Randy Mackay b4a8691a9e AP_NavEKF3: remove wheel encoder update limit 2019-10-22 07:15:48 +08:00
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.

Paul Riseborough 5b1d9ed868 AP_NavEKF3: Add missing vertical position derivative calculation 2019-10-18 11:15:25 +09:00
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

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

Michael du Breuil 9a7d64e8fc AP_NavEKF3: Allow the GPS to be responsible for logging 2019-09-10 09:09:17 +10:00
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

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

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

Andrew Tridgell a04aff7a7d AP_NavEKF3: added inter-EKF scheduling cooperation 
this changes the stragegy for load levelling between EKF cores so it
works between EK2 and EK3, and with future estimators as well.

It allows us to run EK3 and EK2 at the same time with good scheduling
performance

priseborough b862f0d7ad AP_NavEKF3: Enable use of GPS delay value from returned by the driver 
Use the time delay returned by the GPS driver.
Wait long enough for the GPS configuration to be determined, but time out after 30 seconds and warn the user that a default value for time delay will be used.

priseborough ed5039823f AP_NavEKF3: Adapt sensor buffer lengths 
Adapt the lengths of the IMU and observations buffers on startup to the specified time delays and update rates.
This does require the EKF to be re-started if time delays are changed.
