QEMU-Based Simulation of On-Board Gnc System

To address the new situation of a sharp increase in the demand for aerospace equipment and shortened R&D cycles in the era of intelligent manufacturing, we have designed and developed a simulation software for spacecraft guidance, navigation, and control (GNC) systems. This software provides an out-of-the-box user experience through a modern web interface, integrating functions such as simulator control, serial port print output, remote control and telemetry, and simulator configuration. The high-performance backend, developed in C++, offers capabilities for frontend access, configuration storage, and simulator control. A modular design approach reduces the cost of simulating custom devices for different projects, thereby enhancing development efficiency. Decoupling of the simulator from the dynamic models is achieved through the use of configuration files.
