There are 24 GPS satellites orbiting the earth placed into orbit by the U.S. Department of Defense. GPS was originally intended for military applications, but over time, the system was made available free for civilian use globally. These satellites circle the earth twice a day in a very precise orbit and transmit signal information to a GPS receiver programmed to receive this data anywhere in the world. The receiver needs a clear view of the sky and will not work underground or wherever a view of the sky is not available. The availability and quality of GPS signals may be affected by buildings, natural obstacles, weather conditions and satellite availability.
The TRAQR vehicle tracking device fitted in your vehicle receives this information from a minimum of 3 satellites and uses triangulation to calculate it's exact location - latitude, longitude and movement. It also fetches vehicle information such as ignition status, vehicle moving or parked among other information and prepares all these into a data packet to be sent.
The TRAQR vehicle tracking device then sends this data over the GPRS network of the GSM service provider to their Internet gateway and further over the Internet to the TRAQR Application Server . We have a tie-up with Airtel, Vodafone and BSNL to use their GSM and GPRS network.
