MAVSDK's OffboardImpl::process_heartbeat() resets the setpoint state to
NotActive when a heartbeat without offboard mode arrives more than 3 s
after _last_started. _last_started is only ever written by start(), so
before the first start() it is epoch zero and the guard is always true:
any heartbeat that slips in between set_*() and start() makes start()
fail with NoSetpointSet.
At speed factor 30 PX4's 1 Hz (sim time) heartbeat arrives every ~33 ms
of wall time, which made 'Offboard attitude control' fail roughly one
run in three. Re-send the setpoint and retry start() in a small loop at
both offboard start sites. Failed 1/3 before, 16/16 after.
This is arguably a MAVSDK bug (_last_started should be initialized when
setpoint streaming begins); a retry keeps the tests robust either way.

* fix(navigator): remove generic reset of navigator triplets on mode change
- make each navigation mode decide if it needs the reset and what data it
wants to capture before the reset
- fix RTL climbing so that it remains on an established loiter when RTL
is being activated -> avoids weird trajectories and potential geofence breaches

* feat(mavsdk_tests): added various integration tests for loitering behavior:
- make sure RTL climb remains on established loiter
- make sure new loiter at current location is set when HOLD is engaged while
vehicle is transiting to another loiter
- make sure altitude is locked to current altitude when vehicle is currently
flying an established loiter but is transiting to a higher altitude
- make sure vehicle resets from figure of 8 to a loiter when HOLD is engaged
while vehicle is established on a figure of 8

* fix(navigator): harden geofence position checks and preserve loiter on breach
The GF_SOURCE_GPS path previously gated the breach check on the global
position timestamp even though it evaluated the fence against raw GPS
coordinates. Validate each source against the data it actually uses:
the fused global position on freshness (<1s), and raw GPS on freshness
(<2s) plus a valid fix.
For the LOITER breach action, only issue the reposition when the fused
global position is valid, since the setpoint is flown on that estimate,
and source all reposition coordinates from it. When the vehicle is
already established on a circular (orbit) loiter, keep that loiter's
center instead of re-centering on the current position to avoid a jump.

the previously used std::this_thread::sleep_for is with respect to host
system time which is different from autopilot time if:
- speed factor != 1
- something runs slower than realtime regardless of speed factor
- debugging or otherwise interrupting PX4 control code
tester.sleep_for (which already existed) correctly sleeps w.r.t.
px4/simulation time.
- add functionality to specify world name for simulation in case name
- add test for triggering an airspeed invalidation in case of pitot blockage

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
rename follow_me_status to follow_target_status
enable follow_target_estimator on skynode
implement the responsiveness parameter:
The responsiveness parameter should behave similarly to the previous
follow-me implementation in navigator. The difference here is that
there are now two separate gains for position and velocity fusion.
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
mantis: dont use flow for terrain estimation
follow-me: default responsiveness 0.5 -> 0.1
0.5 is way too jerky in real and simulated tests.

follow-me: minor comment improvement
follow-me: [debug] log emergency_ascent
follow-me: [debug] log gimbal pitch
follow-me: [debug] status values for follow-me estimator

It seems like we are often missing updates from topics like flight mode
or in air state, both topics that are sent out infrequenctly e.g. at 1
Hz. Therefore, instead of polling for that data we should probably
subscribe to the updates and that way get notified of each an every
update.
For instance this should prevent the case where we miss the mode change
from mission to descend and back to mission once landed and disarmed.
Depending on loop iterations for timeouts is not accurate, as usleep behavior depends on the system load and asking for a 0 ms sleep can potentially return immediately.
We had not actually properly adjusted the timeout to the lockstep speed
factor. Once we did that, we had to increase the timeouts quite a bit to
have the tests pass.
