|Abstract:||The Soviet Union's global navigation satellite system, CLONASS, currently has nine pre-operational satellites with the full complement of twenty-four satellites available possibly in two years at the present launch rate. Since only a single satellite is required for time transfer to a known location, the potential of Glonass as a disseminator of time and frequency can be evaluated in this pre-operational phase. This paper discusses the timing references available from Glonass and how they are employed in a satellite-to-user time transfer link. Using the Glonass low precision codes, and without making dual frequency corrections, time transfer with Glonass is obtainable to precisions of the order of 100 nanoseconds or better. Data is presented showing the relationship between Glonass system time and UTC (USNO) over an extended period of time. Finally the linking of Glonass system time to UTC(SU) is shown to have been established since late 1988.|
