亚太大学生小卫星SSS-1系统设计与在轨试验

System design and on-orbit test of Student Small Satellite-1 (SSS-1)

亚太大学生小卫星SSS-1于2021年10月14日搭载长征二号丁(LM-2D)运载火箭从太原卫星发射中心(TSLC)发射入轨,本文就该卫星的项目背景、空间任务等进行了介绍,并给出了SSS-1卫星的有效载荷配置和平台系统设计,包括结构、热控(TCS)、姿控(ADCS)、星务(OBDH)、电源(EPS)和测控(TT&C)等6个典型分系统。卫星入轨迄今已超过半年,对该卫星的在轨运行情况和空间试验任务执行情况进行了描述,给出了卫星平台健康状态、盘绕式伸展臂展开、遥感相机成像等在轨相关数据/图像,从而说明和验证了卫星设计和研发的成功性。

The Student Small Satellite(SSS-1) was launched into orbit from Taiyuan Satellite Launch Center(TSLC) on October 14, 2021 with a Long March-2 D(LM-2 D) 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.
