Sounds like gps in not only inaccurate but inprecise as well. Throw out any value that does seem right? Voodoo. Full size planes travel at the same velosity for hundreds of miles and i find no problem with gps in that application. But an rc plane may travel at constant velosity for a few seconds, especially at 300+ mph.
Think of ot this way, the GPS units operate properly while under several Gs of acceleration. Obviously the velocity is changing while under this acceleration (DeltaV/DeltaT). THey still work fine. Check the specs.
GPS is used to guide precision munitions now. They accelerate at 1 G
