Orbit and Troposphere Results of a Real-Time Prototype WADGPS System

Ronald J. Muellerschoen, Willy I. Bertiger, Larry J. Romans

Abstract:	Implementation and results of a real-time GPS orbit correction process for WADGPS is presented. The current processing utilizes data from SATLOC’s North American reference network. It has been in operation since November 13, 1996. Every 15 minutes it processes the accumulated data from the previous 15 minutes. The GPS horizontal orbit accuracy over this network is 1.2 m rms. The horizontal orbit accuracy over the north latitudes of the Western hemisphere 2.0 m rms. Augmenting this network with 6 IGS sites including Hawaii, Alaska, aud Bermuda, reduces the horizontal orbit accuracy over the north latitudes of the Western hemisphere to 1 meter rms. The zenith troposphere errors from this processing are 1-2 cm rms.
