Anna Dai 44200e9649 add GPS drop out case to GPS fusion logic ...

EKF waits 10s after GPS signal is lost before setting GPS control status flag to false. As the position information given by the alternative position sources drifts from the last GPS position, the controller over corrects.
With this update, the time horizon until GPS control flag set to false is reduced and only alternative position source is used for estimation.

tested with optical flow as position souce
