随着科学视野的不断扩大,当今基于地基系统的GNSS导航定位技术无法满足深空探测飞行器导航定位的需要。新兴的脉冲星导航技术可为深空探测飞行器进行导航定位。因此,将从当今基于地基系统的GNSS导航定位技术存在的问题,什么是脉冲星,脉冲星导航定位基本原理以及脉冲星导航发展现状四个方面说明脉冲星导航技术发展概况,并提出若干思考。
With the continuous expansion of science, GNSS navigation and positioning technology based on ground-based system can not meet the needs of deep space exploration vehicle navigation and positioning. Emerging pulsar navigation technology for deep space exploration vehicle navigation and positioning. Therefore, this paper will give an overview of the development of pulsar navigation technology from four aspects: the existing problems of GNSS navigation and positioning technology based on ground-based system, what is the basic principle of pulsar and Pulsar navigation and positioning, and the development status of Pulsar navigation.
