Embodiment Construction
[0061] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0062] First, define the following basic facts, which are known to those of ordinary skill in the art:
[0063] Such as figure 1 As shown, the multi-satellite earth observation task planning problem can be briefly described as: a group of satellites, a group of observation tasks, and the completion of each observation task includes two activities of data collection and data return. A priority is assigned to each observation task; there is a set of available time windows between the ground target corresponding to the observation task and the satellite; a reference time range is used as the start and end time of the task planning. Earth observation satellites need to meet the following constraints: each observation task must be completed within a certain availab...
