This sounds like you have a barometer in your GPS, which I have not.
Nevertheless I get altitudes, and I would have thought they are not far
more off than the plane-coordinates, because GPS is "just"
triangulation. But from what you say I assume that the altitude
measurement provided by triangulation is even worse than the 40 metres
off. Is that true?

Harald.
