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.
