Design and realization of the high accuracy attitude and orbit control real-time simulation platform for spacecraft

To verify the correctness and real-time performance of the high accuracy attitude and orbit control algorithms for spacecraft mission, the attitude and orbit control software is developed based on the embedded real-time VxWorks operation system, and based on the high accuracy attitude and orbit dynamic simulation software, aground real-time simulation platform is established. The software as well as hardware architecture and interface of the simulation platform are introduced. The key problems are solved, including the synchronization and data communication between the onboard computer and the dynamic simulation computer, and the wireless communication between the on-board computer and the ground control center. The simulation result shows that reliability and real time of the platform can meet the requirements, and the platform provides a good support environment for the attitude and orbit control ground test and performance evaluation for spacecrafts.
