The Beacon Technique as Applied to Oblique Incidence Ionosphere Propagation

A method is shown for determining transmission time for each mode of transmission via the ionosphere and obliquely incident thereupon. The method makes use of an interrogator-responsor at the transmitting site and a beacon transpondor at the receiving site. Limitations of the method are discussed and preliminary results are shown for a 1,500-mile, north-south path.
