Global Positioning System (Topical Term)

Work cat.: International Symposium on Precise Positioning with the Global Positioning Systems (1st : 1985 : Rockville, Md.). Proceedings, First International ... c1985: p.1 ("The Navigation Satellite Timing and Ranging Global Positioning System (NAVSTAR GPS) is under development by the US Dept. of Defense as a worldwide, all-weather navigation and timing system. When fully deployed, GPS will allow suitably equipped users to determine, instantaneously (or nearly so), their position and velocity. Furthermore, users with specially equipped receivers and longer observing periods will be able to determine absolute point positions and relative positions with greater accuracy, at lower cost, and in less time than any other method available.")
