Description

Technical Field

[0001] This invention relates to the field of spacecraft system simulation technology, and in particular to a virtual-real combined remote sensing satellite mission scenario simulation system and method. Background Technology

[0002] Satellite field tests are constrained by environmental conditions, collaborating units, equipment, and funding. Furthermore, the testing process can cause significant equipment damage, leading to complex organization and high costs. In satellite ground testing and verification missions, iterative verification and optimization using real satellites is not feasible. Engineering-grade remote sensing satellite models, relying on professional analysis methods for physical mechanism or constraint modeling, can access real onboard software to perform fine-grained simulations of key subsystems such as integrated electronics, energy, propulsion, attitude and orbit control, onboard data processing, inter-satellite transmission, and data transmission, approximating the real system. Ground-based equivalent verification of onboard software is also possible. Utilizing engineering-grade remote sensing satellite models for mission scenario simulation allows for the analysis and evaluation of various equipment performance aspects, shortening the testing and verification cycle, reducing testing and verification expenses, and optimizing the design and iteration process.

[0003] The application scenarios of remote sensing satellites often involve multiple fields and various types of equipment. To construct realistic mission scenarios, it is necessary to build comprehensive equipment simulation scenarios with all elements, introduce equipment models from multiple fields and of multiple types, and achieve data communication between different levels and heterogeneous models. Digital verification of remote sensing satellite ground equivalence requires the collaborative simulation of engineering-grade remote sensing satellite models with models of various satellite systems, other equipment models, and target models.

[0004] Currently, there is a lack of mission scenario simulation systems that support collaborative simulation of engineering-grade remote sensing satellite models and other simulation models. Summary of the Invention

This enables the integration of onboard software from the actual satellite, introducing real satellite data into the mission scenario. This facilitates the construction of a more realistic mission scenario, greatly improving the realism and credibility of the simulation. At the same time, the simulation results can more accurately reflect the satellite's performance in actual operation, providing a reliable basis for satellite research and development, improvement, and mission planning, and significantly improving the success rate and efficiency of satellite projects.

[0031] By calling the remote control command generation plugin corresponding to the remote sensing satellite model to generate remote control commands and parse telemetry parameters, the interface data format is unified and is not limited by the actual remote control and telemetry protocol format of the satellite. This improves the system's compatibility, enabling it to adapt to different models and specifications of remote sensing satellites, and greatly facilitates users' control and monitoring operations of the satellite model.

[0032] By calling the simulation plugin for remote sensing satellite data products provided by the remote sensing satellite model, and by agreeing on the format of the data products, the data display is not limited by the actual satellite data format. Users can flexibly customize the display method and format of the data according to specific analysis needs and application scenarios, making the data more intuitive, easier to understand and analyze.
