The antenna altitude is either ellipsoidal (default) or geoidal (mean-sea-level) depending on the
selection made with $PASHS,HGT (see UCT section). The geoidal altitude can be also derived by
subtracting the geoidal separation from the ellipsoidal altitude.
Typical UTM message:
$PASHR,UTM,015454.00,10S,588757.623,4136720.056,1,04,03.8,
