GPS (Global Positioning System) is the technology that is behind many tracking and navigation systems. Tracking systems use GPS for its accuracy and reliability.
GPS was, and continues to be, developed and maintained by the United States military. Development began during the 1960’s but the system wasn’t fully operational until 1995. The system has between 24 – 32 satellites orbiting the Earth. The orbit paths have been arranged in such a way so that from any location on the planet a GPS antenna is able to receive signals (providing the antenna has a clear line of sight to the sky), from at least 4 satellites.
GPS Satellites continually transmit time signals; a GPS antenna receives these signals from multiple satellites and uses the data to calculate its current global position in longitude, latitude and altitude.
Vehicle tracking devices use GPS to calculate their position, speed and direction. This data is then sent back to the user via the mobile phone data network. The tracking data is stored by a secure server which is then made available to the user via the tracking application.
The application provides a range of reports and real time data tools to help managers control their fleet and reduce fuel prices.
