Webleast 3 satellites, we can determine a 3 dimensional position on the surface of the earth. To teach you the basic concept of how GPS works, we will conduct an exercise to demonstrate trilateration. Trilateration is determining a position by knowing your distance from at least 3 known points. In GPS those known points are the satellites themselves. WebGPS receivers use a constellation of satellites and ground stations to compute position and time almost anywhere on earth. Notice the moving point on the globe and the number of visible satellites. At any given time, there are at least 24 active satellites orbiting over 12,000 miles above earth.
