Analysis of the joint operation of intersatellite and radio-navigation services in the 32-33 GHz band

An analysis is presented of the level of interference from ground and air radio-navigation intersatellite servicing systems. It is shown that an intersatellite communications service in geostationary orbit and a radio-navigation service can be operated jointly within certain limitations. In order to avoid interference from the radio-navigation service, it is important to disperse the energy of the carrier signal used in the intersatellite communication service with a level of not less than 10 dB. The maximum permissible power density of the interference at the surface of the earth from an intersatellite communication link must not exceed -163 dB W/sq m MHz, and the gain of the receiving antenna equipment for the radio-navigation equipment must not be greater than 60 dB.
