HOW IT WORKS
- A GPS receiver monitors microwave signals from the orbiting satellites. These signals contain the time of transmission and the position of the satellite. The receiver analyzes these signals by using the travel time of the signals and positions of the transmitting satellites to trilaterate its position. At least four signals are necessary for a good position lock using the GPS system.
- The tracker device is installed with GPS and GPRS based hardware unit which will help in sending and receiving the signals while the tracker is trying to give the tracked information and internal software will function to track and locate the position on the Earth using GPS Technology.
- The system software in the tracker is programmed to monitor the unit being tracked continuously and the tracker will send the tracked information real-time to GPRS stations to facilitate instant tracking. The central server system which maintains the traced information of the tracking vehicle is always in touch with the GPRS station and receives the tracked position of the units being tracked all-time and anywhere.
The proliferation of internet and mobile GPRS connectivity has enabled this tracking system to work with great mobility and great accuracy in tracking, while being very robust and cost effective.
The end-user can review the tracked information by accessing the central Server system where all the tracked information is stored, using web browser. The end-user can also receive the details of the tracked unit’s tracking information by SMS in their mobile phones as tracking details.
