Losses of Energy Potential on Communication Lines Space Apparatus - Earth Station

The energy losses of radio signals on the radio communication lines between the spacecraft and the Earth are considered, taking into account various natural factors that affect the conditions for the propagation of radio waves. It is shown that the ionosphere at frequencies above 5 GHz does not lead to a noticeable attenuation of radio signals, affecting only the polarization of waves and the group delay of signals. Expressions are given for the numerical determination of the attenuation of the radio signal during rains, as well as during dust storms along the communication path.
