Study on Orthogonal IGSO global communication satellite constellation

The IGSO (Inclining Geostationary Synchronized orbit) satellite has many unique features to conquer the inherence drawbacks of GEO(Geostationary Earth Orbit) satellite. A group of IGSO satellites could be easily to meet communication requirement. This paper proposes a novel IGSO Constellation called OP-IGSO(Orthogonal orbit Plane IGSO) constellation to realize global communication satellite system. And then, the coverage and transmission performances of OP-IGSO global communication satellite constellation are simulated. The simulation results show that: the OP-IGSO constellation can reach higher multi-satellite coverage and higher communication elevation, the Doppler shift and Doppler shift rate of this constellation have little impact on the system. As global communication satellite constellation, the OP-IGSO is feasible.
