Yes, nevertheless, the distinction between astronomical and geodetic
position could be relevant to some applications.  For that reason I'd
prefer to see something like
SITEGLON
SITEGLAT
SITEALON
SITEALAT
along with the relevant distinction between geoid height and elevation
vs. orthometric height that come along with curvature of the plumb line.

Do you have suggestions for spacecraft?
