# 	For GPS deployed on M1 mooring
# 	Deployment date 4 Nov 1999
#
# GPS  data records in this file contain 4 floating-point values and
# 6 integer values, as follows:
#
# time latitude longitude std_dev samples time_on diffSamples hdop temp 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)
# time_on:  Number of seconds GPS receiver was powered on
# diffSamples:  Number of raw samples that were differential GPS
# hdop: Horizontal Dilution of Precision for last sample
# temp: Temperature of GPS receiver in degrees C
# status:  Garmin receiver status byte, in hex, with following fields:
#   (terminology is from Garmin manual.  I don't know what some of it means)
#	   Bit  0 = ROM checksum test, 1 = PASS, 0 = FAIL
#		1 = Receiver failure discrete, 1 = PASS, 0 = FAIL
#		2 = Stored data lost, 1 = Retained, 0 = Lost
#		3 = Real time clock lost, 1 = Retained, 0 = Lost
#		4 = Oscillator drift discrete, 1 = PASS, 0 = excessive drift
#		5 = Board configuration data, 1 = Retained, 0 = Lost
#		6,7 Unused
