Andrew Tridgell 1d46e77942 AP_Common: make longitude_scale() a static 
this changes the use of longitude_scale() to use the average latitude
instead of the lattitude at one end of the line when calculating
positions and distances. It means we obey the basic geometry rule
that:

 pos1 + offs = pos2
 pos2 - offs == pos1

Andrew Tridgell f0bc4bca84 HAL_ChibiOS: run storage writes at 1kHz not 100Hz 
The 100Hz update rate means there is a significant chance of an arming
failure after mission upload if you try to arm shortly after the
update.

Each mission item is 15 bytes, so with a 1200 item mission we need to
write 18000 bytes to storage. At 100Hz, with 8 bytes per storage line,
that takes over 22 seconds.

Peter Barker 156a220d5b AP_NavEKF3: pass NavEKF failures back up to callers 2021-07-22 16:01:00 +10:00
Andrew Tridgell 9f03f5a9a9 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 cc03255245 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.
