Aimed at the issue of co-channel interference estimation in the Geostationary Satellite Orbit (GSO) system layout, the interference assessment scenarios were designed with the global distribution of earth stations and satellites for downlink and uplink and the integrated impact of beam service characteristics for multiple links. The interference estimation and analytical calculation models for the global distribution of the GSO system were established. An evaluation method based on interference function extremum was proposed. By establishing the random distribution set of the interference earth stations and the function of the interfered system, combined with the global terrain data, antenna beam parameters, and electromagnetic wave propagation model provided by International Telecommunication Union (ITU), the method could realize the quantitative calculation and analysis of satellite orbital and earth station layout between two GSO systems. The method was applied to co-directional downlink and uplink interference scenarios for quantitative calculation, with GSO satellites at 47°E±6° and earth stations at the (23°N, 26°E) for downlink, and GSO satellites at 26°E±6° and earth stations at the (23°N, 26°E) for uplink. The results show that the interference-to-noise ratio value is -12.29 dB with 2° orbital interval, and the error is 0.7% with the limit -12.2 dB specified in the ITU Recommendation, which verifies the effectiveness and feasibility of this method. The method can also calculate the interference distribution of GSO system in any angular interval and global deployment scenario, which has certain reference significance for making interference assessment and avoidance measures.
