Based on the General Cell concept, proposed a satellite system which integrated on-board computer, attitude and orbit control system and TT&C system into an integrated electronic system, and had carried out In-orbit test on Test Satellite III. The composition mainly includes the processor unit and RF unit. This scheme adopts embedded systems technology, SoC technology and RFIC technology as the core technology of the processor unit and RF unit which composed the integrated electronic system. The integrated electronic system which use the multi-processor have enhanced computing and management ability to manage the attitude measurement unit through the CAN bus to accomplish attitude calculation, and use the LNA and PA to improve the RF unit communication reliability. These methods greatly enhance the functional density of electronic systems to achieve the formation platform and high functional density communications payload design. Experiments on Test Satellite III verify the integrated electronic system has a powerful computing, processing capacity and reliable inter-satellite communication capacity. The integrated electronic system can act as a universal spacecraft micro-platform for formation flying satellite payload. This work greatly promotes the development of the miniaturization of spacecraft and formation flying communications technology.
