GPS fix estimation allows to recover plane using magnetometer and baromener only.

Note, that GPS fix estimation is not a solution for navigation without GPS. Without GPS fix, position error accumulates quickly. But it is acceptable for RTH. This is not a solution for flying under spoofing also. GPS is the most trusted sensor in Inav. It's output is not validated.

GPS Fix is also estimated on GPS Sensor timeouts (hardware failures).

# How it works ?

In normal situation, plane is receiving it's position from GPS sensor. This way it is able to hold course, RTH or navigate by waypoints.
