摘　　要：提出了当前型号和预研中有关航天器制导、导航和控制技术六个方面有待解决的问题：２０００．０星上计算机实时计算轨道的时间系统和坐标系统标准化；星载高精度、高可靠ＧＰＳ实时定轨、定姿组合系统；制导、导航和控制系统的小型化；２１世纪的交会对接技术；第四代航天员舱外活动控制技术；微小智能月球车／火星车控制技术。仅提出了一些非常粗浅的想法，作为抛砖引玉，以期引起决策管理部门的重视。The paper summarizes six problems present in ongoing and predevelopment projects to be solved, i.e. standardized 2000 0 timing system and coodination system for on board real time orbit determination, on board real time GPS combined attitude and orbit determination system with high accuarcy and realiability, miniaturized spacecraft GNC system, 21th century oriented RVD technology, fourth generation astronaut extra vechicular activity ( EVA ) technology, miniaturzied intelligent lunar rover/Mars rover control technology. As “to cast a brick to attract jade”, some superficial ideas are presented only in order to attract the attention of the management and policy making departments to them.
