The Propagation of Very Short Radio Waves through the Ionosphere and the Investigation of Ionospheric Models.
Abstract
The Research Note deals with propagation phenomena of very short radio waves in the ionosphere as they occur in radio links between earthbound stations and satellites. It is shown how the propagation of radio waves is affected by the ionosphere and how radio range measurements have to be treated in order to obtain the geometrical distance between the terminals of the radio link. Radio waves of several frequencies (225 MHz, 420 MHz, 450 MHz, and 1600 MHz) are quantitatively discussed, because these frequencies relate to the Sequential Collation of Range (SECOR) System and to the proposed Defense Navigation Satellite System (DNSS).
