This checks was introduced to catch the (unlikely) case of the driver publishing
a stale value that is not actually from a current measurement right after boot.
This was done by declaring it invalid if there is no update of the measurement
within the first 10s after boot.
Practice though has shown that around 0, many airspeed sensors have such a low
resolution that the reported airspeed value is often at the exact same value
for longer periods of time on totally healthy sensors, and thus we trigger
some false positive failure detections.
Given that this failure mode (driver publishing stale data) is quite rare (if
it doesn't receive new data it should stop publishing), I remove this check
here again.
When in aerodynamic flight mode and armed, there is still the data stuck
check that can trigger if there is no update for 2s.

Instead of always starting with instance 0 (potentially an internal
mag), first take the current sensor as reference to compare the other
ones against it.
The issue is that otherwise we can end up in a
situation where a switch occurs because the currently used sensor isn't
much better than a sensor with a lower index: because the selected one
isn't much better, we cannot "fail-over" to it and get stuck on another
sensor, triggering a fail-over.
- WelfordMeanVector now computes covariance
- use Kahan summation for Welford mean (but continue using float32 for actual mean, etc)
- WelfordMean and WelfordMeanVector handle initial value and count roll over
- Welford mean count rollover at 16 bit max to prevent numerical issues and shift weight to newer samples
- sensors/vehicle_imu: update Welford mean usage (now simplified with resets removed)
- fix vehicle_imu_status accel var, now properly rotated with full covariance matrix
- gyro_calibration: update Welford mean usage
This is fully backwards compatible: If the throttle trim is set to
the minimum then it's the legacy calibration and gets
interpreted such that there is no trim and behavior remains as before.
If the trim is set to a different value than the minimum then it gets
used like with all other channels which was unsupported before.
In review it was requested to have a different name for
manual_control_setpoint.z because of the adjusted range.
I started to investigate what naming is most intuitive and found
that most people recognize the stick axes as roll, pitch, yaw, throttle.
It comes at no surprise because other autopilots
and APIs seem to share this convention.
While changing the code I realized that even within the code base
the axes are usually assigned to a variable with that name or
have comments next to the assignment clarifying the axes
using these names.
To be consistent with all other axes of stick input and avoid future
rescaling confusion.
Note: for the MAVLink message 69 MANUAL_CONTROL it's using the full range
according to the message specs now [-1000,1000].

- also put flaring internal states into a struct to organize a bit
- one concern with blending the throttle setpoint like this with the flare time param is that folding prop belly landing airframes may want to have a separate param for shorter throttle kill and still use the flare time ramps for everything else
abruptly changing to a heading setpoint on flare can cause the aircraft to roll and deviate from the runway, this commit

1. the wind would need to be considered, and an appropriate diagonal approach (obstructions allowing) defined to the runway

- start runway ops from idle throttle
TECS climbout mode was used for takeoff climbout, which puts throttle to full and does not regulate a specific airspeed.
This commit sets the desired takeoff airspeed explicitly and allows max climb rate to track the ascent.
previously a scale factor param on min airspeed was used to define the climbout airspeed for runway takeoff
additionally, the rotation speed was defined by another hardcoded scale on top of the previously scaled min airspeed
this commit explicitly defines a takeoff speed and rotation speed for runway takeoff in params, with option to disable
Before, the logic to update disarm and rate values also triggered during
bootup on the px4io, because the output functions are only set in
updateSubscriptions().
Therefore change the check to prevent updating during the first cycle.
When using ignition SITL simulation with NO_LOCKSTEP, the SITL PX4 fails to update the IMU data from Ignition Gazebo.
The timestamp for the IMU data is taken from the ignition message:
- In LOCKSTEP mode the clock from the ignition simulation and the one from PX4 SITL are synchronized, hence everything works fine
- In NO_LOCKSTEP mode, those clocks are not synchronized anymore, so the timestamp for the IMU data should not be the one from Ignition but the current time in PX4 SITL when receiving the message.
The update function of InputMavlinkGimbalV2 returns UpdatedNotActive when receiving control commands from a system or component that doesn't match the primary control. This can happen if a component just sends commands without being in control or when transitioning to a different primary control.
If the input is marked as already_active, it will reset last_input_active which in turn resets the primary control in the next iteration. According to the MAVLink gimbal protocol v2, a component needs to send MAV_CMD_DO_GIMBAL_MANAGER_CONFIGURE to start controlling the gimbal and to remove control. However, with the current implementation there are several other commands that would reset the primary control.
With this PR, the primary control remains with the component that requested it last if updates from a not active component are received.

Fixes a regression from 8bae4e5c0e, where
the orbit flight task wasn't an extra task (flight_tasks_to_add) anymore
and therefore the command handling wasn't generated.
There was a race condition that could cause several outcomes. The most severe
was that flight_mode_manager gets the command, switches to orbit and then
in the next iteration switches back because commander did not change
nav_state yet. When commander then switches, flight_mode_manager would still
be in the old mode.
This is prevented by storing the command (allowing it to arrive before or
after mode switch), and then apply it after the switch happens.
- vehicle_angular_velocity and vehicle_angular_acceleration are produced together from the same input data, consumed together, and share the the same metadata (timestamps)
- individually these topics each have 16 bytes of metadata (2 timestamps) for 12 bytes of data (x,y,z float32)
During the whole flight, if the difference between the yaw estimate from
EKF2 and the emergency estimator is large and that the GNSS velocity
fusion is failing continuously, immediately reset to the emergency yaw
estimate.
- with Ekf::initialiseFilter() resetting _time_last_hagl_fuse the terrain estimate was technically valid regardless of any range or flow data availability and as a result optical flow fusion is able to start and stay active
- only consider terrain estimate valid based on control status flags and recent fusion
The CameraFeedback module used only the vehicle attitude for the camera orientation so far. With this change, the gimbal_device_attitude_status is used to compute the global camera orientation when a gimbal is used.
In this case it did not cause any problems.

previous change in logic to hold after mission clear also broke rtl, as non-mission takeoff still published a mission result which allowed entering the mission finished condition and always changing state to loiter (ignoring rtl). new logic only switches navigation states if mission is finish and the nav state is explicitly in takeoff state, or in mission state
The srcparser.py is specific to each use case (e.g. Airframes, Parameters, px4events, etc as in Tool/* folders).
Therefore it is confusing to have the px_process_airframes.py script handle concept of airframes under the generic name 'params'.
This improves readability and sets the baseground for implementing more specific vehicle type supports, as mentioned in https://github.com/PX4/PX4-user_guide/pull/1858#discussion_r876554728
once the rampup starts. The rampup requires a valid vertical velocity setpoint.
The corner case is:
- We are before takeoff and amending the setpoint to be 0,0,100 acceleration
in order to idle
- The rampup starts BUT the setpoint is not yet overwritten by the trajectory
setpoint topic
- The idle setpoint gets amended to not contain a feed-forward vertical
acceleration because the rampup is velocity based
- The result is a brief invalid 0,0,NAN acceleration setpoint
- That invalid setpoint gets overridden by a failsafe that holds zero velocity
- Zero velocity leads to applying ~hover thrust briefly
- buffer at least 2 samples for the IMU output predictor buffers
- dropping below 2 becomes problematic for the minimum observation
interval calculation and the vertical output buffer trapezoidal
integration
arm
- Previously, due to the way MAVSDK's `health_all_ok` was implemented,
vehicle often didn't have a valid global position estimate (although
function returned true), and it wouldn't arm, and the SITL would fail
- Also sometimes as vehicle didn't have manual control, it entered weird
states where it wasn't able to arm as well
- This adds a check to make sure vehicle is able to arm, directly from
the Health struct
- preflight mag bias estimate is in the vehicle body frame and removed from the raw mag data after it's rotated, calibrated, etc
- in flight mag bias (from ekf2) is in the vehicle body frame, but stored as a sensor frame offset immediately

It's very important that the in descend detection is always
at a strictly higher velocity than the vertical movement check.
This combination is basically used to check for vertical downwards
velocity tracking. Desired descend, no movement -> ground
If in descend threshold is lower than vertical movement it is
by definition even with perfect tracking the case that with
any velocity between the two thresholds there is no movement
even though a descend is commanded.
See first fix of this problem #7831e39b38ba96
I don't see where this is necessary. During takeoff, the maybe landed flag should
only get cleared once system is about to takeoff, and thus well after the spool up

* Added the px4_platform_common/defines.h include to the matrix library math.hpp header to pull
in some non-standard M_PI constants and updated the test files to use those constants.
* Fixed PI constants in matrix helper test to prevent test failure
before there was a corner case where if in an auto mode that sets a reset command on the attitude setpoint message (e.g. auto takeoff), if the mode was then switched stabilized, this reset bool would never be changed back to false and the integrators would reset every cycle
* Removed dprintf from perf library since it is only ever used with fd=1 (STDOUT) so moved to PX4_INFO_RAW instead. This helps with some platforms (e.g. Qurt) which have some Posix support but not full Posix support.
This was previously required to reset the flight speed after a VTOL transition,
but is now no longer required as the DO_CHANGE_SPEED commands are handles directly
in the controllers.

Refactor
- Require reboot for PD_GRIPPER_EN parameter change
- Define gripper ACTION_NONE for readability. This makes implicit assumption that -1 equals no-action commanded more explicit
- Tidy the scattered vcmd_ack struct handling cases into a single function
- Refactor to remove return in the middle of function: avoids future complications where a programmer may expect the logic at the end of the function to be executed, but isn't
Vehicle Command Handling
- Cancel the previous running vehicle command if we receive a different vehicle command
- Reject vehicle command if we get a same one that is getting executed
- Save the source system & component of currently running vehicle command
- Added note about new discovered edge case of having same entity sending different gripper commands consequently, where an unexpected ack result may be received
Gripper:
- Don't command gripper (via uORB `gripper` topic, which maps into an
actuator via Control Allocation) if we are already at the state we want
(e.g. Grabbed / Released) or in the intermediate state to the state we
want -> This prevents spamming on `gripper` topic
Payload Deliverer:
- Add read-once function for Gripper's released / grabbed state
- Send vehicle_command_ack for both release/grab actions.
TODO: target_system & target_component for the released/grabbed vcmd_ack
is incomplete, since we are not keeping track of the vehicle_command
that corresponds to this. This needs to be dealt with in the future, not
sure what the best solution it is for now.
Possible solutions:
- Queue-ing the vehicle command?
- Tying the gripper's action to specific vehicle command one-on-one, to make sure if we send multiple vehicle commands, we know
which command resulted in the action exactly?)
Only command Gripper grab when we are actually initializing gripper
- Previously, on every parameter update, gripper grab was being
commanded
- This commit narrows that scope to only when we are actually
initializing the gripper
Handle gripper de-initialization upon parameter change
- Also added some local state initialization code to init() function of
Gripper
- This will now make init / de-init more graceful & controlled compared
to before
- This hopefully then alerts the GCS that the command is getting
processed
- Referenced commander's `handle_command` function to implement this. As
it seems like GCS needs the acknowledgement of the command being
processed to execute such commands properly
- Also send FAILED command ack if we can't actuate the gripper
Fix wrong GRIPPER_ACTION conversion from floating point to int32_t
- Due to the MAVLink spec, we actually just convert enums into floating
point, so in PX4 we need to convert the float directly into integer as
well (although there can be precision issues on large numbers)
- This is a limitation in MAVLink spec, and should hopefully be
changed in MAVLink v2

- relax timeout before a notch filter is disabled
- add new parameter IMU_GYRO_DNF_MIN for configuring the minimum notch filter frequency
- avoid the possibility of unsigned underflow from subtracting two HRT timestamps (uint64_t)
- most of these aren't problematic, but people tend to replicate the pattern, so it's better to be safe

Moves the arming checks before the command handling.
This reduces the chance of race conditions. However it does not prevent
them! The SDK will need to check when offboard is ready to run/arm to fix
this.
Specifically this is for sitl offboard tests, where offboard_control_mode
is updated and immediately after a mode switch into offboard is commanded.
- trajectory_setpoint and vehicle_local_position_setpoint used to be
the same data type
- we got extremely lucky here that this didn't cause any issues due to
all the fields still aligning
Starting the fake position as soon as all the aiding sources stop makes
the local position immediately invalid while we could continue to navigate
for a couple of second with inertial dead-reckoning
- vehicle_imu_status can publish immediately on any measured sample
rate change or sensor error increment, but the windowed mean/variance
shouldn't necessarily reset that often
This is to prevent that that data from non-recent publications of the virtual
attitude setpoints are used in the transition code.
It removes the previous implementation where the update_transition_state()
method was only run when both mc and fw virtual att sp where recent, independetly
of whether both are used or not.

- Previously it was hard to check which state the gripper was in
(GRAB/GRABBED/ etc), not even whether it was correctly initialized, this
commit adds that functionality
- When the gripper was uninitialized, the error message popped up
everytime the module had 'any' vehicle command received. But we should
be spamming only when we do actually get 'DO_GRIPPER' command received,
this commit adds that feature
- Also converted error messages for CLI when gripper test functinality
fails, so that user would get a feedback (originally, the PX4_DEBUG was
of course not outputting everything)

This new check is inteded to trigger if there is no data variation published by
the airspeed driver for the first 10s after the first data is published.
This is to capture malfunctioning sensors/drivers that do publish a value, this
value though does not come from real sensor measurements.
Previously this was captured by the data stuck check, but it has shown that
some drivers can publish a stuck value without being actually malfunctioning
(e.g. when the airspeed is outside of their measurement range). Checking for
any data variation is the more conservative check that still catches the above
described failure case.

If the current yaw setpoint is valid we should use it to make the transition in this direction.
For a VTOL_TAKEOFF the yaw_setpoint is used to specify the transition direction (the
vehicle is aligned towards it and then transition is started). The current yaw can be
a bit off (e.g. because MIS_YAW_ERR is large), and it is better to track the actual setpoint.

This feature allows user to use a Gripper type pacakge delivery
mechanism on a drone to trigger the delivery during a mission via the
mission item `DO_GRIPPER`.
This is a minimal change that is intended to have simplest pacakge

feature out of Navigator, and rather move towards a federated PX4
(flight-mode flexibility) architecture. But until then, this will serve
the purpose.

- Some missed brackets
- Some comment edits, etc
Add DO_WINCH command support
- Still has a problem of flying away from the waypoint while the
DO_WINCH is being executed, probably position setpoint related stuff :(
Apply braking of the vehicle for DO_WINCH command
- Copies the behavior of NAV_CMD_DELAY, which executes a smooth, braking
behavior when executing the delay because of the braking condition in
`set_mission_items` function
- This will not apply to Fixed wings
- The payload deploy getting triggered may be too early, as right now as
soon as the vehicle approaches the waypoint within the acceptance
threshold, the payload gets deployed
Add DO_GRIPPER support
Implement Gripper actual Hardware triggering support
- Currently not working, possibly in the mixer there's a bug
- Implemented the publishing of actuator_controls_1 uORB topic
- Implemented the test command for the payload_drop module, to test the
grpiper functionality
- Edited px4board file to include the payload_drop module
- Added Holybro X500 V2 airframe file, to enable testing on X500 V2
- Created new Quad X Payload Delivery mixer, which maps the actuator
controls 1 topic's data into the MAIN pin 5 output
Make Payload Drop Gripper Work

Add parameters to control gripper behavior
- Now user can enable / disable gripper
- Also select which type of gripper to use
Applying review from nuno
Remove timeout fetching from mission item and use gripper's timeout
- Previously, it was planned to use a custom DO_GRIPPER and DO_WINCH
MAVLink message definitions with information on timeout, but since now
we are using original message definition, only relevant timeout
information is defined in the payload_deliverer class
- This change brings in the timeout parameter to the Navigator, which
then sets the timeout in the mission_block class level, which then
processes the timeout logic
Make payload deployment work for Allmend test :P
Support gripper open/close test commands in payload_deliverer
Move enum definition for GRIPPER_ACTION to vehicle_command.msg

Remove unnecessary files
- Airframe changes from enabling control allocation are removed
Address review comments
- Remove debug messages
- Remove unnecessary or verbose comments & code
- Properly call parameter_update() function
Switch payload_deliverer to scheduled interval work item & refactor
- Switch to Schedeuled on Interval Work Item, as previous vehicle
command subscription callback based behavior led to vehicle comamnd ack
not being sent accordingly (since the Run() wouldn't be called unless
there's a new vehicle command), leading to ack command not being sent
out
- Also, old vehicle commands were getting fetched due to the
subscription callback as well, which was removed with this patch
- Fix the wrong population of floating point param2 field of vehicle
command by int8_t type gripper action by creating dedicated function
- Refactor and add comments to increase readability
Add gripper::grabbing() method and handle this in parameter update
- Previously, the intermediate state 'grabbing' was not considered, and
when the parameter update was called after the first initialization of
the gripper, the grab() function was being called again, which would
produce unnecessary duplicate vehicle command.
- Also replaced direct .grab() access to sending vehicle comamnd, which
unifies the gripper actuation mechanism through vehicle commands.
Navigator: Change SubscriptionData to Subscription to reduce memory usage
- Also removed unused vehicle command ack sub
PayloadDeliverer: Remove unnecessary changes & Bring back vehicle_command sub cb
When hitting zero thrust by stick there is 0 torque authority
without airmode. So 0% minimum manual thrust should never be the default
without airmode.
Uses COM_SPOOLUP_TIME to slowly ramp the throttle and allow the
tailrotor to compensate in a coordinated way based on the yaw
compesation from throttle, see CA_HELI_YAW_TH_S.
This coordinated spoolup is necessary to avoid unsafe yaw twitches
because of the heli rotating until the correct compensation kicks in
through the feedback controller.
Move logic implemented in the header files to source files, this way
it will be simpler to define which is compiled to kernel space and
which to user space
Also allows to remove some headers that pull in half the universe
from the board definitions (which should just be pin definitions and
no functionality)

except for explicit checks of new samples
- isRecent() and isTimedOut() helpers use delayed time
- add new isNewestSampleRecent() used for checking the incoming
timestamp of the incoming (adjusted) data
- print list of events whenever they change if
CONSOLE_PRINT_ARMING_CHECK_EVENT is set, instead of on each update call
- reduce flash usage by moving out templated code into non-template method

- ignition_simulator renamed to simulator_ignition_bridge
- large sitl_target.cmake split by simulation option and in some cases pushed to appropriate modules
- sitl targets broken down to what's actually available (eg jmavsim only has 1 model and 1 world)
- new Gazebo consistently referred to as Ignition for now (probably the least confusing thing until we fully drop Gazebo classic support someday)
Also remove the legacy "range aid" than can be achieved by setting the
height reference to range finder and the range finder control parameter
to "conditional".
Conditional range aiding cal also be set when the height reference isn't
the range finder. This prevents the ratchetting effect due to switching
between references.
Instead of having a single height source fused into the EKF and the
other ones "waiting" for a failure or the primary sensor, fuse all
sources in EKF2 at the same time. To prevent the sources from fighting against each
other, the "primary" source is set as reference and the other ones are
running a bias estimator in order to make all the secondary height
sources converge to the primary one.
If the reference isn't available, another one is automatically selected
from a priority list. This secondary reference keeps its current bias
estimate but stops updating it in order to be the new reference as close
as possible to the primary one.
- much simpler direct interface using Ignition Transport
- in tree models and worlds
- control allocation output configuration, no more magic actuator mapping to mavlink and back
- currently requires no custom Gazebo plugins (keeping things as lightweight and simple as possible)

Since the horizontal and vertical velocity controllers are now
decoupled, it can be that the horizontal acceleration produced by the
controller is actually greater than the desired one (by design). This
condition would actually make the ARW run "backwards", degrading the
controller performance.
Directly use yaw controls for it, and don't add it to the allocation matrix,
as that would have an effect on rudder scaling if the wheel also would have
a yaw effectiveness.

2fbb70d9ca made the lowest possible
throttle value commanded by stick in Stabilized mode before taking off 0.
The real world problem with this is that when takeoff is detected then
the entire throttle scaling range jumps from
[0, MPC_MANTHR_MIN]
to [MPC_MANTHR_MIN, MPC_MANTHR_MIN].
As a result whenever MPC_MANTHR_MIN is not zero there is a thrust jump
on every takeoff just at the moment takeoff is detected even when the
stick is moved continuously.
Because of this I suggest to revert to having a higher throttle value
from the beginning on because it's less complicated and there's
no obvious value in starting out with zero thrust if anyways not
possible to go back to zero for safety once takeoff is detected.
