Best Answer

GPS satellites orbit the earth, around 20,000Kms above us.

They contain very precise atomic clocks which they use to produce a special timing signal which is then broadcast back to earth.

Back on earth, we can use our GPS receivers (Like Sat Nav) to pick up the GPS signals, and by using very clever mathematical algorithms in conjunction with the timing signals we receive from the satellites, calculate our position on the surface of the earth.

Where are GPS satellite signals processed?

GPS signals are processed in the GPS unit and displayed, and they are also processed via three Global Position Satellites. All four units work together and process GPS signals (some to the satellites from the GPS, and some from the satellites to the GPS) to create an accurate position.
