Set this flag to true if local position is valid but accuracy low, such that
the operator can be warned before system switches to position-failure failsafe.
Additionally, switch to RTL if currently in Mission or Loiter to try to reach home
or fly out of GNSS-denied area.
Set low accuracy threshold to 50m by default for FW and VTOL.

Do the same as DO_REPOSITION wit only the altitude field populated
and MAV_DO_REPOSITION_FLAGS set, which means:
- switch to Loiter mode if not already in it
- set the current altitude to what is specified in the altitdue field,
keep current altitude setpoint otherwise
- keep current position setpoint
- fall back to current estimated position in case a position setpoint
is not finite

For the esc_calibration code, the actuator test is published for each motor
in a row. If the orb queue size is too small, messages are lost and not
received in mixer_module.
Set the default orb queue size of ActuatorTest high enough to keep the commands
for all motors in the queue.

- move EV yaw and EV position to new state machines
- EV yaw and EV pos now configured via EKF2_EV_CTRL (migrated from EKF2_AID_MASK)
- new EV position offset estimator to enable EV position while GPS position is active (no more EV pos delta fusion)
- yaw_align now strictly means north (no more rotate external vision aid mask)
- automatic switching between EV yaw, and yaw align north based on GPS quality
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].
Completely detach the steering wheel logic from the yaw controller (beside using the
same manual stick input in a manual flight mode).

- 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)
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.
It's enough that the setpoints and the unallocated values are logged, from these
the allocated values can be calculated if required.

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
delivery feature on PX4, however the future scope would extend this
feature out of Navigator, and rather move towards a federated PX4
(flight-mode flexibility) architecture. But until then, this will serve
the purpose.
Update Tools/sitl_gazebo submodule to remove sdf file overwrite error
- There was an error happening due to .sdf file being overwritten, it
was caused by a wrongfully added. sdf file.
- This update pulls in the PR commit: https://github.com/Auterion/sitl_gazebo/pull/147
Initial cut on supporing PAYLOAD_PLACE mission item
Tidy and comment on navigation.h to clarify mission item definition
- Convert vehicle command ack subscription data type to
SubscriptionData, to not care about having a dedicated struct for
copying the latest data
- Tidy and comment on navigation.h to clarify the definition of
mission_item_s, which is confusing as it is an intergration of MAVLink
Standard into PX4's internal Mission Item structure
Rename mission_block's mission item reached function & cleanup navigator
- Isolated Handle Vehicle Commands function inside the Navigator
- Rename mission_block's mission item reached function to 'reached or
completed', as the navigation command can also be an action (e.g.
DO_SET_SERVO, which doesn't make sense to refer to as 'reached' when we
have successfully done executed the command)
Include MAVLink PR commit to include payload_drop message
More changes to add payload_drop MAVLink message support
- Comitting for testing purposes
Add mission item payload_drop to vehicle command payload drop link
- Now with a mission item with the nav_cmd set to 'payload drop', the
appropriate 'payload drop' vehicle command will be issued
Make Payload drop executable via Mission Plan
Implement payload_drop module to simulate payload delivery
- Simple module that acknowledges the payload drop vehicle command after
certain time, to simulate a successful delivery
Additional changes - payload drop module not working yet
- Need to do more thread stuff to make it work :(
Fix Payload Drop enum mismatch in vehicle_command enums
- First functional Payload Drop Implementation MVP
- Simple Ack & resuming mission from Navigator tested successfully
Hold the position while executing payload drop mission item
- Still the position hold is not solid, maybe I am missing something in
the position setpoint part and all the internal implications of
Navigator :(
Add DO_WINCH command support
Some fixes after rebase on develop branch
- 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
- Initialization of the Gripper position to CLOSED on Constructor of the
payload_drop module
- Setting the OPEN and CLOSED value to the appropriate actuator controls
input
Set vehicle_command_ack message's timestamp correctly
- By not setting the timestamp, the ack commands were not correctly
graphed in PlotJuggler!
Rename payload drop module to payload deliverer
- I think it's a more complex name (harder to type), but more generic
Add Gripper class (WIP)
Add Gripper class functionalities
- Add gripper uORB message
- Add gripper state machine
Use Gripper class as main interface in payload_deliverer
- Utilizes Gripper class functions for doing Gripper functionality
Remove mixer based package delivery trigger logic
- Remove custom mixer files that mapped actuator controls to outputs
statically
Additional improvements of the payload_deliverer
Fix payload_deliverer module not starting
- _task_id wasn't geting set appropriately in task_spawn function, which
led to runtime failure
Add Gripper Function to mixer_module
- Still not showing up as function mapping in QGC, needs fix
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 double call for ` ${R}etc/init.d/rc.vehicle_setup`
- Was introduced during the rebase
- Was causing module already running & uORB topic can't be advertised
errors
Fix format via `make format` command
Modify S500 airframe file to use for control allocation usage
- Added Control allocation related parameters as default to not have it
reset every time the airframe is selected
Implement mission specific payload deploy timeout and more changes
Switch payload_deliverer to run on work queue
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
-always reset roll/pitch/yaw integrators at the same time

- ekf2: add new helper to get roll/pitch/yaw covariances
- mavlink: receiver ODOMETRY handle more frame types for both pose (MAV_FRAME_LOCAL_NED, MAV_FRAME_LOCAL_ENU, MAV_FRAME_LOCAL_FRD, MAV_FRAME_LOCAL_FLU) and velocity (MAV_FRAME_LOCAL_NED, MAV_FRAME_LOCAL_ENU, MAV_FRAME_LOCAL_FRD, MAV_FRAME_LOCAL_FLU, MAV_FRAME_BODY_FRD)

- landing slope/curve library removed
- flare curve removed (the position setpoints will not be tracked during a flare, and were being ignored by open-loop maneuvers anyway)
- flare curve replaced by simply commanding a constant glide slope to the ground from the approach entrance, and commanding a sink rate once below flaring alt
- flare is now time-to-touchdown -based to account for differing descent rates (e.g. due to wind)
- flare pitch limits and height rate commands are ramped in from the previous iteration's values at flare onset to avoid jumpy commands
- TECS controls all aspects of the auto landing airspeed and altitude/height rate, and is only constrained by pitch and throttle limits (lessening unintuitive open loop manuever overrides)
- throttle is killed on flare
- flare is the singular point of no return during landing
- lateral manual nudging of the touchdown point is configurable via parameter, allowing the operator to nudge (via remote) either the touchdown point itself (adjusting approach vector) or shifting the entire approach path to the left or right. this helps when GCS map or GNSS uncertainties set the aircraft on a slightly offset approach"

the variable holding the length

- As it is always only used for the vehicle command ack message
- It was a duplicate, hence making it error prone for maintainment
- The uORB message comments were updated to make the relationship with
the MAVLink message / enum definitions clear
split the fusion process into:
1. updateAirspeed: computes innov, innov_var, obs_var, ...
2. fuseAirspeed: uses data computed in 1. to generate K, H and fuse the
observation
If the PPS GPIO is exposed to a signal with high frequency changes, a lot of
interrupts are scheduled and the handling of these calls can worst-case
starve flight critical processes leading to a loss of
control. Since PPS is not flight critical, we now give up the PPS
functionality and stop the interrupts to prevent the starvation of other processes.
- all sources of optical flow publish sensor_optical_flow
- sensor_optical_flow is aggregated by the sensors module, aligned with integrated gyro, and published as vehicle_optical_flow

The responsiveness parameter should behave similarly to the previous

The previous implemenation in navigator had no velocity fusion.
Allow follow-me to be flown without RC
SITL tests for follow-me flight task
This includes:
- Testing the setting for the follow-me angle
- Testing that streaming position only or position
and velocity measurements both work
- Testing that RC override works
Most of these tests are done with a simulated model
of a point object that moves on a straight line. So
nothing too spectacular. But it makes the test checks
much easier.
Since the estimator for the target actually checks new
measurements and compares them to old ones, I also added
random gausian noise to the measurements with a fixed seed
for deterministic randomness. So repeated runs produce
exactly the same results over and over.
Half of the angles are still missing in MAVSDK. Need to create
an upstream PR to add center left/right and rear left/right options.
These and the corresponding SITL tests need to be implemented
later.
sitl: Increase position tolerance during follow-me
Astro seems to barely exceed the current tolerance (4.3 !< 4.0)
causing CI to fail. The point of the CI test is not to check
the accuracy of the flight behaviour, but only the fact that the
drone is doing the expected thing. So the exact value of this
tolerance is not really important.
follow-me: gimbal control in follow-me
follow-me: create sub-routines in flight task class
follow-me: use ground-dist for emergency ascent
dist_bottom is only defined when a ground facing distance sensor exist.
It's therefore better to use dist_ground instead, which has the distance
to the home altitude if no distance sensor is available.
As a consequence it will only be possible to use follow-me in a valley
when the drone has a distance sensor.
follow-me: point gimbal to the ground in 2D mode
follow-me: another fuzzy msg handling for the estimator
follow-me: bugfix in acceleration saturation limit
follow-me: parameter for filter delay compensation
