摘要
ΔDOR是一种基于甚长基线干涉(VLBI)测量的导航定位技术,在系统硬件性能保持不变的情况下,可以通过增大基线长度来提高定位精度,在深空测控领域有很大的应用优势。介绍了ΔDOR深空导航定位技术的基本原理及国内外发展现状,对ΔDOR系统的关键技术进行了分析和总结,同时,给出了这一技术有待进一步深入研究的探讨。
The △DOR navigation system based on the VLBI theory can improve the measurement resolution by increasing the distance of the baseline and is recommended strongly in the deep space navigation field. The principle of the △DOR for deep space navigation is introduced and the current research status is reviewed in this article. Several key techniques of the △DOR system are analyzed and the development trend of them is proposed. Finally, this paper indicates some problems that need to be studied furthermore in the field.
