MODELS OF THE GLOBAL SATELLITE COMMUNICATION-SYSTEMS AND METHODS OF THEIR ANALYSIS

The paper describes the global satellite communication systems aimed t o provide the two-channel communications for the users at any time for any point of the Earth and to provide the exchange of the data betwee n the satellites. It also discusses the method of the analysis of such systems made to determine the stable two-channel communications or th e communications which require minimum reorientation of the antennae, The approach shown in the paper makes possible to synthesize the struc ture of the two-channel satellite communications which is stable for t he given period of time.
