The most promising and fully operational GPS Global Positioning System is a navigation system based on a group of 24 satellites developed by U. Department of Defence. Every satellite sends data to the receiver in the form of signals, having some information about satellite and orbital information. This paper aims to discuss the potential of GPS as constantly global communication medium and gives insights in terms of its business and military applications.

Global Positioning System

Return to the Main GIS page. What is GPS? GPS, which stands for Global Positioning System, is a radio navigation system that allows land, sea, and airborne users to determine their exact location, velocity, and time 24 hours a day, in all weather conditions, anywhere in the world. GPS is used to support a broad range of military, commercial, and consumer applications. The satellites are spaced so that from any point on earth, four satellites will be above the horizon.

Each satellite contains a computer, an atomic clock, and a radio. With an understanding of its own orbit and the clock, the satellite continually broadcasts its changing position and time. Once a day, each satellite checks its own sense of time and position with a ground station and makes any minor correction. On the ground, any GPS receiver contains a computer that "triangulates" its own position by getting bearings from three of the four satellites.

The result is provided in the form of a geographic position - longitude and latitude - to, for most receivers, within a few meters. If the receiver is also equipped with a display screen that shows a map, the position can be shown on the map. If you are moving, your receiver may also be able to calculate your speed and direction of travel and give you estimated times of arrival to specified destinations.

Global Positioning System – Working and its Applications

The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. The GPS provides critical positioning capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver. The GPS project was started by the U. Department of Defense in , with the first prototype spacecraft launched in and the full constellation of 24 satellites operational in
