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.
