Paul Riseborough ebb8bb4f6f AP_NavEKF3: Enable use of yaw fusion before external yaw sensor starts 2020-04-11 21:14:31 +10:00
Andrew Tridgell 3ae0b0d446 AP_NavEKF3: added using_external_yaw() method 
needed by AHRS for attitudes_consistent() check
 2020-04-11 21:14:31 +10:00
Andrew Tridgell 6f04fae4a0 AP_NavEKF3: added fallback to mag option with external yaw 
this allows for a magnetometer to be used as a fallback yaw source in
flight when using an external yaw source such as a GPS. The
magnetometer bias is learned while the GPS yaw is available and
fallback is only done if the mag yaw and GPS yaw are consistent when
fallback is enabled

This also learns the Z gyro bias until first yaw alignment when
MAG_CAL is EXTERNAL_YAW_FALLBACK. This prevents large gyro bias
building while waiting for GPS lock
 2020-04-11 21:14:31 +10:00
Andrew Tridgell a3100251a8 AP_NavEKF3: use enum class for EK3_MAG_CAL values 
and use effective_magCal() everywhere for consistency

Andrew Tridgell be674fc36c AP_NavEKF3: make mag variance reporting consistent

Daniel Magree b3ff81648b Nav_EKF3: varInnovBodyVel assigned the innovation covariance, rather than inverse 2020-03-25 21:52:49 +11:00
Peter Barker 4c19eb4bab AP_NavEKF3: use compass reference rather than repeatedly asking AHRS for it 2020-03-13 08:26:18 +11:00
Andrew Tridgell 772438f3ed AP_NavEKF3: fixed use of antenna position when switching GPS primary 
when GPS primary switches we were using a position which had not been
corrected for antenna offset. This was used for calculating the reset
for sensor change.

This fixes that (trivial fix) and also fixes a similar issue on
position reset

Jaaaky 54f8e1137e AP_NavEKF3: added EK3_MAG_EF_LIM parameter 
Adapted from EKF2 implementation as of commits
3835d2613, e9ed3540f and df4fc0fff
this sets a limit on the difference between the earth field from the
WMM tables and the learned earth field inside the EKF. Setting it to
zero disables the feature. A positive value sets the limit in mGauss.

Randy Mackay 5baed38266 AP_NavEKF3: reduce EK3_HRT_FILT max to 30 2019-10-18 11:15:25 +09:00
Paul Riseborough 5b1d9ed868 AP_NavEKF3: Add missing vertical position derivative calculation 2019-10-18 11:15:25 +09:00
Andrew Tridgell c2067d5bc2 AP_NavEKF3: set a min yaw accuracy from GPS of 5 degrees 
GPS modules tend to be rather optimistic about their yaw accuracy. By
setting a min or 5 degrees we prevent the user constantly getting
warnings about yaw innovations
 2019-10-15 11:06:11 +11:00
Andrew Tridgell 3995db49a4 AP_NavEKF3: use parent class for intermediate static variables 
this makes the code faster as well as using less memory when both EK2
and EK3 are enabled
 2019-10-01 15:39:03 +10:00
Andrew Tridgell 0e3a27f74f AP_NavEKF3: change optimisation from -O3 to -O2 2019-09-28 08:57:26 +10:00
Andrew Tridgell 96c6544997 AP_NavEKF3: moved intermediate variables to common memory 
this moves intermediate variables from being per-core to being common
between cores. This saves memory on systems with more than one core by
avoiding allocating this memory on every core.

This is an alternative to #11717 which moves memory onto the stack. It
doesn't save as much memory as #11717, but avoids creating large stack
frames

Andrew Tridgell 05d62c62bb AP_NavEKF3: fixed use of uninitialised variable in EKF3 mag fusion 
not all elements of H_MAG are initialised, but they are used, as found
by valgrind

Andrew Tridgell fae2e44eac AP_NavEKF3: reset inhibitMagStates on in-flight yaw reset 
this is needed to prevent the next ConstrainVariances() from zeroing
the variances, which leads to very slow learning of mag states

Closes #11952
 2019-08-05 19:50:32 +10:00
Andrew Tridgell fc65e04ef2 AP_NavEKF3: fixed baro innovation gate when on ground with AIDING_NONE 
when on the ground without a position source we would disable the
innovation gate for the barometer. This meant that a single (or small
number of) really bad baro readings would be fused into the EKF,
causing it to destabilise

Fixes #11903

Andrew Tridgell 451fe840ee AP_NavEKF3: ensure that EKF origin stays in sync on all cores 
this prevents the EKF origin on different cores from being initialised
to different values. A common value is stored in the frontend and used
by a core if it doesn't have an origin
 2019-07-29 10:08:22 +10:00
Andrew Tridgell 0fcb2037e1 AP_NavEKF3: use origin lat for earth rates 
home may not yet be set when this code is run, so using home may be
invalid
 2019-07-29 10:08:22 +10:00
Andrew Tridgell a3411efdb5 AP_NavEKF3: set origin on all cores 
when EKF origin is set, make sure it is set on all cores
 2019-07-29 10:08:22 +10:00
Andrew Tridgell 3818d8ecda AP_NavEKF3: restrict setting of EKF origin 
only allow EKF origin to be set if EKx_GPS_TYPE is set to 3, which is
used for indoor operation

Andrew Tridgell b56914b879 AP_NavEKF3: use GPS yaw if available and enabled

Andrew Tridgell 3f9e48951b AP_NavEKF3: set terrainState to zero on height datum reset 2019-07-07 19:20:32 +10:00
Andrew Tridgell f3fc910abe AP_NavEKF3: continuously update gpsGoodToAlign 
use it to determine how to handle a height datum reset
 2019-07-07 19:20:32 +10:00
Andrew Tridgell b9a5794671 AP_NavEKF3: ensure that both AMSL and relative alt are correct after a reset 
this forces the EKF origin to the GPS alt on a height datum reset if
we have GPS lock. If we don't do this then the reported AMSL alt will
drift over time away from the GPS alt when we reset while on the
ground
 2019-07-07 19:20:32 +10:00
Andrew Tridgell 2208689893 AP_NavEKF3: don't use disabled gyros in opticalflow takeoff detection 2019-07-07 19:03:01 +10:00
Andrew Tridgell 209bca162c AP_NavEKF3: added inactive bias learning 
this allows for biases on inactive IMUs to be learned so that an IMU
switch within an EKF lane does not cause a jump in the IMU data
 2019-07-07 19:03:01 +10:00
Peter Barker ce45baa034 AP_NavEKF3: factor out and logging functions, reuse for 2nd core 2019-07-06 19:05:51 +10:00
Peter Barker f3f364de26 AP_NavEKF3: move logging in from AP_Logger 2019-07-06 19:05:51 +10:00
Andrew Tridgell 5151416080 AP_NavEKF3: force first EKF lane when disarmed 
this ensures we consistently fly with EKF lane1 if it is healthy at
the point we arm. Otherwise the choice of lane will be a lottery.

This is important as many systems have quite different filtering and
vibration characteristics on their different IMUs. We by default
enable fast sampling only on the first IMU for example, which means
the 2nd and 3rd IMUs are more vulnerable to high freq causing
aliasing.

Andrew Tridgell 60831c2878 AP_NavEKF3: added checkLaneSwitch() 
this allows the vehicle code to ask the EKF to change lanes if it is
about to do an EKF failsafe
 2019-06-12 09:52:20 +10:00
Peter Barker dce472745e AP_NavEKF3: take EAS2TAS from AHRS rather than airspeed 2019-06-06 12:44:36 +10:00

Randy Mackay 0a5d6a430a AP_NavEKF3: accept optical flow data at up to 50hz 2019-05-11 16:23:57 +09:00
Andrew Tridgell e4f6ffe719 AP_NavEKF3: fixed bug in EKF lane selection 
this fixes an issue in selecting the best lane to change to when we
have 3 or more EKF cores. The bug is that if the current lane is
unhealthy it would always choose the last healthy lane instead of
choosing the lane with the lowest score

Peter Barker 560f17a570 AP_NavEKF3: use union to alias array and struct access to states 
This avoids creating two pointers of different types to the same memory.

Having two pointers to the same memory can lead to the compiler
optimising code such that a write to one pointer is rearranged to be
either before or after a read from the other pointer depending on
which is deemed faster - not a good outcome.

Andrew Tridgell c13eaf0c7f AP_NavEKF3: removed create() method for objects 
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco
