Own external atmosphere of space vehicles and its influence on parameters of radio signals of on-board radio systems
Abstract
We consider the influence of the solar ultraviolet emission on the photoionization of the working body of drainage systems and microthruster units of a space vehicle, which leads to an increase in the decay of radio-waves of its radio systems. It is necessary to choose the working body of the microthruster units of the space vehicle orienting towards the substances with a low photoionization section (hydrazine, methyl alcohol, etc.). When choosing the working frequencies of radio systems it is necessary to orient oneself towards higher frequencies (hundreds and thousands of megahertz).
