Although GPS was designed for military use many thousands of civilians make use of it The satellites actually broadcast two signals one is only for military use and the other can be used by both military and civilians Since GPS is passive you only need to receive the signal there are no restrictions on who can use the signal available to civilians GPS technology can be used in a variety of fields besides providing navigation for vehicles on the sea in the air and on the ground GPS applications also include keeping track of where a fleet of trucks trains ships or planes are and how fast they are moving directin gemergency vehicles to the scene of an accident mapping where a city s assets are located and providing precise timing for endeavors that require large scale coordination A DA Ll 9 GLOBAL POSITIONING SYSTEM HI 204111 GPS RECEIVER Pin Assignment 1800 30mm Connectors Mini Din 6 pin male connector o9 Wire 3 6 0 1mm Pocket PC HI 20AIII PS II GPS receiver Can Connecting to a female PS II Connector One end from the female Connector is 12V car charger charging PDA and GPS receiver simultaneously the other end form the female PS II connector is the PDA connector for connecting your PDA For notebook PC use HI 204III PS II can also connect with a PS II to DB9 PS 232 serial cable or USB connector 1 HI 204III Series Introductions
