EKF: Scale position observation noise with GPS quality
...
This allows the filter to adapt to variations in GPs quality.
The range of adjustment in observation noise is limited to the range between a lower limit set by the GPS observation noise parameter and an upper limit set by the no-aiding observation noise.

EKF: Improve use of position and velocity observation noise parameters
...
Fix bug where noise parameters were not being squared when calculating the observation variance.
Use GPS reported speed accuracy to set velocity observation noise and use the parameter to set the minimum.

fix delta angle bias usage:
...
the delta angle bias was applied to imu data which was not coming in the same
time intervall as the filter was operating. Therefore, the delta angle bias
applied to new imu data had to be scaled correctly in order to match
the imu time interval.
