A remote sensing satellite energy balance constraint analysis system and method

Abstract

The present invention relates to a remote sensing satellite energy balance constraint analysis system and belongs to the technical field of satellite task simulation. The complex task planning and the complex configuration of a high-resolution remote sensing satellite and the dynamic analysis of the energy balance of the satellite are enabled, wherein the satellite has rapid attitude maneuvering requirements. According to the technical scheme of the invention, the satellite discharge depth of the satellite at each load task ending moment is calculated, and then the number of turns required for the energy balance of the satellite at the ending moment of each solar irradiation region is obtained. Meanwhile, according to a discharge depth safety threshold, whether the task of the satellite can meet the energy constraint condition or not is judged. For example, on the condition that the satellite can meet the energy constraint condition, an energy analysis result is outputted. Otherwise, the calculation result is returned to an upper-level task planning system. According to the energy balance condition of each turn and the discharge depth at each task ending moment, the re-adjustment is conducted and a new task planning is input for calculation.

Description

technical field [0001] The invention relates to a remote sensing satellite energy balance constraint analysis system, which belongs to the technical field of satellite task simulation, and aims at the complex task planning and complex configuration of high-resolution remote sensing satellites with fast attitude maneuvering requirements, and dynamically analyzes the energy balance of the satellites. Background technique [0002] my country's traditional remote sensing satellites have poor attitude maneuverability, and the number of satellite single-track imaging tasks is small. The satellite's attitude maneuverability limits the number of single-track task executions. Therefore, the constraint of satellite energy on tasks does not become the main limitation of satellite task realization capabilities. The energy constraint of traditional satellites adopts an extensive static constraint method. According to the maximum side swing angle of the satellite (direction away from the s...

The existing digital modeling and simulation results of remote sensing satellites are mainly used for static parameter modeling and simulation of specific satellite states. In the application of modeling and simulation, satellite development and design verification or visual display are mainly used, and energy constraints cannot be dynamically calculated according to imaging tasks, thus Improve the satellite's on-orbit mission execution capability

The invention patent "Dynamic Power Balance Analysis System of Lunar Exploration Vehicle" (ZL201310108746.X) proposed by Zhang Xiaofeng, Chen Qi, etc. can analyze the energy consumption of satellites at different stages for lunar exploration missions, but cannot analyze the energy conditions of satellites according to satellite attitude maneuver tasks. Carry out dynamic analysis, and at the same time, the system does not consider the impact of the complex configuration of the satellite on the solar wing shading on the energy on the star, and cannot meet the task requirements of remote sensing satellites for dynamic and accurate analysis of the satellite's energy balance under complex mission planning and complex configuration conditions
