Explanation: 

Detailed explanation-1: -Satellite Navigation is based on a global network of satellites that transmit radio signals from medium earth orbit. Users of Satellite Navigation are most familiar with the 31 Global Positioning System (GPS) satellites developed and operated by the United States.

Detailed explanation-2: -A group of more than 20 satellites make up the Global Positioning System, or GPS. If you have a GPS receiver, these satellites can help figure out your exact location. Why Are Satellites Important? The bird’s-eye view that satellites have allows them to see large areas of Earth at one time.

Detailed explanation-3: -Each satellite emits signals that enable receivers to determine their location and time, according to the FAA. The receiver on Earth computes the time difference between the time of signal reception and the time it was sent by the satellite to compute the distance between the receiver and the satellite.

Detailed explanation-4: -The 24 satellites that make up the GPS space segment are orbiting the earth about 12, 000 miles above us. They are constantly moving, making two complete orbits in less than 24 hours. These satellites are travelling at speeds of roughly 7, 000 miles an hour.
