Global Positioning System (GPS) trackers are portable devices that allow fleet managers, parents, and vehicle owners to monitor and track their cars and trucks. Real-time GPS car trackers can provide instant speed and location data, while less expensive options store the information for later use. Some GPS vehicle trackers allow you to set real-time alerts that go off when a driver exceeds the speed limit or strays from a designated area.
How does a GPS tracker work?
GPS tracking uses a network of satellites to determine the location of a device designed for that purpose. The basic idea is that a GPS tracker uses trilateration to determine its physical location based on its distance from three GPS satellites. This is the same technology used by a portable or in-car navigation system.
The difference between a GPS tracker and a car navigation system is that the navigation system provides you with your location and driving instructions. A tracker, on the other hand, keeps a record of your driving behavior or broadcasts its location in real time.
When a GPS car tracker can broadcast its location, it typically uses the same technology as your cell phone to make calls or connect to the internet. That’s why some GPS car trackers require a monthly subscription fee.
