I typed a long message but hit a key sequence that deleted it. ARRGH! Short form: Does the relative GPS position accuracy between position and height vary with latitude? If a receiver gives +-3 meter lat/lon and +- 10 meter height at the equator, as you move it toward the poles, seems the lat/lon accuracy will get worse. Does the height accuracy get worse at the same rate or some other? Just curious. Seems like the group that might have an answer. Related: For a typical position oriented GPS, how much worse is height accuracy than surface position at mid latitudes? Always ready to learn more. -Rex _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
