Remember that GPS normally displays altitude with respect to the WGS84 datum
geoid, not with respect to MSL. There can easily be a hundred feet or so of
difference.

Hello fellow time nuts,
after the thunderbolt roll over problem I run the survey control in Lady
Heather (48h).
Since then I am getting always a wrong elevation number for my qth.
Does anybody know the reason for that behavior?
Is there a solution to get again the correct value?
Kind regards
