Abstract
An inter-layer link design method of multilayer constellations with enhanced service coverage capacity is provided, the method includes: establishing a multilayer satellite network spinning T time slot, and obtaining a coordinate of each satellite in the multilayer satellite network at each time slot under a geocentric coordinate system; establishing an adjacency matrix of each constellation in the multilayer satellite network; establishing a feasible set of inter-layer links between adjacent layers in the multilayer satellite network for each time slot; establishing a globally non-uniform service model according to geographical population distribution, and dividing an earth surface into multiple logical area; obtaining a weight of inter-layer link in the feasible set of inter-layer links at each time slot; establishing an assignment model of inter-layer link according to the weight of inter-layer link; and optimizing an inter-layer link set in the feasible set of inter-layer links to obtain a target inter-layer link set.
