The Place and Capabilities of Modern Doppler Systems for Subsonic and Supersonic Aircraft 670328
This paper describes the considerable advances made in the Doppler radar and Doppler navigation system state-of-the-art since the early 1960's. A detailed comparison is made between the earlier Dopplers and today's vintage. A new Doppler-inertial system, currently being developed for the military, is described and where pertinent compared to a comparable pure inertial system. The analysis concludes that using this approach adequate navigation accuracy can be achieved for subsonic and supersonic transports at approximately one-third the cost of a comparably reliable inertial installation.
