Mysterious GPS plot-patterns

Sorry for leaving you hanging on what we’ve been doing lately! In the mean time we’ve actually successfully tested the plane and watched it move about in the air (Insert wild cheers here). It was supposed to fly straight, but since the Trim did not reset during the manual flight up, we had it flying in tight circles. This problem has since been fixed, and we’re going to plan another test flight in the near future.

Here’s what we’ve been working on lately. The GPS is connected and transferring data, but there is a weird pattern showing up when the GPS is stationary. Perhaps this could provide a clue as to how to get even more accurate position data from the GPS alone.

Sorry about the audio quality by the way. It seems like the wifi was messing with the microphone–weird!
