PRECISE TIME TRANSFER USING THE STARFIX SYSTEM

Arthur R. Derinis

Abstract:	STARFIX is a newly developed satellite positioning system using conventional C-band geostationary communication satellites. It provides high accuracy positioning for users within the continental United States and offshore areas. STARFIX uses the concept of differential pseudo-range for the positioning task which makes it a natural candidate for precise transfer of timing information between receivers located in the coverage area. At the present time positioning accuracies using STARFIX are on the order of 5 meters RMS or better, with clock offset solution accuracies on the order of 10-15 nanoseconds. This implies continuous time transfer to this accuracy, although the present receivers would have to be modified slightly to resolve the code ambiguity of 6.7 milliseconds. This presentation discusses the STARFIX system as a time transfer device. A global version of the system is also discussed. THIS PAPER WAS NOT RECEIVED, BUT WAS PRESENTED.
