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.")

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radio navigation system owned by the United States Space Force and operated by Mission Delta 31. It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephone or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls, and maintains the GPS system, it is freely accessible to anyone with a GPS receiver.
