Introduction The GV75W is a compact waterproof GPS tracker designed for a wide variety of vehicle tracking applications.IthasmultipleI/Ointerfacesthatcanbeusedformonitoringorcontrollingexternal devices. Its builtin GPS receiver has superior sensitivity and fast time to first fix. Its triple band WCDMAsubsystemsupportsUMTS/HSDPA850(BandV)/1900(BandII)/2100(BandI)MHzandquad bandGSM/GPRS850/900/1800/1900MHz,allowingtheGV75W'slocationtobemonitoredinreal timeorperiodicallytrackedbyabackendserverandmobiledevices.Itsbuiltin3axisaccelerometer allows motion detection and extends battery life through sophisticated power management algorithms.Systemintegrationisstraightforwardascompletedocumentationisprovidedforthefull featured @Track protocol. The @Track protocol supports a wide variety of reports including emergency,geofenceboundarycrossings,drivingbehavior,lowbatteryandscheduledGPSfix. 1.1. Reference SN
