This article reprints a presentation at the NMEA [National Marine Electronics Association] Annual Meeting, 1988. The author believes that although the timing of the acceptance of the Global Positioning System (GPS) by the marine community may be debatable, the eventuality of that acceptance is certain. Many of the questions and issues that will arise will concern the accuracy of GPS. This paper is intended to provide a non-technical reference on this subject of GPS accuracy for marine navigation. It encompasses a review of the general concepts of position and position accuracy; a discussion of some commonly used measures of accuracy; and a brief description of the GPS measurement process, with emphasis on accuracy issues and sources of error.
