GPS Vehicle Tracking Systems
How does GPS work? To be able to work out a two dimensional position (longitude and latitude), and follow a car's movements, a GPS receiver must lock on to the signals of not less than three space satellites. GPS tracking devices pick up these signals from satellites in orbit around the Earth. These GPS satellites are powered by the sun's energy.
As well as helping with navigation, GPS devices also meet another basic need for vehicle drivers - security. Owners of expensive cars can put a GPS tracker in the car, and, if the car is stolen, turn the device on in order that the car's exact position can be tracked.
Over the last decade, ever more business fleet owners, emergency services, as well as family car owners, have come to depend on the massive advantages of GPS technology.
