Navigation systems have been crucial to the marine and aviation industries for many years. Today's modern naviation systems are extremely accurate and are now small enough to be fitted almost anywhere - even in your car or in your pocket!. Extensive use of electronic maps and coordination with the Global Positioning System (GPS) of satellites now makes it possible for almost anyone to utilise the incredible benefits these systems provide.

From handheld systems for hikers, in-car computerized street, driving and traffic monitoring systems, to marine emergency beacons and systems that are relied upon by the world's aviation networks, today's modern navigation systems provide unrivaled accuracy and peace of mind for so many people in so many different walks of life.

The Global Positioning System (GPS) consists of a network of satelite transmitters in orbit around the earth. Each of the satellites continuously broadcasts a reference signal. A ground-based GPS reciever can accurately determine its position on the earth if it receives a signal from three or more of these GPS satellites.

GPS provides a cost-effective solution for managing a variety of services including:

• Location reporting and logging,

• Tracking,

• Fleet management,

• Security,

• Field coordination,

• Occupational Health and Safety issues
