The U.S built solar panels to allow them to power themselves while they orbit the earth. (Baehr) The solar panels also help direct the satellites orbit. As the satellites orbits the earth, they send out microwave signals to receivers on earth .Then receiver breaks down the signals to find a precise destination or location of more satellites to triangulate your exact location on earth.

(Baehr) Receivers on earth are very common in cell phones, cars, and navigational systems. The receiver picks up a microwave signal from the satellite and uses the data to calculate how far away the satellites are.( Baehr) The receiver, now having the data, does this again with 3 or more satellites. The receiver knows its exact, precise location and stores the information gathered from the satellites signals.
