As we mentioned in the previous sections,
MGL-30
can be used as an ordinary
real-time GPS locator (to output general NMEA messages), and
in the mean time it
also logs (stores) the GPS data (default format is shown in section 3.5. TFAC can
modify the format for customer ’s design upon request) to its on-board flash
memory
. The TFAC supplied “
GPSLOGDM.EXE
” is a Win98/ME/2000
application software program that is used to demonstrate and test data logging
functions of

. It will, according to the configuration, start
recording upon power on and stop on running out of storage.
Before using it, users
should turn off or disconnect the TFAC supplied “
