Hi Back when the Z3801 was new, some GPS's would let you pick a specific geoid model to use for altitude. Apparently it's a receiver side choice of what model to use.

The 3801 seemed closer to right. If geoid error were the cause, it seems that both would indicate about the same. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
