controlling Actuators
:::warning
If you want to control throttling actuators in SIH, make sure to remove propellers for safety.
:::
In some scenarios, it may be useful to control an actuator while running SIH on hardware. For example, you might want to verify that winches or grippers are functioning correctly by checking the servo responses.
**To enable actuator control in SIH:**
1. Configure PWM parameters in the airframe file:
Ensure your airframe file includes the necessary parameters to map PWM outputs to the correct channels.
For example, if a servo is connected to MAIN 3 and you want to map it to AUX1 on your RC, use the following command:
`param set-default PWM_MAIN_FUNC3 407`
You can find a full list of available values for `PWM_MAIN_FUNCn` [here](../advanced_config/parameter_reference.md#PWM_MAIN_FUNC1). In this case, `407` maps the MAIN 3 output to AUX1 on the RC.
Alternatively, you can use the [`PWM_AUX_FUNCn`](../advanced_config/parameter_reference.md#PWM_AUX_FUNC1) parameters.
You may also configure the output as desired:
- Disarmed PWM: ([`PWM_MAIN_DISn`](../advanced_config/parameter_reference.md#PWM_MAIN_DIS1) / [`PWM_AUX_DIS1`](../advanced_config/parameter_reference.md#PWM_AUX_DIS1))
- Minimum PWM ([`PWM_MAIN_MINn`](../advanced_config/parameter_reference.md#PWM_MAIN_MIN1) / [`PWM_AUX_MINn`](../advanced_config/parameter_reference.md#PWM_AUX_MIN1))
- Maximum PWM ([`PWM_MAIN_MAXn`](../advanced_config/parameter_reference.md#PWM_MAIN_MAX1) / [`PWM_AUX_MAXn`](../advanced_config/parameter_reference.md#PWM_AUX_MAX1))
2. Manually start the PWM output driver
For safety, the PWM driver is not started automatically in SIH. To enable it, run the following command in the MAVLink shell:
```sh
pwm_out start
```
**And to disable it again:**
```sh
pwm_out stop
```
## Adding New Airframes (FC)
Airframe configuration for SIH on a flight controller differs from SITL in a few ways:
- Airframe file goes in `ROMFS/px4fmu_common/init.d/airframes` and follows the naming template `${ID}_${model_name}.hil`, where `ID` is the `SYS_AUTOSTART_ID` used to select the airframe, and `model_name` is the airframe model name.
- Add the model name in `ROMFS/px4fmu_common/init.d/airframes/CMakeLists.txt` to generate a corresponding make target.
- Actuators are configured with `HIL_ACT_FUNC*` parameters (not the usual `PWM_MAIN_FUNC*` parameters).
This is to avoid using the real actuator outputs in SIH.
Similarly, the bitfield for inverting individual actuator output ranges is `HIL_ACT_REV`, rather than `PWM_MAIN_REV`.
For general airframe setup (SIH parameters, EKF2 tuning), see [Adding New Airframes](index.md#adding-new-airframes) on the main SIH page.
For examples, see the `.hil` airframes in [ROMFS/px4fmu_common/init.d/airframes](https://github.com/PX4/PX4-Autopilot/tree/main/ROMFS/px4fmu_common/init.d/airframes).

:::warning
This simulator is [community supported and maintained](../simulation/community_supported_simulators.md).
It may or may not work with current versions of PX4 (known to work in PX4 v1.14).
See [Toolchain Installation](../dev_setup/dev_env.md) for information about the environments and tools supported by the core development team.
:::
Simulation-In-Hardware (SIH) is an alternative to [Hardware In The Loop simulation (HITL)](../simulation/hitl.md) for quadrotors, fixed-wing vehicles (airplane), and VTOL tailsitters.
SIH can be used by new PX4 users to get familiar with PX4 and the different modes and features, and of course to learn to fly a vehicle using an RC controller in simulation, which is not possible using SITL.
SIH (Simulation-In-Hardware) is a lightweight, headless simulator with zero external dependencies that runs physics directly inside PX4 via uORB messages.
No GUI, no external processes, no rendering overhead — just PX4 running a C++ physics model.
This makes it the fastest way to iterate on flight code.
## 综述
With SIH the whole simulation is running on embedded hardware: the controller, the state estimator, and the simulator.
The Desktop computer is only used to display the virtual vehicle.
SIH runs as a PX4 module that replaces real sensor and actuator hardware with a simulated physics model.
It provides simulated IMU, GPS, barometer, magnetometer, and airspeed sensor data via uORB, and reads actuator outputs to update the vehicle state at each timestep.
![Simulator MAVLink API](../../assets/diagrams/SIH_diagram.png)
The simulation runs in lockstep with PX4, ensuring deterministic and reproducible results.
It also integrates seamlessly with ROS 2 via with no additional configuration (see [ROS 2 Integration](#ros-2-integration) below).
### Compatibility
Two modes are supported:
- SIH is compatible with all PX4 supported boards except those based on FMUv2.
- SIH for MC quadrotor is supported from PX4 v1.9.
- SIH for FW (airplane) and VTOL tailsitter are supported from PX4 v1.13.
- SIH as SITL (without hardware) from PX4 v1.14.
- SIH for Standard VTOL from PX4 v1.16.
- SIH for MC Hexacopter X from PX4 v1.17.
- SIH for Ackermann Rover from PX4 v1.17.
- **[SITL](#sih-as-sitl-no-fc):** Runs on your computer with no hardware needed, and headless (without a UI) by default.
_This is the fastest and easiest way to start a simulation on PX4._
### Benefits
- **[SIH on flight controller hardware](#sih-on-flight-controller-hardware):** Runs the entire simulation on the autopilot (`SYS_HITL=2`).
SIH provides several benefits over HITL:
### Supported Vehicle Types
- It ensures synchronous timing by avoiding the bidirectional connection to the computer.
As a result the user does not need such a powerful desktop computer.
- The whole simulation remains inside the PX4 environment.
Developers who are familiar with PX4 can more easily incorporate their own mathematical model into the simulator.
They can, for instance, modify the aerodynamic model, or noise level of the sensors, or even add a sensor to be simulated.
- The physical parameters representing the vehicle (such as mass, inertia, and maximum thrust force) can easily be modified from the [SIH parameters](../advanced_config/parameter_reference.md#simulation-in-hardware).
The following vehicle types are supported:
## Requirements
To run the SIH, you will need a:
- [Flight controller](../flight_controller/index.md), such as a Pixhawk-series board.
::: info
From PX4 v1.14 you can run [SIH "as SITL"](#sih-as-sitl-no-fc), in which case a flight controller is not required.
:::
- [Manual controller](../getting_started/px4_basic_concepts.md#manual-control): either a [radio control system](../getting_started/rc_transmitter_receiver.md) or a [joystick](../config/joystick.md).
- QGroundControl for flying the vehicle via GCS.
- Development computer for visualizing the virtual vehicle (optional).
## Check if SIH is in Firmware
The modules required for SIH are built into most PX4 firmware by default.
These include: [`pwm_out_sim`](../modules/modules_driver.md#pwm-out-sim), [`sensor_baro_sim`](../modules/modules_system.md#sensor-baro-sim), [`sensor_gps_sim`](../modules/modules_system.md#sensor-gps-sim) and [`sensor_mag_sim`](../modules/modules_system.md#sensor-mag-sim).
To check that these are present on your flight controller:
1. 启动QGroundControl。
2. Open **Analyze Tools > Mavlink Console**.
3. Enter the following commands in the console:
```sh
pwm_out_sim status
```
```sh
sensor_baro_sim status
```
```sh
sensor_gps_sim status
```
```sh
sensor_mag_sim status
```
::: tip
Note that when using SIH on real hardware you do not need to additionally enable the modules using their corresponding parameters ([SENS_EN_GPSSIM](../advanced_config/parameter_reference.md#SENS_EN_GPSSIM), [SENS_EN_BAROSIM](../advanced_config/parameter_reference.md#SENS_EN_BAROSIM), [SENS_EN_MAGSIM](../advanced_config/parameter_reference.md#SENS_EN_MAGSIM)).
:::
4. If a valid status is returned you can start using SIH.
If any of the returned values above are `nsh: MODULENAME: command not found`, then you don't have the module installed.
In this case you will have to add them to your board configuration and then rebuild and install the firmware.
### Adding SIH to the Firmware
Add the following key to the configuration file for your flight controller to include all the required modules (for an example see [boards/px4/fmu-v6x/default.px4board](https://github.com/PX4/PX4-Autopilot/blob/main/boards/px4/fmu-v6x/default.px4board)).
Then re-build the firmware and flash it to the board.
```text
CONFIG_MODULES_SIMULATION_SIMULATOR_SIH=y
```
:::details
What does this do?
This installs the dependencies in [simulator_sih/Kconfig](https://github.com/PX4/PX4-Autopilot/blob/main/src/modules/simulation/simulator_sih/Kconfig).
It is equivalent to:
```text
CONFIG_MODULES_SIMULATION_PWM_OUT_SIM=y
CONFIG_MODULES_SIMULATION_SENSOR_BARO_SIM=y
CONFIG_MODULES_SIMULATION_SENSOR_GPS_SIM=y
CONFIG_MODULES_SIMULATION_SENSOR_MAG_SIM=y
```
:::
As an alternative to updating configuration files manually, you can use the following command to launch a GUI configuration tool, and interactively enable the required modules at the path: **modules > Simulation > simulator_sih**.
For example, to update the fmu-v6x configuration you would use:
```sh
make px4_fmu-v6x boardconfig
```
After uploading, check that the required modules are present.
:::info
To use rover in SIH you must use the [rover build](../config_rover/index.md#flashing-the-rover-build) or add the rover modules to your board configuration.
:::
## Starting SIH
To set up/start SIH:
1. Connect the flight controller to the desktop computer with a USB cable.
2. Open QGroundControl and wait for the flight controller too boot and connect.
3. Open [Vehicle Setup > Airframe](../config/airframe.md) then select the desired frame:
- [SIH Quadcopter X](../airframes/airframe_reference.md#copter_simulation_sih_quadcopter_x)
- **SIH Hexacopter X** (currently only has an airframe for SITL to safe flash so on flight control hardware it has to be manually configured equivalently).
- [SIH plane AERT](../airframes/airframe_reference.md#plane_simulation_sih_plane_aert)
- [SIH Tailsitter Duo](../airframes/airframe_reference.md#vtol_simulation_sih_tailsitter_duo)
- [SIH Standard VTOL QuadPlane](../airframes/airframe_reference.md#vtol_simulation_sih_standard_vtol_quadplane)
- [SIH Ackermann Rover](../airframes/airframe_reference.md#rover_rover_sih_rover_ackermann)
The autopilot will then reboot.
The `sih` module is started on reboot, and the vehicle should be displayed on the ground control station map.

:::warning
The airplane needs to takeoff in manual mode at full throttle.
Also, if the airplane crashes the state estimator might lose its fix.
Only the quadrotor vehicle type is stable and recommended for development. All other vehicle types (hexarotor, fixed-wing, VTOL, rover) are experimental and may have aerodynamic model or controller interaction issues that produce unrealistic flight behavior.

## Simulation Configuration
### How SIH Works
### Wind
![SIH Overview](../../assets/simulation/sih_overview.svg)
SIH supports setting a wind velocity with the PX4 parameters [`SIH_WIND_N`](../advanced_config/parameter_reference.md#SIH_WIND_E) and [`SIH_WIND_E`](../advanced_config/parameter_reference.md#SIH_WIND_E) [m/s]. The parameters can also be changed during flight to simulate changing wind.
SIH differs from external simulators:
## Display/Visualisation (optional)
- **No MAVLink simulator API:** SIH communicates entirely via uORB (PX4's internal message bus).
- **No external process:** The physics model runs in the same PX4 process.
- **Lockstep by default:** Simulation time is synchronized with PX4 scheduling.
The SIH-simulated vehicle can be displayed using [jMAVSim](../sim_jmavsim/index.md) as a visualiser.
## SIH as SITL {#sih-as-sitl-no-fc}
:::tip
SIH does not _need_ a visualiser — you can connect with QGroundControl and fly the vehicle without one.
:::
SIH as SITL is the easiest and fastest way to set up a simulator with PX4.
It requires no hardware, and very few extra dependencies.
To display the simulated vehicle:
### Quick Start
1. Close _QGroundControl_ (if open).
2. Unplug and replug the flight controller (allow a few seconds for it to boot).
3. Start jMAVSim by calling the script **jmavsim_run.sh** from a terminal:
```sh
./Tools/simulation/jmavsim/jmavsim_run.sh -q -d /dev/ttyACM0 -b 2000000 -o
```
where the flags are:
- `-q` to allow the communication to _QGroundControl_ (optional).
- `-d` to start the serial device `/dev/ttyACM0` on Linux.
On macOS this would be `/dev/tty.usbmodem1`.
- `-b` to set the serial baud rate to `2000000`.
- `-o` to start jMAVSim in _display Only_ mode (i.e. the physical engine is turned off and jMAVSim only displays the trajectory given by the SIH in real-time).
- add a flag `-a` to display an aircraft or `-t` to display a tailsitter.
If this flag is not present a quadrotor will be displayed by default.
4. After few seconds, _QGroundControl_ can be opened again.
At this point, the system can be armed and flown.
The vehicle can be observed moving in jMAVSim, and on the QGC _Fly_ view.
## SIH as SITL (no FC)
SIH can be run as SITL (Software-In-The-Loop) from v1.14.
What this means is that the simulation code is executed on the laptop/computer instead of a flight controller, similar to Gazebo or jMAVSim.
In this case you don't need the flight controller hardware.
To run SIH as SITL:
1. Install the [PX4 Development toolchain](../dev_setup/dev_env.md).
2. Run the appropriate make command for each vehicle type (at the root of the PX4-Autopilot repository):
- Quadcopter
```sh
make px4_sitl sihsim_quadx
```
- Hexacopter
```sh
make px4_sitl sihsim_hex
```
- Fixed-wing (plane)
```sh
make px4_sitl sihsim_airplane
```
- XVert VTOL tailsitter
```sh
make px4_sitl sihsim_xvert
```
- 标准垂起固定翼
```sh
make px4_sitl sihsim_standard_vtol
```
- Ackermann Rover
```sh
make px4_sitl sihsim_rover_ackermann
```
### Change Simulation Speed
SITL allows the simulation to be run faster than real time.
To run the airplane simulation 10 times faster than real time, run the command:
To build PX4 and run SIH for a quadrotor:
```sh
PX4_SIM_SPEED_FACTOR=10 make px4_sitl sihsim_airplane
make px4_sitl_sih sihsim_quadx
```
To display the vehicle in jMAVSim during SITL mode, enter the following command in another terminal:
QGroundControl auto-connects on UDP port 14550 — just open it and you'll see the vehicle.
Note that the simulation is "headless" by default (has no GUI), but you can use an external viewer.
See [Supported vehicle types](#supported-vehicle-types) for other vehicles.
:::tip
Use the `px4_sitl_sih` build target!
The `px4_sitl` target will work, but will also build Gazebo libraries.
:::
### Visualization (Optional) {#sitl-visualization}
SIH is intentionally headless by default.
If you need a visual aid to see what the vehicle is doing you can use QGroundControl to track path over ground, and/or jMAVSim as a 3D viewer.
#### QGroundControl
QGC auto-connects on UDP port 14550. Open QGC while SIH is running and the vehicle appears on the map view with attitude, position, and telemetry.
#### jMAVSim (3D Display-Only)
jMAVSim can render a 3D view of the vehicle using MAVLink position data. No physics are simulated in jMAVSim — it is display-only.
```sh
./Tools/simulation/jmavsim/jmavsim_run.sh -p 19410 -u -q -o
```
- add a flag `-a` to display an aircraft or `-t` to display a tailsitter.
If this flag is not present a quadrotor will be displayed by default.
Flags:
### Set Custom Takeoff Location
- `-a` for airplane model
- `-t` for tailsitter model
- `-o` enable display-only mode.
The takeoff location in SIH on SITL can be set using environment variables.
This will override the default takeoff location.
See [jMAVSim Display-Only Mode](../sim_jmavsim/index.md#display-only-mode) for details.
The variables to set are: `PX4_HOME_LAT`, `PX4_HOME_LON`, and `PX4_HOME_ALT`.
### Environment Configuration
例如:
#### Change Simulation Speed
SIH supports faster-than-realtime simulation via the `PX4_SIM_SPEED_FACTOR` environment variable:
```sh
# Run at 10x speed
PX4_SIM_SPEED_FACTOR=10 make px4_sitl_sih sihsim_quadx
```
#### Wind Simulation
SIH supports setting a wind velocity with the PX4 parameters [`SIH_WIND_N`](../advanced_config/parameter_reference.md#SIH_WIND_E) and [`SIH_WIND_E`](../advanced_config/parameter_reference.md#SIH_WIND_E) [m/s]. The parameters can also be changed during flight to simulate changing wind.
#### Set Custom Takeoff Location
The default takeoff location can be set using environment variables:
```sh
export PX4_HOME_LAT=28.452386
export PX4_HOME_LON=-13.867138
export PX4_HOME_ALT=28.5
make px4_sitl sihsim_quadx
make px4_sitl_sih sihsim_quadx
```
### ROS 2 Integration
SIH works with ROS 2 via the [uXRCE-DDS](../middleware/uxrce_dds.md) client, which auto-starts in SITL mode.
This is the same mechanism used by Gazebo — both simulators expose the same set of uORB topics to ROS 2.
The DDS agent connects on UDP port **8888** by default (configurable via `UXRCE_DDS_PRT` parameter or `PX4_UXRCE_DDS_PORT` environment variable).
To use SIH with ROS 2:
1. Start SIH:
```sh
make px4_sitl_sih sihsim_quadx
```
2. In a separate terminal, start the Micro XRCE-DDS Agent:
```sh
MicroXRCEAgent udp4 -p 8888
```
See [uXRCE-DDS (PX4-ROS 2/DDS Bridge)](../middleware/uxrce_dds.md) for full setup instructions, including agent installation and ROS 2 workspace configuration.
### Port Reference
PX4 SITL opens the following UDP ports (all instance-aware, offset by instance number N).
| PX4 sends to (remote) | PX4 listens on (local) | Use for | Instance offset |
| ---------------------------------------- | ----------------------------------------- | -------------------------------------------------- | ------------------------------------------------------------ |
| **14550** | 18570 (+N) | QGroundControl, GCS tools | Yes |
| **14540** (+N) | 14580 (+N) | MAVSDK, MAVROS, offboard APIs | Yes (capped at 14549 for 10+ instances) |
| **14030** (+N) | 14280 (+N) | Onboard camera/payload | Yes |
| **13280** (+N) | 13030 (+N) | Gimbal control | Yes |
| **19410** (+N) | 19450 (+N) | jMAVSim display-only (SIH only) | Yes |
| **8888** | - | uXRCE-DDS / ROS 2 | No (use DDS namespace for multi-instance) |
QGC auto-connects on port **14550** by default. MAVSDK connects on **14540**. No manual port configuration needed for single-instance use.
### 基于gazebo的多飞行器仿真
SIH supports multi-vehicle simulation using PX4's instance system.
Each instance gets unique MAVLink ports, a unique system ID, and a separate DDS namespace.
To launch multiple SIH vehicles, first build:
```sh
make px4_sitl_sih sihsim_quadx
```
Then use the multi-instance launch script:
```sh
./Tools/simulation/sitl_multiple_run.sh 3 sihsim_quadx px4_sitl_sih
```
Or launch instances manually:
```sh
# Terminal 1 (instance 0)
make px4_sitl_sih sihsim_quadx
# Terminal 2 (instance 1)
./build/px4_sitl_sih/bin/px4 -i 1 -d ./build/px4_sitl_sih/etc
# Terminal 3 (instance 2)
./build/px4_sitl_sih/bin/px4 -i 2 -d ./build/px4_sitl_sih/etc
```
Each instance allocates ports automatically (all offset by instance number):
| Instance | MAVLink (18570+N) | MAVLink (14540+N) | DDS (8888) Namespace |
| -------- | ------------------------------------ | ------------------------------------ | --------------------------------------- |
| 0 | 18570 | 14540 | (default) |
| 1 | 18571 | 14541 | px4_1 |
| 2 | 18572 | 14542 | px4_2 |
See [Port Reference](#port-reference) for the complete list of ports.
## SIH on Flight Controller Hardware {#sih-on-flight-controller-hardware}
SIH can also run on flight controller hardware with `SYS_HITL=2`, replacing real sensors with simulated data while running on the actual autopilot.
See [SIH on Flight Controller Hardware](hardware.md) for setup instructions.
## Adding New Airframes
[Adding a new airframe](../dev_airframes/adding_a_new_frame.md) for use in SIH simulation is much the same as for other use cases.
You still need to configure your vehicle type and [geometry](../config/actuators.md) (`CA_` parameters) and start any other defaults for that specific vehicle.
:::warning
Not every vehicle can be simulated with SIH — there are currently [four supported vehicle types](../advanced_config/parameter_reference.md#SIH_VEHICLE_TYPE), each of which has a relatively rigid implementation in [`sih.cpp`](https://github.com/PX4/PX4-Autopilot/blob/main/src/modules/simulation/simulator_sih/sih.cpp).
Not every vehicle can be simulated with SIH — there are currently [six supported vehicle types](../advanced_config/parameter_reference.md#SIH_VEHICLE_TYPE) (quadcopter, fixed-wing, tailsitter, standard VTOL, hexacopter, rover), each of which has a relatively rigid implementation in [`sih.cpp`](https://github.com/PX4/PX4-Autopilot/blob/main/src/modules/simulation/simulator_sih/sih.cpp).

### SIH on Flight Controller
- Airframe file goes in `ROMFS/px4fmu_common/init.d/airframes` and follows the naming template `${ID}_${model_name}.hil`, where `ID` is the `SYS_AUTOSTART_ID` used to select the airframe, and `model_name` is the airframe model name.
- Add the model name in `ROMFS/px4fmu_common/init.d/airframes/CMakeLists.txt` to generate a corresponding make target.
- Actuators are configured with `HIL_ACT_FUNC*` parameters (not the usual `PWM_MAIN_FUNC*` parameters).
This is to avoid using the real actuator outputs in SIH.
Similarly, the bitfield for inverting individual actuator output ranges is `HIL_ACT_REV`, rather than `PWM_MAIN_REV`.

## Controlling Actuators in SIH
:::warning
If you want to control throttling actuators in SIH, make sure to remove propellers for safety.
:::
In some scenarios, it may be useful to control an actuator while running SIH. For example, you might want to verify that winches or grippers are functioning correctly by checking the servo responses.
To enable actuator control in SIH:
1. Configure PWM parameters in the airframe file:
Ensure your airframe file includes the necessary parameters to map PWM outputs to the correct channels.
For example, if a servo is connected to MAIN 3 and you want to map it to AUX1 on your RC, use the following command:
`param set-default PWM_MAIN_FUNC3 407`
You can find a full list of available values for `PWM_MAIN_FUNCn` [here](../advanced_config/parameter_reference.md#PWM_MAIN_FUNC1). In this case, `407` maps the MAIN 3 output to AUX1 on the RC.
Alternatively, you can use the [`PWM_AUX_FUNCn`](../advanced_config/parameter_reference.md#PWM_AUX_FUNC1) parameters.
You may also configure the output as desired:
- Disarmed PWM: ([`PWM_MAIN_DISn`](../advanced_config/parameter_reference.md#PWM_MAIN_DIS1) / [`PWM_AUX_DIS1`](../advanced_config/parameter_reference.md#PWM_AUX_DIS1))
- Minimum PWM ([`PWM_MAIN_MINn`](../advanced_config/parameter_reference.md#PWM_MAIN_MIN1) / [`PWM_AUX_MINn`](../advanced_config/parameter_reference.md#PWM_AUX_MIN1))
- Maximum PWM ([`PWM_MAIN_MAXn`](../advanced_config/parameter_reference.md#PWM_MAIN_MAX1) / [`PWM_AUX_MAXn`](../advanced_config/parameter_reference.md#PWM_AUX_MAX1))
2. Manually start the PWM output driver
For safety, the PWM driver is not started automatically in SIH. To enable it, run the following command in the MAVLink shell:
`pwm_out start`
And to disable it again:
`pwm_out stop`
## Dynamic Models
The dynamic models for the various vehicles are:
- Quadcopter: [pdf report](https://github.com/PX4/PX4-Autopilot/raw/main/docs/assets/simulation/SIH_dynamic_model.pdf).
- Hexacopter: Equivalent to the Quadcopter but with a symmetric hexacopter x actuation setup.
- Fixed-wing: Inspired by the PhD thesis: "Dynamics modeling of agile fixed-wing unmanned aerial vehicles." Khan, Waqas, supervised by Nahon, Meyer, McGill University, PhD thesis, 2016.
- Tailsitter: Inspired by the master's thesis: "Modeling and control of a flying wing tailsitter unmanned aerial vehicle." Chiappinelli, Romain, supervised by Nahon, Meyer, McGill University, Masters thesis, 2018.
- Ackermann Rover: Based on lateral vehicle dynamics of the bicycle model adapted from [Sri Anumakonda, Everything you need to know about Self-Driving Cars in <30 minutes](https://srianumakonda.medium.com/everything-you-need-to-know-about-self-driving-in-30-minutes-b38d68bd3427)
- Quadrotor: [pdf](https://github.com/PX4/PX4-Autopilot/raw/main/docs/assets/simulation/SIH_dynamic_model.pdf)
- Fixed-wing: based on Khan (2016), see references below
- Tailsitter: based on Chiappinelli (2018), see references below
- Rover: bicycle model with linear tire model
Since PX4 v1.17, the propeller model for fixed-wing, tailsitter, and VTOL pusher vehicles is based on [UIUC propeller data](https://m-selig.ae.illinois.edu/props/propDB.html).
The maximum thrust force is realistically reduced as aircraft speed increases.

# Hardware Simulation
PX4 can run simulation directly on a real flight controller, replacing real sensors with simulated data, while otherwise executing the full flight stack on actual autopilot hardware.
:::info
Simulating PX4 on flight controller hardware exercises more flight stack code than SITL, and tests more of your hardware integration.
It can surface issues with running PX4 that might hidden when running on a desktop OS and hardware, or even a different flight controller board.
:::
Two simulation approaches are available, controlled by the [SYS_HITL](../advanced_config/parameter_reference.md#SYS_HITL) parameter:
- **[HITL Simulation](../simulation/hitl.md) (`SYS_HITL=1`):** An external simulator (Gazebo Classic or jMAVSim) runs physics on a companion computer and sends sensor data to the flight controller via MAVLink HIL messages. Requires a USB/UART connection and simulator setup.
- **[SIH on Hardware](../sim_sih/hardware.md) (`SYS_HITL=2`):** A C++ physics model runs directly on the flight controller itself. No external simulator, no companion computer, no MAVLink sensor data. Just set the parameter and reboot.
## HITL vs SIH {#comparision}
| | HITL (`SYS_HITL=1`) | SIH (`SYS_HITL=2`) |
| ----------------- | ---------------------------------------------------------------------- | ---------------------------------------------------- |
| Physics model | External simulator (Gazebo Classic, jMAVSim) | Internal C++ module |
| Communication | MAVLink HIL messages | uORB (internal) |
| External process | Required | Not required |
| Setup complexity | Higher | Lower |
| Sensor simulation | Camera, lidar, etc. (via simulator) | IMU, GPS, baro, mag, airspeed only |
| Vehicle types | Quadcopter, Standard VTOL | Quad, Hex, FW, VTOL Tailsitter, Standard VTOL, Rover |
## When to Use Which
- Use **SIH** if you want the simplest possible setup. No external dependencies.
- Use **HITL** if you need an external physics engine, 3D visualization from Gazebo Classic, or camera/lidar sensor simulation that SIH does not provide.

For a detailed analysis of PX4 simulation user needs, priorities, and pain points, see the [PX4 Simulation Integration Survey Report](https://www.mcguirerobotics.com/px4_sim_research_report/) (K. McGuire, Dronecode Foundation, Dec 2025, 120 respondents).

### Which Simulator Should I Use?
- **Full-featured simulation with 3D rendering, custom worlds, camera/lidar sensors, or rich sensor ecosystems:** Use [Gazebo](../sim_gazebo_gz/index.md). Largest ecosystem, custom models and plugins, photorealistic rendering, extensive sensor library, large community.
- **Fast headless iteration, controls research, zero-dependency setup, or macOS:** Use [SIH](../sim_sih/index.md). Runs entirely inside PX4 with no external dependencies, headless by default for maximum speed, physics parameters directly tunable via `SIH_*` params. Supports ROS 2 via uXRCE-DDS.
- **Hardware integration testing without propellers:** Use [SIH on flight controller hardware](../sim_sih/index.md#sih-on-flight-controller-hardware) (`SYS_HITL=2`).
:::info
SIH is headless by default. For optional 3D visualization, you can use [jMAVSim in display-only mode](../sim_sih/index.md#visualization-optional) or monitor the vehicle in QGroundControl's map view.

## 仿真器 MAVLink API
All simulators except for Gazebo communicate with PX4 using the Simulator MAVLink API.
Most external simulators communicate with PX4 using the Simulator MAVLink API.
This API defines a set of MAVLink messages that supply sensor data from the simulated world to PX4 and return motor and actuator values from the flight code that will be applied to the simulated vehicle.
The image below shows the message flow.
:::info
SIH does not use the MAVLink simulator API. It runs physics internally via uORB messages. Gazebo communicates with PX4 via gz_bridge (Gazebo transport), not MAVLink.

Note, this is the successor of [Gazebo Classic](../sim_gazebo_classic/index.md) (below).
- [Gazebo Classic](../sim_gazebo_classic/index.md) is less accurate and less heavy-weight and supports many features and vehicles that aren't available for FlightGear.
It can simulate many more vehicles at a time than FlightGear and it allows for different types of vehicles to be simulated at the same time.
- JMAVSim is a very light-weight simulator that supports only quadcopters.
- [JMAVSim](../sim_jmavsim/index.md) is a very light-weight simulator that supports only quadcopters.
It is recommended if you need to support a lot of quadcopters, and the simulation only needs to be approximate.
- [SIH](../sim_sih/index.md) is the lightest-weight option with zero external dependencies.
Since SIH is headless and runs physics internally, it can launch many instances with minimal resource usage.
It supports all 6 vehicle types (quad, hex, plane, tailsitter, standard VTOL, rover).
