Disable GPS and compass

[Hunter Scott]

I tried unplugging the GPS module but got an error in qgroundcontrol that the compass is missing. Looks like there's one on the GPS board. What parameters do I need to change in qgc to disable GPS and the compass so I can arm and fly with the GPS module unplugged?

@Hunter-Scott , please try setting the following PX4 params to disable magnetometer :

• SYS_HAS_MAG to 0
• EKF2_MAG_TYPE to 5

Thanks, this worked!
