摘要
天文导航定位精度高、设备简单可靠，不受地域、空域和时域的限制，定位定向误差不随时间和航行距离的增加而增大或积累，不受人为因素干扰和破坏，同时还具有隐蔽性好、可靠性高、生命力强等优点，使得它在航海、航空和航天的导航与制导中都得到了广泛的应用。本文论述了天文导航的发展趋势及其关键技术。
Celestial navigation system has the advantages of high positioning precision and simple and reliable equipment. It is independent of local, space and time. The errors of positioning and orientation don＇t accumulate and increase with time and distance. And it is free from being interfered or destroyed artificially. Also, it has the characteristics of well-concealing, high reliability and strong survival. With all of excellence, celestial navigation system has been used in the navigation and guidance of marine, aviation and space field. The paper describes the development trend and key technologies of celestial navigation system.
