This system consists of three segments: the space segment, the control segment, and the user segment. The U. Space Force develops, maintains, and operates the space and control segments. GPS satellites provide service to civilian and military users.
Global Positioning System

An introduction to the global positioning system and its applications Abstract: The global positioning system GPS was declared operational for civilian users in December Although this declaration may have political importance, it is likely to have little impact on the ever increasing numbers of civilian users.
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. It focuses on the architecture of GPS, its working, changing signal conditions and discusses its technical applicability and uses current advanced applications of GPS like vehicle tracking, location-based services as a case study.
Uses of GPS: What are GPS Systems used for?
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 Originally limited to use by the United States military, civilian use was allowed from the s following an executive order from President Ronald Reagan.
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.

The technical and operational characteristics of the GPS are organized into three distinct segments: the space segment, the operational control segment OCS , and the user equipment segment. The GPS signals, which are broadcast by each satellite and carry data to both user equipment and the ground control facilities, link the segments into one system. Figure briefly characterizes the signals and segments of the GPS. The GPS constellation consists of 24 satellites arranged in 6 orbital planes of degree inclination, 20, kilometers 12, miles above the Earth. Each satellite completes one orbit in one-half of a sidereal day and, therefore, passes over the same location on earth once every sidereal day, approximately 23 hours and 56 minutes.
How GPS System Works?
GPS systems are extremely versatile and can be found in almost any industry sector. Today, GPS is used to map forests, help farmers harvest their fields and airplane pilots navigate on the ground or in the air. Positioning systems are integral to military applications and for emergency crews to locate people in need of assistance. GPS technologies are often working in many areas that we do not normally consider.
