F9 Alt Altitude above mean-sea-level (geoidal height) in meters
F10 M Units for altitude (M=meters)
F11 separation
Geoidal separation (difference between the WGS-84 earth ellipsoid
and mean-sea-level, where
“-” means mean-sea-level is below
ellipsoid) in meters.
Note: If no geoid is loaded, geoidal separation is reported as 0.
F12 M Units for geoidal separation (M=meters)
F13 age Time since last dGPS data was received in seconds
F14 Id
4-digit integer as denoted as XXYY, where XX is the StarFire satellite
beam in use (see Table 165), and YY is the GPS correction signal
type being used (see Table 166).
