Daniel Agar cea185268e msg ROS2 compatibility, microdds_client improvements (timesync, reduced code size, added topics, etc), fastrtps purge
- update all msgs to be directly compatible with ROS2
 - microdds_client improvements
   - timesync
   - reduced code size
   - add to most default builds if we can afford it
   - lots of other little changes
 - purge fastrtps (I tried to save this multiple times, but kept hitting roadblocks)

Daniel Agar f9509b442c ekf2: height aid source consistency (#20405)
- working towards keeping all height source (baro/ev/gnss/rng) handling as consistent as possible, possibly refactoring these out into separate classes later

ekf2: merge mag 3d innov var, Hx and Kx computation to reduce flash

Slightly less code produced, almost no performance change

ekf2_mag3D: do not pre-compute Kalman gains

The vector of Kalaman gains is not too expensive to compute using
matrix-vector multiplication. Pre-generating it using CSE takes a lot of
flash space for little benefit.

Daniel Agar 116bb6049f ekf2: fusion helper consistency
- yaw fusion use measurementUpdate()
 - fuseVelPosHeight() respect _accel_bias_inhibit (like measurementUpdate())

Daniel Agar 2de990fd4b estimator_aid_source split GNSS pos (3d) -> pos (2d) + hgt
- per estimator air source status only keep a single set of flags and
timestamp that applies to the entire source

bresch 5f54f6fcda ekf2: migrate sideslip fusion to SymForce
- split fusion into update (compute innov and innov_var) and actual fusion to the state vector
- use estimator_aid_source_1d struct to group the data

bresch f753b92cff ekf2: start fake pos fusion after dead-reckoning timeout
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

bresch bb790c9bec ekf2: add vertical dead-reckoning timeout check for height validity 2022-09-29 14:16:36 -04:00
Ville Juven 59e86c490d Remove include <log.h> from defines.h
The reason for this is that log.h includes drv_hrt.h which sucks in
half the project's include files with it, which causes strange build
issues

Daniel Agar 1f7080a710 ekf2: extend sensor bias stability requirement
- for accel/gyro/mag estimated bias only consider them stable (valid
for calibration updates) if the value isn't changing (10% of limit) over
the validity period

Daniel Agar 38d332a553 ekf2: inhibit accel bias dynamically when fake position/height fusion active
- inhibit accel bias learning dynamically depending on the angle between an accelerometer and the vertical axis when fake position fusion is active

bresch 6bd81c0eb7 ekf2: do not store delayed baro sample in class
the sample is popped from the buffer and directly used; there is no
need to keep a local copy of it

bresch ae1e12a6b5 ekf2: remove baro accumulation from initializeFilter 2022-09-10 12:29:29 -04:00
bresch fe4a6ce8de ekf2: allow initialization without baro data when fusion is disabled 2022-09-10 12:29:29 -04:00
bresch a54fa7b9b1 ekf2: add fake height fusion logic
When there is no vertical aiding, fake height is started to constrain
the vertical channel of the EKF

bresch aa716936bf ekf2: move synthetic_position flag to control_status.flags.fake_pos 2022-09-10 12:29:29 -04:00
bresch a2a5093881 ekf2: relax zero velocity update
The ZVU is too strong and prevents the EKF from following variations in
the height aiding sources, creating large innovations.

Daniel Agar d996af4647 ekf2: pass gpsSample around where required
- this minimizes potential misuse accessing _gps_sample_delayed and
makes the dependency clear
2022-09-05 10:27:19 -04:00
Daniel Agar 7bbdc220f5 ekf2: initialiseFilter() simplify mag heading init and resetQuatStateYaw
- most of resetQuatStateYaw doesn't apply to initial heading init, so
removing the special case keeps it simple

Daniel Agar 5cb44a521c ekf2: estimator interface handle sample time with signed integers
- this prevents unsigned integer overflow if the timestamp is smaller
than the configured delay (mostly a simulation edge case)
2022-09-01 09:47:29 -04:00
Daniel Agar 1948c5057a ekf2: handle all time on delayed horizon (except for newest sample checks)
- a growing number of samples come into the backend with the time
already delayed (sensor's interrupt setting timestamp sample)
 - if the incoming timestamp is already delayed then the new data checks
(relative to latest IMU) can be slightly wrong
 - handle almost all timestamps and checks on delayed time horizon,
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
