GPS is short for Global Positioning Satellite. It is a world wide navigation system that sends out radio signals from twenty four (24) satellites orbiting the earth.

      Phantom alert GPS uses these satellite signals to define their position within some few meters and to compute the exact speed of your vehicle. The technology involved is highly reliable and used all over the world. The Phantom Alert GPS is capable of tracking twelve (12) GPS satellites concurrently and it requires only three (3) to get a ‘fix’

      Phantom Alert GPS uses the industry standard database of USA, Canada and most of Europe to fix speed camera locations and accident blank spots.
