Global Positioning System (GPS) technology is changing the way we work and play. With a GPS receiver, you can know your location. This amazingly useful technology has thousands of applications, from navigating unfamiliar roads to re-locating the perfect fishing spot.
How does it work?
GPS is made possible by a network of at least 24 satellites that circle the earth twice a day from about 19,000 kilometres above us. Each satellite moves at 11,000 kilometres per hour while continuously transmitting time-based signals to earth that indicate the GPS devices location.

How is GPS used?
The possible uses for GPS technology are as unlimited as your imagination. It is already being used in balloons which monitor the hole in the ozone layer, for tracking endangered species and, attached to buoys, keeping a trace on major oil spills during clean up operations.

The future of GPS and devices
As GPS technology advances, and navigation hardware and software improves, there’s a lot to look forward to. New GPS chips promise near-instantaneous positioning information, and new applications promise to integrate GPS technology into everything from travel guides to automobile cruise control systems.
