Abstract: In this paper an algorithm for design of the radio channel for satellite TV systems of first and second generation is presented. The algorithm allows taking into account the parameters of the repeater, satellite radio line and receiver, as well as the methods used for channel coding and modulation. The results of the research on the impact of ERP, the channel bandwidth, intensity of the rainfall, the size of the receiving antenna, noise ratio of LNC, earth position of the receiving antenna and others on the carrier to noise ratio on the receiver input are presented.
