Navstar Global Positioning System /GPS/
Abstract
The space-based navigation and time-transfer Navstar Global Positioning System (GPS) provides full time and precise global navigation support for civil and military systems. Prototype equipment tests have shown the GPS to be capable of navigation accuracies an order of magnitude greater than those of existing navigation systems, and bombing accuracies five times better than the best bombing system extant. Attentionis given to the GPS development status and to U.S. Air Force, Navy and Army in-orbit testing and evaluation objectives. When the full 18-satellite GPS constellation is operational, by the end of 1988, 30,000 users will be equipped with receivers, and aircraft, ships, land vehicles and foot soldiers will be able to use the system in order to maximize the coordination of forces. Because the system is passive at the level of the receiver, there will be no danger of betraying one's own positions.
