Abstract:The theoretical reliability of digital data transmission via high frequency radio is examined for typical air traffic routes in the Atlantic and Pacific areas to assist the U.S. Department of Transportation in the evaluation of a system for improving air traffic control over ocean areas. The expected performance of a reference high frequency data transmission system of 1200 bits per second with a permissable error rate of one in a thousand binary error is expressed as a percentage of time that a given theoretical reliability will be equaled or exceeded. The expected performance of air-to-air HF systems is also considered, and it is concluded that these systems should work for the reference communication system out to the line-of-sight range of about 800 km for high-flying aircraft.
