Abstract:	The NAVSTAR/Global Positioning Systems (GPS) will provide extremely accurate three-dimensional position and velocity information to users anywhere in the world. The position determinations are based on the measurement of the transit time of RF signals from four satellites of a total constellation of 24. Accuracies on the order of 10 meters may be anticipated. This paper discusses the basic technique by which the system operates, the navigation signal, the measurement of the transit time, error sources, accuracies, and other characteristics of the system.
