The GPS receiver uses a globe model? I am surprised by that as my N810 seems to get my attitude correct when I'm on an airplane when comparing to the inflight gps video.

Does GPS suffer from signal reflection? I notice that whenever I drive under a bridge my position is usually systematically offset.
