Follow used guided but references the maximum velocity settings. As Guided does not set maximum velocities these values come back as zero. So we need to reference WP_Nav to get safe maximums.

Andrew Tridgell
4b2c766857 AP_GPS: change handling of moving baseline yaw
this changes yaw handling in a few ways:

 - GPS yaw now has a timestamp associated with the yaw separate from
   the timestamp associated with the GPS fix

 - we no longer force the primary to change to the UBLOX MB rover when
   it has a GPS yaw. This means we don't change GPS primary due to GPS
   loss, which keeps the GPS more stable. It also increases accuracy
   as the rover is always less accurate in position and velocity than
   the base

 - now we force the primary to be the MB base if the other GPS is a
   rover and the base has GPS lock

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.

9f03f5a9a9 AP_NavEKF3: process GPS yaw independently of GPS fix
this processes GPS yaw with its own timestamp and as a separated step

this shifts EKF_origin to the current location at 1Hz, while leaving

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.
