Explaining the GPS Work

Question

Explain how does the GPS Work?

Answer 1

Three different parts make up the Global Positioning System. The first segment of system contains the 24 satellites, orbiting 20,000 km above the Earth in the 12 hour circular orbits. This means that it takes every satellite 12 hours in order to make a complete circle around Earth. For make it sure, that they may be detected on the Earth’s surface from anywhere, the satellites are divided into 6 groups of four. Every group is allocated a different path to follow. This generates six orbital planes that completely surround the Earth.
