GPS tracker Testing

The Global Positioning System (GPS) serves as a universally accessible, satellite-dependent radio navigation system designed to precisely determine the location of your vehicle. Through a network of orbiting satellites, GPS transmits signals detectable by receivers installed in vehicles, enabling them to ascertain their position with exceptional accuracy.

Each GPS satellite emits radio signals utilized by GPS receivers to calculate the vehicle’s location on Earth’s surface, converting this data into geodetic latitude, longitude, and velocity. To pinpoint the vehicle’s position, a receiver requires signals from a minimum of three GPS satellites. It’s important to note that GPS receivers, commonly integrated into vehicle tracking systems, are solely capable of receiving data from GPS satellites and lack the ability to transmit information back to satellites or any other source. Therefore, a GPS-based system can determine its location but cannot relay this information to a central control room independently. To facilitate communication, such systems typically rely on GSM-GPRS cellular network connectivity, facilitated by an additional GSM modem/module.

Conversely, a Geographical Information System (GIS) comprises software featuring meticulously crafted, comprehensive maps of cities, detailing longitude and latitude information for each location, street, junction, and address. While a GPS-GSM system offers longitude and latitude coordinates of the vehicle, GIS software, if properly developed, can provide precise or nearby address details corresponding to the vehicle’s location.
