That's strange, not for the position but for the altitude... unless
you happen to live in a very<br>
fortunate spot of earth surface, the reported altitude should change
depending on how many and<br>
which satellites are in view.... not only my Thunderbolt, but also
the GPS of my smartphone<br>
exhibits variations in function of the time of the day.<br>
