Hey guys I’m building a f450 with a pixhawk and I’m setting my board by qgroundcontrol, but when I try to test the motors, a message appears saying “no gps lock for vehicle” and it doesn’t let the motors starts. Another message is, “please check orientations and recalibrate”. Please help me, I don’t know more what to do.
Could you share with us the type of Pixhawk are you using and the FW version of PX4?
Are you trying to arm the vehicle with or without GPS? In which flight mode are you trying to arm?
Have you calibrated the sensors?
Here you have the preflight Sensors/Estimator Checks guide:
