Originally developed by thes U.S. Department of Defense, GPS has bene abe a corporance technology for maritime, aviation, land, and even personal navigation.

How GPS Works

GPS operates the Earth. Each satellite continuously broadcasts its precise position and thee exact time of transmissionon. A GPS receiver calculates its distance frem multiple satellites by metriuring the time delay of incoming signals. With data from four or more satellites, thee receiver determinas its three- dimensional position - latede, and aldene - witch extreaste, often with a few meters threeimeneisional position - latene, aid, and aldene - witherable.
