THE observation of radio signals from Earth satellites has opened up a new field of investigation for the examination of the ionosphere, particularly above the height of maximum ion concentration. The simplest features to observe are the fading-rate of signals resulting from the different phase paths of the ordinary and extraordinary rays, and the Doppler frequency shift.
