## Встановлення
|
||||
|
||||
jMAVSim setup is included in our [standard build instructions](../dev_setup/dev_env.md) for Ubuntu Linux and Windows.
|
||||
Follow the instructions below to install jMAVSim on macOS.
|
||||
jMAVSim requires JDK 17 or later.
|
||||
On Ubuntu and Windows, the [standard development environment setup](../dev_setup/dev_env.md) scripts install all required dependencies including Java.
|
||||
On macOS, you need to install Java manually as shown below.
|
||||
|
||||
### macOS
|
||||
|
||||
To setup the environment for [jMAVSim](../sim_jmavsim/index.md) simulation:
|
||||
jMAVSim requires OpenJDK 17 or later.
|
||||
Install it via Homebrew:
|
||||
|
||||
1. Install a recent version of Java (e.g. Java 15).
|
||||
You can download [Java 15 (or later) from Oracle](https://www.oracle.com/java/technologies/downloads/?er=221886) or use [Eclipse Temurin](https://adoptium.net):
|
||||
```sh
|
||||
brew install openjdk@17
|
||||
```
|
||||
|
||||
```sh
|
||||
brew install --cask temurin
|
||||
```
|
||||
Homebrew installs OpenJDK but does not link it into your `PATH`, so you need to set `JAVA_HOME` for jMAVSim to find it.
|
||||
Add this to your shell profile (e.g. `~/.zshrc`):
|
||||
|
||||
2. Install jMAVSim:
|
||||
|
||||
```sh
|
||||
brew install px4-sim-jmavsim
|
||||
```
|
||||
|
||||
:::warning
|
||||
PX4 v1.11 and beyond require at least JDK 15 for jMAVSim simulation.
|
||||
|
||||
For earlier versions, macOS users might see the error `Exception in thread "main" java.lang.UnsupportedClassVersionError:`.
|
||||
You can find the fix in the [jMAVSim with SITL > Troubleshooting](../sim_jmavsim/index.md#troubleshooting)).

## 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

||||

||||

|
||||
| `-r <rate>` | Render rate in Hz |
|
||||
| `-l` | Enable lockstep |

||||

||||

|

## 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.
|
||||
|
||||

|
||||
| **S** | Stationary (fixed position) |

||||
| **G** | Gimbal (follows vehicle orientation) |
