A Comparison of Intercontinental Clock Synchronization by VLBI and the NTS Satellite

Abstract

The intercontinental clock synchronization capabilities of Very Long Baseline Interferometry (VLBI) and the Navigation Technology Satellite (NTS) have been compared at the NASA Deep Space Net complexes at Madrid, Spain and Goldstone, California. The VLBI experiments used the Wideband VLBI Data Acquisition System developed at the NASA Jet Propulsion Laboratory. The Naval Research Laboratory NTS Satellites were used with NTS Time Transfer Receivers developed by the Goddard Space Flight Center. The two methods agreed to within about 0.5 microseconds.
