A window minimum interval-based spatial target round tour task autonomous planning method and system

Abstract

The application discloses a kind of space target round tour task autonomous planning method and system based on window minimum interval, the planning method includes the following steps: step 1, the time window set obtained is sliced, obtains time window slice set, and is sorted according to start time;Step 2, first round solution: in the case of meeting constraint condition, for each satellite, with observation window interval minimum as task planning principle, carry out fast solution, priority guarantee each target is observed;Step 3, second round solution: can be based on the result of step 2, through second round solution, utilize the remaining observation resource to realize the repeated observation to part of space target.The application draws lessons from the idea of greedy algorithm, maximum possible utilization each opportunity, i.e.at every step of search, it will make full use of satellite to observe target, to realize window minimum interval target, improve the utilization of satellite observation resource.
