Abstract: Objectives: Laser inter-satellite link (LISL) of the navigation constellation has been assigned
with constraints of the inter-satellite visibility, the number of laser terminals and the link system to realize
efficient inter-satellite ranging and communication with ground stations. Methods: According to the laser
link system, each link period includes two states, transition state and steady state. The transition state com⁃
pletes the link switching and reconstruction, and maintaines a static link topology when entering the steady
state. Based on the static processing, a multi-objective assignment model of steady-state LISL of naviga⁃
tion constellations is established. A multi-objective optimization algorithm for link topology based on non-
dominated sorting genetic algorithm-II (NSGA-II) is proposed. By introducing the edge connectivity con⁃
straint of the transition topology into the steady-state optimization model, the whole network connectivity
