Pronunciation: [nˈavstɑːɡps] (IPA)
NAVSTAR GPS (Navigation System with Timing and Ranging Global Positioning System) is a satellite-based global navigation system that provides accurate positioning, velocity, and timing information to receivers on or near the Earth's surface. It is a space-based radio-navigation system that allows users to determine their precise location and time in any weather condition and at any location on or near the Earth.
NAVSTAR GPS operates via a constellation of at least 24 satellites in medium Earth orbit (MEO), with an orbital altitude of approximately 20,200 kilometers (12,550 miles) above the Earth's surface. These satellites continuously transmit timed signals in radio frequency bands that can be received by GPS receivers. The system operates by using a process called trilateration, where signals from multiple satellites are combined to determine the receiver's three-dimensional position.
NAVSTAR GPS has a wide range of applications, including navigation and positioning for a variety of military, civilian, and commercial uses. It is extensively utilized in aviation, maritime, land-based transportation, surveying, mapping, and outdoor recreational activities. Additionally, it aids in time synchronization for various industries, including telecommunications, scientific research, and financial transactions.
The development and maintenance of the NAVSTAR GPS system is primarily overseen and managed by the United States Department of Defense. GPS receivers, which can be found in numerous devices such as smartphones, cars, and handheld navigation systems, utilize the transmitted signals from the GPS satellites to accurately determine precise location, velocity, and time information.
