Embodiment
[0069] Aiming at a plurality of discretely distributed ground targets set in the global range, the present invention designs a low-orbit satellite orbit that can bring all the ground targets into the range of satellite reconnaissance, and can periodically reconnaissance the ground targets. Then, aiming at the shortest revisit time interval of ground targets, the optimal design of the time for each satellite in the constellation network to fly over the ground targets is carried out, and the optimal low-orbit satellite network structure for fast revisiting discrete targets is obtained. Type scheme.
[0070] (1) Randomly select multiple ground targets discretely distributed around the world
[0071] Randomly select 12 ground points discretely distributed around the world as reconnaissance targets, and the latitude and longitude distribution of each ground target is shown in Table 1:
[0072] Table 1 Randomly selected locations of 12 discretely distributed ground targets around t...
