Detailed explanation-1: -A global positioning system (GPS) is a network of satellites and receiving devices used to determine the location of something on Earth. Some GPS receivers are so accurate they can establish their location within 1 centimeter.
Detailed explanation-2: -What is GPS? The Global Positioning System (GPS) is a U.S.-owned utility that provides users with positioning, navigation, and timing (PNT) services.
Detailed explanation-3: -Using the Global Positioning System (GPS), every point on Earth can be given its own unique address-its latitude, longitude, and height. The U.S. Department of Defense developed GPS satellites as a strategic system in 1978.
Detailed explanation-4: -Multiple satellites beam signals at the speed of light toward Earth, and your device receives the signals at slightly different times, based on how far away each satellite is from your location. These times can be used to calculate the differences in distance from each satellite to determine your location on Earth.
