Introduction 

The  GV75W  is  a  compact  waterproof  GPS  tracker  designed  for  a  wide  variety  of  vehicle  tracking 
applications.  It  has  multiple  I/O  interfaces  that  can  be  used  for  monitoring  or  controlling  external 
devices.  Its  built‐in  GPS  receiver  has  superior  sensitivity  and  fast  time  to  first  fix.  Its  triple  band 
WCDMA subsystem supports UMTS/HSDPA 850 (Band V)/1900 (Band II)/2100 (Band I) MHz and quad 
band GSM/GPRS 850/900/1800/1900 MHz, allowing the GV75W's location to be monitored in real 
time or periodically tracked by a backend server and mobile devices. Its built‐in 3‐axis accelerometer 
allows  motion  detection  and  extends  battery  life  through  sophisticated  power  management 
algorithms. System integration is straightforward as complete documentation is provided for the full 
featured  @Track  protocol.  The  @Track  protocol  supports  a  wide  variety  of  reports  including 
emergency, geo‐fence boundary crossings, driving behavior, low battery and scheduled GPS fix.
