实践十号返回式卫星自主安全控制策略设计

Design of Autonomous Safety Control Strategy for SJ-10 Reentry Satellite[JZ)][HS)]

摘要:

自主运行和健康管理是航天技术发展的一个重要趋势；为确保实践十号返回式卫星在飞行中的设备安全、整星能源安全和自主运行需求,从卫星系统层面进行了自主安全控制设计;首先,可以使卫星在测控弧段之外出现地面无法反应的故障时能够启动自主安全保护模式；其次,可以使卫星自主执行程序化的功能,减轻地面人员的遥控数据上注压力;实践十号卫星在轨飞行中所采取的系统级自主安全控制策略以及工程设计经验,是对航天自主运行和健康管理技术的有益探索和尝试,对后续航天器的设计有很大的借鉴意义。

Abstract:

With the space technology advancing, the spacecraft autonomous flight and self-management is important. To satisfy the demand for equipment safety, energy safety and autonomy, systemic strategies are designed for the SJ-10 reentry satellite. Firstly, survival capability can be improved to against major fault beyond instant ground responses. Secondly, data transfer overhead between aerospace and ground station can be lowered with the self-management. This paper discusses the systemic design of autonomous safety control and self-management of SJ-10 satellite. The engineering practices are useful for the development of space autonomy and maintenance.
