无线电干涉测量在深空航天器导航中的应用

介绍了用于确定航天器相对于自然射电源或另一颗航天器角位置的几种无线电干涉测量技术及其在深空探测航天器导航中的应用。差分干涉测量通过对传播时延进行差分消除了大量公共误差,可以达到很高的测角精度,对深空航天器的导航具有重要意义。针对几种干涉测量技术中包含的相位整周模糊这一关键问题,介绍了当前国际上的几种解决方法。系统地分析了影响干涉测量的主要误差源,并对这一领域未来的发展趋势进行了展望。

An Introduction to Application of Radio Interferometry in Deep Space Navigation

This paper describes a variety of interferometric techniques that could be used for measuring the angular location of a spacecraft with respect to natural celestial radio sources or another spacecraft,as well as their applications in deep space navigation.The differential propagation time-delay techniques largely cancel the common error sources and normally achieve low angular coordinate errors.Various methods to solve cycle ambiguity,a key issue to all these techniques,are discussed.The main error sources ...
