How Car Tracking Devices Work Tk116

Car tracking devices are relatively simple, yet powerful devices. Most of them use a GPS or Global Positioning System transmitter, as well as cellular technology, plus a network of satellites orbiting around the world. The tracking device receives information from the satellites and then uses this information to determine its current position through trilateration. Three different satellites send their current location and time information to the GPS unit. The tracking device then has to determine the distance between itself and the satellites. Using this information, the device then performs simple calculations to find out its exact location on the earth. The device can also send information to a monitoring center using the cellular networks.

Of course, like any technology, GPS tracking devices do have some downsides. First, the device needs a clear view of the sky to get information from the satellites. Additionally, since cellular networks have limitations, the device may encounter some dead spots, which make them unable to send out signals to the monitoring center.
