With the increasing complexity and diversity of satellite missions, traditional pure software simulations are no longer sufficient to meet the stringent demands of modern space system development. To achieve more accurate, efficient, and realistic validation of satellite dynamics and subsystems, semi-physical integrated simulation has emerged as a vital methodology in aerospace engineering. This solution, built upon the advanced SIVB simulation and verification platform, integrates high-performance hardware with flexible software frameworks to provide a robust, scalable, and efficient environment for satellite design and testing.

Within the laboratory environment, the system incorporates S698-T development boards, real-time payload processing computers, and ATP platforms, enabling a seamless workflow from model construction to functional validation. The software models cover a wide range of critical domains, including satellite dynamics modeling, spacecraft operations, GPS simulation, 3D visual rendering, and digital star maps. This ensures that simulation results are not only computationally accurate but also visually interpretable for performance analysis.

Historically, simulation technology has played a crucial role in reducing the development cycle and cost of satellite programs. In the new era of global competition and increasingly complex missions, semi-physical simulation will become even more essential, requiring higher levels of real-time performance, precision, and adaptability. This demands a generalized, modular, and scalable platform capable of evolving alongside future challenges in satellite development.

One of the key advantages of this system is its modular design and integration efficiency. It encompasses a modeling development environment, semi-physical simulation units, data acquisition components, and data management modules. The system is capable of generating real-time executable code, which can be deployed on real-time simulation computers, enabling live monitoring of operational signals and online parameter adjustments. Through Ethernet and LVDS interfaces, the platform seamlessly interfaces with development boards and other simulators, greatly enhancing experimental flexibility and interactivity. Furthermore, it is compatible with third-party modeling tools such as LabVIEW and Matlab Simulink, allowing users to quickly develop and validate complex satellite system models.

From a functional perspective, the system supports hardware-in-the-loop real-time simulation, enabling deep integration between hardware and software. It supports fault injection and programmable control management to test satellite robustness under extreme conditions, while its real-time operating system ensures high-performance processing. The platform also features extensible external interfaces to accommodate diverse mission requirements for data collection and analysis. Its software structure, divided into configuration, monitoring, and excitation modules, offers comprehensive lifecycle management from modeling and operation to validation and testing.

In terms of application, this solution is highly suitable for satellite research and development institutions. It can be applied to satellite subsystem validation, functional and interface testing, as well as navigation terminal performance assessments. By completing extensive experimental verification before satellite finalization, this system significantly enhances development efficiency, reduces risks, and improves overall reliability, thereby accelerating innovation and supporting rapid iterations in satellite technology.

More than just a simulation platform, this solution acts as an innovation accelerator for satellite development, delivering comprehensive support from conceptual design through final verification.
