Yes. Global positioning satellite systems pinpoint their position using time and distance calculations received from the various GPS satellites. If a GPS systems pinpoints a location at a certain time, and pinpoints a different location at a certain time later, all that is needed to determine how fast the GPS got from the first point to the second is simple math.
Global Positioning Systems (GPS) use trigonometry. There are a number of satellites orbiting the earth. The GPS uses the time signals sent by these satellites to establish the distance to the satellites. Trigonometry is then used to find the location of the GPS unit.
