Comparison of Continuously Filtered GPS Carrier-Phase Time and Frequency Transfer With Independent Daily GPS Carrier-Phase Solutions and With Two-Way Satellite Time Transfer

Abstract

Several different modes of precise time transfer are currently in use or under development. These include GPS common view, two-way satellite time transfer, and GPS carrier phase. The U.S. Naval Observatory has accumulated several years of data analyzing these techniques with side-by-side comparisons over short, intermediate, and long baselines. Each technique can offer something to the mix, and we use the comparisons to discuss the strong points and weaknesses of each one.
