To fly autonomous to a certain geo coordinate a GPS is needed. Although it is theoretically possible to use the original orange Parrot GPS dongle it is not advised, the performance is just not good enough for great autonomous flights. The solution that is advised is to use an uBlox GPS module.

  2. Cut a along the whole wire till the USB connector begin
  3. Peel ot the wires in the begin
  4. Grab all the wires of the cable end stringly in your hand
  5. With one continuous pull, pull the wires out of the black outer plastic. With a cut alone the line this shoud go, just apply force.
  6. You are done!
