WebEven when GPS is leveraging more than 4 satellites, it is still doing trilateration, as opposed to multilateration, which GPS does not use. Multilateration should not be confused with trilateration, which uses distances or absolute measurements of time-of-flight from three or more sites , or with triangulation, which uses the measurement of absolute angles. WebA constellation of satellites, called the Global Positioning System, and hand-held receivers allow for very accurate navigation. In this lesson, students investigate the fundamental concepts of GPS technology — trilateration and using the speed of light to calculate distances.
