#		GPS data header
# 	For GPS deployed on M3 mooring
# 	Deployment date 24 March 1998
#
# GPS  data records in this file contain 4 floating-point values and
# 2 integer values, as follows:
#
# time latitude longitude std_dev samples status
#
# time:  GMT time.  Format is ddd.fffff, for julian day and fraction of day.
# latitude:  Latitude in degrees north (floating point)
# longitude:  Longitude in degrees west (floating point)
# std_dev:  Standard deviation of position in meters (floating point)
# samples:  Number of samples taken to yield position and std_dev (integer)
# status:  Magellan receiver status word.  16 bit integer in hexadecimal,
#	   with following fields:
#	Bit 15: $PMGLH field 9, 0 = memory OK, 1 = lost memory
#	Bit 14: $PMGLH field 4, 0 = oscillator OK, 1 = out of tune
#	Bits 12-13: $PMGLH field 8, Almanac data, 00 = OK, 01 = no alm, 02 = old
#	Bit 11: $PMGLH field 3, 0 = backup battery OK, 1 = backup battery low,
#	Bits 8-10: $PMGLH field 10, status, as follows:
#			0 = Uninitialized
#			1 = Idle
#			2 = Search the Sky
#			3 = Collecting Almanac
#			4 = Collecting Ephemeris
#			5 = Acquiring satellite(s)
#			6 = Position
#			7 = Navigation mode (waypoint route)
#	Bits 4-7: $PMGLH field 5, signal quality (0 to 9)
#	Bits 0-3: $PMGLH field 6, geometric quality (0 to 9)
