与载人航天一期“轨道舱”相比,载人航天二期天宫一号目标飞行器对控制计算机的功能、性能和环境适应性都提出了更高的要求.依据GNC分系统对控制计算机的功能与可靠度需求,介绍天宫一号目标飞行器控制计算机的容错方案、硬件设计、系统软件设计、可靠性分析和试验验证情况,地面验证结果表明:天宫一号目标飞行器控制计算机设计满足GNC分系统的需求.
Compared with manned space flight “a” “orbital module”, the manned space two Tiangong 1 target aircraft control computer functions, performance and environmental adaptability have put forward higher requirements.According to the GNC subsystem control Tiangong-1 target aircraft control computer fault-tolerant programs, hardware design, system software design, reliability analysis and experimental verification of the situation, the ground validation results show that: Tiangong-1 target aircraft control computer designed to meet the GNC Subsystem needs.
