A Comparison of Time Transfer Techniques

Abstract

In the development of timing systems for the Global Positioning System (GPS), a clock ensemble has been installed at the Master Control Station for GPS at Falcon Air Force Station, Colorado Springs, Colorado. A single-frequency, Clear/Acquisition (C/A) GPS receiver is integrated into that system to perform time comparisons with the U. S. Naval Observatory (USNO). Having data from these two sites provided an opportunity to compare different techniques for time transfer and to examine their relative merits and performance. Three basic techniques were examined: common-view, melting-pot, and non-simultaneous common-view. The results and a comparison of the different techniques will be presented.
