General cell technology applied in micro-spacecraft

Base on the description of general cell (GC), a demonstration system was developed with the volume of on-board electric system in 200 mm × 28 mm × 138 mm and dry mass 640 g. This demonstration system integrated on-board computer, attitude control system, and a communication sub-system in a black box called information processing unit (IPU). In the unit star sensor, sun sensor, magnetic meter, gyro and GPS receiver were connected by CAN bus and the whole system weighted less then 5. 5 kg. In the same time the related spacecraft test bed includes ground station and actuators (reactive wheel and magnetic-torque rod) and can realize autonomous attitude control.
