What is GPS?
The Global Positioning System (GPS) is a Global Navigation System that uses approximately 24 satellites orbiting the earth, that transmit signals that are picked up by GPS receivers. The receivers use the data to calculate precise position based on the information from multiple satellites.
The GPS system was originally developed by the United States Defense Department, and is managed by the United States Air Force at an approximate annual cost of $750 million USD.
In 1983, the GPS system was legislated available to the general public as an accurate navigational tool and since then, the popularity of GPS for business and pleasure navigation by ground, sea and air has grown immensely. GPS is also used for map-making, land surveying, commerce and scientific uses as well as providing a precise time reference used in the study of earthquakes and synchronization of telecommunications networks.
