How accurate is the GPS on the anafi Parrot?

Hi to all,

i have recently realized that the Anafi Parrot GPS module, isn’t quite accurate. After repeatedly executing the same mission by sending moveTo commands, the drone never follows the exact same waypoints (long - lat) defined in the mission script. The deviation error is in the range of +/- 2 meters.
This problem affects also the altitude, which is inaccurate too, and as a result half of the missions reproduces this +/- 2 meters deviation error.
Is this a hardware problem (of the GPS module), or is it something that has to do with the number of satelites and/or the movement of the satelites during the missions flights?
Any suggestion on how to overcome this problem, is more than welcome!
