Geosynchronous orbiter tracking by VLBI - Demonstration resultsResults are presented on two experiments which were designed to demonstrate the feasibility of tracking geosynchronous satellites to an accuracy of 5 meters using Very-Long-Baseline Interferometry (VLBI). A communications relay satellite located over the mid-Pacific was observed using baselines between California, Australia and Guam Island. Differential VLBI observations between the satellite and angularly nearby extragalactic radio sources were used to measure the position of the satellite in the plane of the sky. Post-fit residuals to the adjusted trajectory were obtained which correspond to less than 10 meters in one dimension of the satellite position.
