For the Phantom Vision you do not need anything but the Vision App on an Android or an iPhone/iPad. You have to enable waypoints in the Vision App and then you will have access to the screen used to set and execute waypoint missons. You cannot use a PC to fly waypoints on any of the Phantom models. Does the Ground Station software you are referring to run on a PC? If so that is actually for flying DJI controlled multi-rotors using the A2 or Naza flight controllers.
