STUDIES OF THE IONOSPHERE USING TRANSMISSIONS FROM ACTIVE SYNCHRONOUS SATELLITES.

Abstract

The exploration of the ionosphere by means of classic methods, i.e., by reflection sounding from the earth's surface or by balloon ascents has been essentially expanded after 1957 by using artificial satellites. Now, for the first time, satellites equipped with transmitters for ultrashort-waves and still higher frequencies were in orbit inside and outside the ionosphere. The investigation of the propagation characteristic of the various frequency ranges revealed several new evidences about the structure and the dynamics of the ionosphere/troposphere. The study investigates the influence of the earth's atmosphere on the propagation of an ultrashort-wave (136 MHz), transmitted from a synchronous satellite keeping its position towards the receiving place practically unaltered.
