An Internet-Based Global Differential GPS System, Initial Results

Ronald J. Muellerschoen, Willy I. Bertiger, Michael Lough, Dave Stowers and Danan Dong

Abstract:	Using a network of 15 global GPS receivers, GPS data is returning to JPL via the open Internet to determine the orbits and clocks of the GPS constellation in real-time. Corrections to the broadcast orbits and clocks are currently communicated in real-time to the user over the open Internet via a TCP server. Tests of user positioning show real-time RMS accuracy of ~10 cms RMS in horizontal and < 20 cms RMS in the vertical.
