The Phantom 1, 2 & 3 use a barometer for altitude - not GPS (which is very inaccurate for altitude).I often wondered whether the P3 would recognize that you took off from say 800m that it would reflect though GPS etc.
The Phantom has no idea of height above sea level and only understands that home is zero and calculates everything relative to that.
