I am working with a drone that has flown many times, so it is a known good platform. I upgraded to PX4 v1.9.0. Now I cannot get this drone to go into auto mode (ie, green light). It keeps throwing error messages about preflight failures. In addition to “GPS speed accuracy too low”, sometimes I get “Horizontal speed position drift too high”. I’ve tried re-calibrating the sensors numerous times, but no help. I’m beginning to wonder if the Pixhawk controller is failing. Has there been any issues with v1.9.0?
Can anyone share any thoughts on this?
