Based on Globalstar and Odyssey systems, which are two well-known Walker delta type constellations, ISL networks are constructed and dynamic characteristics of inter orbit links are analyzed. Pointing, acquisition and tracking (PAT) subsystem on-board has close relationship with azimuth angle, elevation angle and ISL length whose variance is important to transponder power control system. Multi-coverage...
Polar and quasi-polar orbit constellations have "seams" between counter-rotated orbits, and ISLs need switch off above the polar regions. Satellite communication networks made up of Walker constellations have steady topology and good ISL performance. Adaptive routing strategy uses path-weight instead of delay or delay jitter as a criterion to select a path under three service models. Numerical...
Walker delta type constellation is an excellent candidate to compose non-geostationary orbit satellite communication networks. LEO and MEO satellite networks composed by Walker delta constellations have many excellent characteristics respectively and the elevation angle, azimuth angle and length of ISLs in these two systems are studied especially. Using different routing strategy in order to fulfil...
