Real-Time Position Determinations Using the GPS T14100/GEOSTAR Receiver.

Abstract

The NAVSTAR Global Positioning System is a worldwide, all-weather, satellite positioning system capable of high accuracy real-time position determinations. The Applied Research Laboratories (ARL:UT), in conjunction with the Naval Surface Weapons Center (NSWC/DL) and other government agencies, conducted geodetic field tests of a government sponsored prototype receiver, the TI4100/GEOSTAR, in March 1984. Data were acquired from four satellites by three receivers, with antennas located at known stations, over approximately six-hour periods each day. Based on real-time solutions acquired on March 1, 8, and 9, 1984, absolute point position determinations have an average discrepancy of 7.5 meters with a one sigma repeatability of less than a meter. Relative positions were determined to an average relative accuracy of 1:9,700 for distances of 14 to 26 kilometers. Originator supplied keywords include: Global Positioning System; Geodetic positioning; Satellite Locating System GEOSTAR Receiver; and Real-Time Positioning.
