recently I wanted to fly with ArduCopter and Pixracer outdoors, controlled by MAVProxy without any internet connection. I could enter GUIDED-mode but when I tried to takeoff MAVProxy said “No map available” and refused the action. I do not exactly understand which map is meant. I started MAVProxy without the --map option. Where does this error come from? Does the GUIDED-mode require a internet connection at the ground station?
