In LEO satellite constellation communication system, the routing strategy becomes a big challenge for the movement between satellites. According to researching on the 24/3/1 walker satellite constellation with inter-orbit ISLs and intra-orbit ISLs, two routing optimization scenarios based on ISL state and topology snapshot are suggested. At the same time, some valuable conclusions are provided according...
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...
