The Global Positioning System, Navstar, is an advanced satellite-based navigation system which is currently under development and evaluation in the United States of America. Progress has been very fully reported in the open literature and a definitive paper on the concept has in fact been published in the Journal of Navigation. The concept has now been experimentally validated and much of the evidence which supports this validation has in turn been published. The impact of Navstar on navigation in the period beyond 1985 is potentially very great indeed in that it offers, worldwide, navigation capability to surface and aerospace users of a standard of accuracy combined with continuous availability which is currently associated only with short-range aids. This paper has the objective of presenting (a) a general introduction to the physical principles on which Navstar is based, followed by (b) a survey of its potential relevance to the operational needs of various classes of user. Finally there is some more speculative matter in the form of (c) a discussion of the potential impact of successful implementation of Navstar on current and projected future navigation systems.
