Unfortunately I have a few problems with my Pixhawk. I use the Pixhawk with the 3DR uBlox GPS + Compass module. Sometimes I get the message, that a compass calibration is needed. But I did the calibration during the first setup. It seems that Pixhawk looses the compass values.... This is very strange... Another problem is the "Alt Disparity" error that shows up sometimes. Can somebody explain what this error causes? I have never got those errors on APM 2.6...
Many thanks in advance
