An autonomous mission planning method for earth remote sensing satellites with multiple planning modes

Abstract

An autonomous mission planning method for earth remote sensing satellites with multiple planning modes. First, the Earth observation targets to be planned are selected, so that a task set to be plan is obtained, and the Earth observation targets included in the planning task set are preprocessed, and then according to the task set to be planned after preprocessing, a long-period pre-coarse missionplan scheme sequence is obtained by carrying out long-period pre-coarse mission planning, and finally, short-period local window rolling planning is carried out on the long-period pre-coarse missionplanning scheme sequence according to the real-time updated environmental information and satellite maneuverability, and the emergency mission dynamic planning is carried out according to the high-priority ground emergency observation mission. The long-period pre-coarse mission planning scheme sequence is obtained by carrying out long-period pre-coarse mission planning.

Problems solved by technology

However, the shortcomings of the above existing methods are mainly reflected in: (1) The existing remote sensing satellite autonomous task planning methods do not consider the different requirements of different source tasks for the real-time and optimization goals of the planning method, and generally only use a certain method to carry out the task. Therefore, the solution to the mission planning problem close to engineering applications with multi-source mission input, satellite and environmental changes is not effective; (2) the existing remote sensing satellite autonomous mission planning methods are generally designed according to the way realized on the ground , does not consider the limitations of on-board computing resource constraints on the realization and operation of autonomous mission planning methods, and the engineering applicability is general
