This paper presents our latest research in the field of microsatellite sensor network design. In the experiment we've designed the overall structure of system including module layout and circuit design, node application software platform by utilizing system-on-chip CC2530 chip as the hardware development platform. The system uses network communication protocol-stack to set up the system. The system test has yielded good results, showing high receiver sensitivity, ideal communication distance, low latency network communication, high data transmission efficiency and strong network robustness.
