Simulation and analysis on the performances of IGSO satellite constellation

This paper shows us the coverage performance and Doppler shift of the IGSO constellation with 2, 3 or 4 satellites, and then contrasted with the GEO satellite. The IGSO constellation is better than GEO satellite in average elevation angle and multi-satellite coverage. It is concluded after simulation and analysis that the IGSO constellation with 3 or 4 IGSO satellites can provide higher coverage performance for the Chinese areas and nearby, especially communication elevation in high latitude area, just with a small Doppler shift increase. The IGSO satellite constellation can be used more properly as the regional mobile satellite communication constellation.
