EKF errors

Hi folks!

I not very experienced with this but like to test out new stuff. I tested to load a flightplan and run it in SITL. Anyway i always get alarms from EKF like velocity variance and the it wont run. Quad was located outside and about 10 sat on gps.

Autodiag of logfile says VCC and GPS are good.
