The command is sent by a dedicated mavlink command and forwarded to the fixed wing position controller.
The pattern is defined by the radius of the major axis, the radius of the minor axis and the orientation. The pattern is then defined by:
The upper part of the pattern consist of a clockwise circle with radius defined by the minor axis. The center of the circle is defined by the major axis minus the minor axis away from the pattern center.
The lower part of the pattern consist of a counter-clockwise circle with the same definitions as above.
In between, the circles are connected with straight lines in a cross configuration. The lines are always tangetial to the circles.
The orientation rotates the major axis around the NED down axis.
The loitering logic is defined inside its own class used by the fixed wing position control module. It defines which segment (one of the circles or lines) is active and uses the path controller (npfg or l1-control) to determine the desired roll angle.
A feedback mavlink message is send with the executed pattern parameters.
Dataman: Add write function to dataman cache.
RTL and mission have a new common base class mission_base. Both inherit from them and mission, RTL mission, and rtl reverse mission inherit from them and implement their desired functionalities. This simplifies the logic in mission as well as make the logic in rtl mission reverse and mission more readable.
Rtl mission reverse now functional again for VTOL flying back the mission and transitioning to MC at the home position.
Dataman cache has new write functionality to write to dataman while updating write item in its cache if necessary.
Dataman cache is now only updated when the respective module is active. Leads to a higher computation time once on activation, but decreases unnecessary cache updates when inactive.
This estimate doesn't converge to the true yaw but can be used as a
more consistent but drifting heading source.
It can be used by a setpoint generator to adjust its heading setpoint
while the true yaw estimate is converging in order to keep a constant
course over ground.
- when GNSS is used require low mag heading innovations during
horizontal acceleration (yaw observable) to validate the mag
- only fuse mag heading just enough to constrain the yaw estimate
variance to a sane value. Leave enough uncertainty to allow for a
correction when the yaw is observable through GNSS fusion
- split mag_3d into new standalone mag fusion and mag fusion allowed to update all states (full mag_3d)
- new dedicated control logic for mag/mag_3d fusion and standalone mag heading fusion
- if WMM available use for mag_I and mag_B init
- mag states reset if external yaw reset (yaw estimator, GPS yaw, etc)
- mag reset if declination changed (eliminate _mag_yaw_reset_req)
- mag fusion (but not mag_hdg or mag_3d) can be active during gps_yaw or ev_yaw (if yaw aligned north)

- simplify vehicle_status.arming_state down to just armed and disarmed
- ARMING_STATE_INIT doesn't matter
- ARMING_STATE_STANDBY is effectively pre_flight_checks_pass
- ARMING_STATE_STANDBY_ERROR not needed
- ARMING_STATE_SHUTDOWN effectively not used (all the poweroff/shutdown calls loop forever in place)
- ARMING_STATE_IN_AIR_RESTORE doesn't exist anymore
- collapse ArmStateMachine into commander
- all requests already go through Commander::arm() and Commander::dismarm()
- other minor changes
- VEHICLE_CMD_DO_FLIGHTTERMINATION undocumented (unused?) test command (param1 > 1.5f) removed
- switching to NAVIGATION_STATE_TERMINATION triggers parachute command centrally (only if armed)

Case: A vehicle is already operating but has no stick input or another
source than RC. When RC stick input is switched to either because it gets
first time available or as a fallback to joystick then the mode was
immediately changed to the switch position. This can lead to loss of
control e.g. when the vehicle is flying far away and the
mode switch of the RC is in some fully manual piloted mode.
I added tests to cover the cases where RC mode initialization is expected
and also unexpceted because the vehicle is already armed.
- if the height rate input into TECS is finite, use that one to
update a velocity reference generator
- if the velocity reference generator reports position locked or
height rate input is not finite, then run altidue reference generator
- run altitude controller only if altitue is controlled
if height_rate_setpoint is set, only use that one to update altitdue trajectory

Camera controls should not happen through the flight controller, and
the control allocation has no means of controlling the camera zoom.

- remove deprecated actuator_controls[INDEX_FLAPS/SPOILERS/AIRBRAKES]
- use new topic normalized_unsigned_setpoint.msg (with instances flaps_setpoint
and spoilers_setpoint) to pass into control allocation
- remove flaps/spoiler related fields from attitude_setpoint topic
- CA: add possibility to map flaps/spoilers to any control surface
- move flaps/spoiler pitch trimming to CA (previously called DTRIM_FLAPS/SPOILER)
- move manual flaps/spoiler handling from rate to attitude controller
FW Position controller: change how negative switch readings are intepreted
for flaps/spoilers (considered negative as 0).
VTOL: Rework spoiler publishing in hover
- pushlish spoiler_setpoint.msg in the VTOL module if in hover
- also set spoilers to land configuration if in Descend mode
Allocation: add slew rate limit of 0.5 to flaps/spoilers configuration change
Instead of doing the flaps/spoilers slew rate limiting in the FW Position Controller
(which then only is applied in Auto flight), do it consistently over all flight
modes, so also for manual modes.

- remove deprecated actuator_controls[INDEX_LANDING_GEAR]
- remove dead code in mc rate controller that used to prevent it from being retracted
on the ground (anyway had no effect as it only affected the actuator_control[LANDING_GEAR]
which wasn't sent to the control allocation)
- for VTOLs handle deployment/retraction of landing gear in AUTO as a MC (retract if
more than 2m above ground, deploy if WP is a landing WP), plus additionally when transition
flight task is called (ALTITUDE mode and higher)
- for FW in AUTO: add logic in FW Position Controller, depending on waypoint type mainly
- manual landing gear settings always come through (a manual command overrides a previous
auto command, and vice-versa)

Tiltrotor_extra_controls also contains collective thrust beside collective tilt, as passing a 3D
thrust setpoint vector beside the tilt is not feasible.

- always publish esc_status
- when enabled via MODAL_IO_VLOG param, enable actuator debug output
- for modal_io commands, use ESC HW ID values instead of motor number for easier use
- publish esc_status message for command line commands
- Uncommented the code that fills in the cmdcount and power fields in the esc_status topic

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.
