I read “SET_ATTITUDE_TARGET - this is the only message accepted by Guided_NoGPS” and the body pitch, roll and yaw rate inputs are disabled. which mean I cannot control that from Guided_NoGPS mode. The only way is to give it X, Y,Z position target and it will move to that position. Is this correct?
If it is correct it means I need an initial position lock and then a gps denied position estimation device like Optical flow(which I have). So does it mean I need a GPS to get initial position lock?
Thanks in advance!
