Agile satellite task planning method

The invention provides an agile satellite task planning method, which comprises the following steps of: 1) obtaining a meta-task list of a planning cycle, wherein meta-tasks in the meta-task list are sequentially arranged according to the earliness of starting time, and setting a prospective step length; 2) sequentially selecting one meta-task in the meta-task list as a current task; and 3) making a prospective judgment to the current task by the prospective step length, if the current task comes into conflict with follow-up meta-tasks in the prospective step length, when the priority of the current meta-task is not lower than the priority of the follow-up meta-tasks, deleting the follow-up meta-tasks, and otherwise, deleting the current meta-task, wherein the meta-task list is optimized in advance and the method is applied on the satellite. By adopting the method, conflicts can be rapidly found and eliminated; and by optimizing a satellite task list accordingly, the normal operation of a satellite is ensured
