Abstract

This invention provides a digital twin method and apparatus for a satellite optical system. Receiving telemetry commands is the step executed by the interface layer in the satellite optical system. The virtual control box serves as the core logic layer, and the virtual camera serves as the unit model layer. The interface layer and core logic layer receive telemetry commands and respond to them in conjunction with the unit model layer, thereby obtaining the simulation results of the satellite optical system responding to the telemetry commands. This layered architecture, where the interface layer focuses on data interaction, the core logic layer handles command processing and logical operations, and the unit model layer focuses on imaging simulation, enhances the system's stability and reliability, providing a stable and reliable virtual platform for the testing and verification of satellite optical systems.
