Number of Satellites in Use
(Common satellites between ref and rover,
Values between 00 to 12, may be different
from the number in view)
GDOP
Ellipsoidal height
Antenna altitude above/below mean sea level.
Note, if no orthometric height is available the
local ell. height will be exported. If the local ell.
height is not available either, the WGS84 ell.
height will be exported.
