Localization with GPS

The GPS receiver of the GPRS/GPS module is responsible for determining the current location. GPS is an abbreviation for Global Positioning System, a satellite location system which was originally developed by the US Army for military purposes. Nowadays, this system is mainly used for civil applications such as car navigation systems.

24 satellites orbit the Earth at a height of 20,183 km on six orbits and continuously transmit position and time signals. A so-called GPS receiver can receive the signals from up to 12 satellites simultaneously and compares the received time information with its own built-in clock. Since the distance between each of the satellites and the Earth is different, the signal delay times vary too. This is used by the GPS receiver to calculate its position on the Earth’s surface and the height above sea level to an accuracy of only a few metres. In order to do this, the GPS receiver must be able to receive signals from at least four satellites. By installing a GPS receiver in an excavator for example, it is possible to accurately determine its current position.

Track & Find consists of the following components

  • Track & Find DeviceServer
    Gateway software on the GPRS/GPS-terminal. Transmits the position data from the GPS receiver to the Track & Find server

  • Track & Find Server
    Gateway Software on the server

  • Track & Portal
    Visualisation of the data to the Track &amp server on a web-based portal in the internet. Map display e.g. with OpenStreetMap.

Monitoring and control of vehicles and mobile units

Track & Find is a solution to locate and monitor mobile units (vehicles, construction machinery, shipping containers, equipment, etc.).

Each unit to be monitored will be fitted with a combined GPRS/GPS terminal, which transmits the position data received by the GPS through a wireless GPRS data connection to a server, from where the position data can be accessed.
