Abstract: The Student Small Satellite (SSS-1) was launched into orbit from Taiyuan Satellite Launch Center (TSLC) on October 14, 2021 with a Long March-2D (LM-2D) rocket. This paper introduces the project background and space missions of the SSS-1 satellite, and gives its payload configuration and platform system design, including structure subsystem, Thermal Control Subsystem (TCS), Attitude Determination and Control Subsystem (ADCS), On-Board Data Handling subsystem (OBDH), Electrical Power Supply Subsystem (EPS), and Telemetry, Tracking and Command subsystem (TT&C). As the SSS-1 satellite has been in orbit for more than 6 months, this paper also describes its operation and test conditions with the on-orbit data, such as the telemetry of platform health, remote sensing images, and photos recording the deployment process of coilable mast. With these on-orbit achievements, the success of the satellite design and development is completely verified.

Key words: micro-satellite, SSS-1, system design, coilable mast, on-orbit test
