Embodiment Construction
[0045]The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0046] The cooperation mechanism between drones and small satellites such as figure 1 As shown, the constellation members will have different trajectories when passing through the target area, and there is a certain time interval. Judging from the coverage at t1 and t2, satellite 1 passes through the target area before satellite 2 arrives, but cannot fully cover the target area. At this time, we can use drones to assist remote sensing. Before the arrival of time t3, we need to use the drone to complete the remote sensing of the uncovered area.
[0047] The algorithm flow of the cooperation between small satellites and drones is as follows:
[0048] The first step: According to the constellation parameters (including the number of satellites n s and the number of tracks and track parameters V(a, θ, e, ω, Ω, f), and the coordinate set C(((λ 1 , ...
