Real Time Navigation


What is Real Time Navigation?
Using atomic clocks and location data, each satellite continuously broadcast the time and its position. A GPS receiver receives these signals, listening to three or more satellites at once, to determine the x, y, z coordinates of users position on earth. The GPS signal will provide a civilian user an accuracy of better than 15 meters (50 feet).
