Evaluation of a Very Low Frequency Navigation System.

The result of 32 flights using existing phase-stable very low frequency (VLF) communication stations for air navigation are presented. The Global Navigation System's (GNS-200) VLF system was used to provide course deviation, distance-to-go, and groundspeed. Local flights, in range of the Extend...

Description
Summary:The result of 32 flights using existing phase-stable very low frequency (VLF) communication stations for air navigation are presented. The Global Navigation System's (GNS-200) VLF system was used to provide course deviation, distance-to-go, and groundspeed. Local flights, in range of the Extended Area Instrumentation Radar (EAIR) located at the National Aviation Facilities Experimental Center (NAFEC), were made in an Aerocommander aircraft. Flights in a Convair 880 were made to the West Coast, Bermuda, Caribbean, Arctic Circle, and across the North Atlantic to Europe and return. VOR and DME data were used for position reference on the flight to California. The LTN-51 inertial navigation system display was photographed at regular intervals for use as a reference on oceanic flights. The National Aeronautics and Space Administration (NASA) tracking radar at Bermuda was used for reference for flights in the vicinity of Bermuda.
