Hello everyone ı want to send velocity command on Alt_Hold mode. But send_velocity commmand only works when mode was GUIDED. How ı can change that ?
My main purpose is to keep the copter in the air without GPS. The copter I mentioned is connected to the ground controller by tether. I want to ensure that the copter always makes a 90 degree angle with the ground controller. And also I can always measure the angle made by the tether with the IMU on tether. So I want to control the copter with the angle of the tether without GPS.
Can anyone give me suggestions?
