Abstract

The embodiment of the invention provides an application-oriented heterogeneous constellation space-ground integrated task planning method and device, wherein the method comprises the steps of synthesizing an observation task demand; collecting the basic parameters and real-time state information of each satellite in the heterogeneous constellation; configuring the measurement and control and datatransmission resources of executable tasks; giving a time function of each satellite orbit position by utilizing accurate orbit prediction; sorting all the sub-tasks, processing conflicts among the sub-tasks, and judging whether a conflict relationship between the current to-be-added observation sub-task and each observation sub-task in the current observation sub-task set meets constraints or not; carrying out downlink scheduling; scheduling an observation data route by adopting a greedy algorithm; and generating a task planning scheme, estimating the duration of each observation and data transmission activity, the conversion time of satellite attitudes and the change of satellite related state parameters, and generating a task arrangement scheme containing the observation activities andthe data transmission activities.

Description

technical field [0001] The present invention relates to the field of aerospace mission planning and performance evaluation, and in particular, relates to an application-oriented heterogeneous constellation space-terrestrial integration mission planning method and device. Background technique [0002] With the continuous enrichment of my country's space-based earth observation system, the number of satellites in orbit is increasing year by year, the orbit deployment is gradually improved, and the types of loads are gradually diversified. It has been successfully applied in many application fields such as agriculture, water conservancy, ocean, meteorology, and land resources. . However, under the construction model driven by industry users, the current earth observation satellites or constellations are mostly oriented to specific users, and provide specific business earth observation satellites in the operation mode of single satellite, multi-satellite network or small constell...
