Kemp use the latest in GPS technology. But how does this technology work?

Modern GPS also known as Global Navigation System (GNSS) utilise twenty four (24) medium orbit satellites. Precise microwave signals are transmitted from the satellites, allowing a GPS receiver to determine its location, speed and direction.

The GPS receiver calculates its position by measuring the distance between itself and these GPS satellites. The distance to each satellite can be calculated by measuring the time delay between transmission and reception of each GPS microwave signal.
