Satellite constellations - rosettes with intersatellite links and double surface coverage

two separate moving planes of satellites A rosette satellite constellation with intersatellite links has two locally-separate surfaces of interconnected satellites over ground terminals - one mesh of interconnected satellites ascending south to north, the other mesh descending from north to south.

This layering of redundant meshes affects satellite coverage, the network design for that constellation, and routing of traffic across that constellation. The redundancy of two overlapping mesh fabrics arguably makes the second layer of intersatellite links unnecessary, which is why most low-orbit constellations with intersatellite links use polar Walker star geometries with a single mesh layer, and not Ballard rosettes.

Work related to double surface coverage includes:
