Hi there,

Now a test flight , my Pixhawk has entered into a Fail-safe EKF - 1 minute 2:12 appears for no reason .

After that time , the controller did not work properly until you have not regained control manually.

When connecting to the PC controller showed me these failures:

PREARM ACCELEROMETERS NOT HEALTHY
BAD GYRO HEALTH

I think it could be error SD card, but when I changed to another card, continued errors .

After recalibrate all sensors, now apparently works well , but I fear that the problem happens again .

Any help is very much appreciated. Regards . :frowning:

Hi there,

Today another attempt flight , and again , more errors EKF .

Error EKF_CHECK - 2 and another FAILSAVE_EKF -1.

After reconnecting whit telemetry, on the screen error:

BAD AHRS

Both days were quite windy , so the vibrations of the IMU .

I read thats errors can be related to the GPS … but can not find clear information.

I leave link to the new LOG
