and under the condition that the task to be executed with the highest priority is determined to have completed the distribution of the satellite resources, judging whether the satellite resources to be distributed still exist, and under the condition that the satellite resources to be distributed still exist, distributing the rest satellite resources for the task to be executed with the low priority to obtain task arrangement information of the task to be executed with the low priority.
