Abstract:

The report summarizes the work performed at DOTTSC on the TimeFrequency ATC System study project. Principal emphasis in this report is given to the evaluation and analysis of the technological risk areas. A survey and description of proposed TF system is included. The technical risk areas include the effects of multipath on signalling over radio links. Material is presented which bears on the comparative analysis of TF with alternative technologies, including satellite and beacon-based system concepts. It is concluded that the most critical problem areas requiring further study are a multipath effects on TF systems, and b systems operability under non-ideal conditions leading to graceful degradability.
