Abstract:

This paper describes the functions, requirements, and objectives of the Time Distribution System TDS. It should be pointed out that the WAAS TDS has not yet been developed because it is a component of the final phase of WAAS development. However WMS Phase 1 allows for the inclusion of the TDS into the WAAS if it is developed before the final phase of WAAS. The TDS will be located at the U.S. Naval Observatory USNO. It will be used to provide the offset data between WAAS Network Time WNT and Coordinated Universal Time UTC. The offset data will then be passed on to the WAAS Master Station WMS for transfer to the Geostationary Uplink Station GUS and broadcast to users of precise time through the WMS Signal-in-Space SIS.
