Paul Riseborough 842882355f AP_NavEKF3: increase innovation variance instead of clipping innovations 2023-08-16 17:56:43 +10:00
Paul Riseborough 573bd7c7f3 AP_NavEKF3: Provide option to clip velocity and position innovations 2023-08-16 17:56:43 +10:00
Andrew Tridgell d11d4fa0bf AP_NavEKF3: fixed velocity reset on AID_NONE
The ResetVelocity() function is only supposed to reset XY states, not
Z state. Resetting the Z state for velocity results in a large
velocity glitch if a vehicle is descending or ascending when aiding
switches to AID_NONE

this fixes #19386

Paul Riseborough c0d88e2673 AP_NavEKF3: Fix vertical velocity reset
Fixes bug that prevents the vertical velocity being reset to the GPS if the position aiding has already timed out and improves sensitivity of the bad IMU data check.

Andrew Tridgell fc2118f42b AP_NavEKF3: process GPS yaw independently of GPS fix
this processes GPS yaw with its own timestamp and as a separated step
from fusing position and velocity. This makes the yaw time handling
more accurate as yaw for moving baseline GPS comes in as a separate
piece of data from the position and velocity

Andrew Tridgell 6b73c2151a AP_NavEKF3: implement moving origin
this shifts EKF_origin to the current location at 1Hz, while leaving
public_origin alone. All output APIs and logging are relative to
public_origin.

The effect of this change is to remove the distortion caused by a
spherical earth, which allows the EKF to operate without errors at
very long distances from the public_origin.
