Detailed explanation-1: -What is the GPS Satellite System? 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.
Detailed explanation-2: -To accomplish this, each of the 31 satellites emits signals that enable receivers through a combination of signals from at least four satellites, to determine their location and time. GPS satellites carry atomic clocks that provide extremely accurate time.
Detailed explanation-3: -It takes four GPS satellites to calculate a precise location on the Earth using the Global Positioning System: three to determine a position on the Earth, and one to adjust for the error in the receiver’s clock.
