Description

Technical Field

[0001] The present invention relates to the technical field of spacecraft system simulation, and in particular to a virtual-real combined remote sensing satellite mission scene simulation system and method. Background Art

[0002] Satellite installation tests are subject to environmental conditions and constraints such as coordination units, equipment, and funding. The test process may also cause serious damage to the equipment, resulting in complex organization and high costs. In satellite ground test verification tasks, real satellites cannot be used for repeated iterative verification and optimization. Engineering-level remote sensing satellite models rely on professional analysis methods to model physical mechanisms or constraints, and can access real software on board to perform fine-grained simulations of key subsystems such as satellite integrated electronics, energy, propulsion, attitude and orbit control, onboard data processing, intersatellite transmission, and digital transmission that are close to the real system, and perform ground equivalent verification of onboard software. Using engineering-level remote sensing satellite models to simulate mission scenarios can analyze and evaluate the performance of various equipment, shorten the test verification cycle, reduce test verification expenses, and optimize the iterative process of solution design.

[0003] The application scenarios of remote sensing satellites often involve multi-field and multi-type equipment. In order to build mission scenarios that are close to reality, it is necessary to build full-factor and complete equipment simulation scenarios, introduce multi-field and multi-type equipment models, and realize data communication between different levels and heterogeneous models. To conduct ground equivalent verification of remote sensing satellites through digital means, it is necessary to realize collaborative simulation of engineering-level remote sensing satellite models and satellite system models, other equipment models, and target models.

The real satellite data is introduced into the mission scene, which is conducive to building a mission scene that is closer to the real one, greatly improving the authenticity and credibility of the simulation. At the same time, the obtained simulation results can more accurately reflect the performance of the satellite in actual operation, provide a reliable basis for the research and development, improvement and mission planning of the satellite, and significantly improve the success rate and benefits of the satellite project.

By agreeing on the detection data product format, the data display is not restricted by the real satellite data format. Users can flexibly customize the display method and format of the detection data according to specific analysis needs and application scenarios, making the data more intuitive, easy to understand and analyze.
