The control unit has a high functional density ratio and are designed with high reliability, long life and antiradiation aerospace devices. By using standardized structure, both thermal design and resistance mechanical environmental design meet the requirements. CAN bus, RSS422 bus, RS485 bus, pulse per second and other interface functions are involved. In addition, time management function, independent execution function, system reconstruction function, autonomous security mode, batch command switch function, on-orbit processing and transmission functions are provided. Our control unit has many nice specialties, such as high reliability, integration, miniaturization and can meet the requirements of the autonomous task execution capability, which can effectively improved the application efficiency of agile satellite and can be applied to high resolution agile remote sensing satellites.
