摘　　要：The Combined-GEO-IGSO constellation is the combination of Geostationary Earth Orbit(GEO) satellite and Inclining GeoSynchronous Orbit(IGSO) satellite.The Combined-GEO-IGSO constellation can integrate the advantages of GEO and IGSO to achieve regional coverage.In order to discuss the performances of the Combined-GEO-IGSO constellation,the performances of coverage,elevation,diversity,and transmission are simulated in China and surrounding regions by Satellite Tool Kit(STK).The simulation results show that:the combined constellation can reach higher multi-satellite coverage and higher communication elevation in China and surrounding areas;the Doppler shift,delay,and propagation loss of this constellation have little impact on the system.As regional coverage constellation,the Combined-GEO-IGSO is feasible.The Combined-GEO-IGSO constellation is the combination of Geostationary Earth Orbit （GEO） satellite and Inclining GeoSynchronous Orbit （IGSO） satellite. The Combined-GEO-IGSO constellation can integrate the advantages of GEO and IGSO to achieve regional coverage. In order to discuss the performances of the Combined-GEO-IGSO constellation, the performances of coverage, elevation, diversity, and transmission are simulated in China and surrounding regions by Satellite Tool Kit （STK）. The simulation results show that： the combined constellation can reach higher multi-satellite coverage and higher communication elevation in China and surrounding areas; the Doppler shift, delay, and propagation loss of this constellation have little impact on the system. As regional coverage constellation, the Combined-GEO-IGSO is feasible.
