Quizplus · Accepted Answer

GPS determines a location by using the signals from at least 3 satellites, calculating the distance from each based on the time it takes for the signals to reach the receiver. This process, known as trilateration, requires a minimum of three satellites to accurately determine a position in three dimensions (latitude, longitude, and altitude).
