1. A method for constructing integrated space-terrestrial network, comprising:
obtaining a target constellation and standardizing a relative motion between each target satellite in the target constellation and earth's surface according to a principle of making a satellite running in a recursive earth-repeat orbit have fixed satellite subpoint trajectories;
obtaining a recursively extended topological structure according to the target constellation;
according to the extended topological structure, dividing geographical cells and obtaining a mapping relationship between the geographical cells and the satellite subpoint trajectories to facilitate network addressing and networking management based on geographical location; and
performing, based on a deployment rule, a recursive incremental deployment according to the extended satellite network topological structure, and realizing integrated space-terrestrial network.
