latitude	Latitude in decimal degrees.
latitudeDirection	Latitude hemisphere indicator ('N' or 'S').
longitude	Longitude in decimal degrees.
longitudeDirection	Longitude hemisphere indicator ('E' or 'W').
timestamp	UTC time in hhmmss.ss format.
status	Data status indicator (typically 'A' or 'V').
modeIndicator	Mode indicator.
