摘要
随着空间探测任务的纵向深度发展,基于地基设备和操作的现有导航模式无法胜任未来的任务需求,利用遥远宇宙中脉冲星辐射信号信息的脉冲星导航为深空飞行器的精密定轨开辟了新的发展方向.文章介绍了脉冲星成因及辐射机制,在分析现有通用导航模式特点及其在深空任务中的局限性的基础上,阐述X射线脉冲星自主导航原理,对脉冲星导航方法以及X射线探测器等关键技术的发展进行了介绍,最后,对射电脉冲星导航进行了初步探讨.
With the rapid and deep development of space will not be able to meet the increasing precision demand exploration, the existing Earth-based navigation solutions of future spacecraft navigation. Pulsar are rapidly rotating neutron stars that generate pulsed electromagnetic radiation, which provides feasibility of precisely determining spacecraft time and position using X-ray pulsar.A detailed analysis in formation and radiation mechanism of X-ray pulsars is presented.The characteristics of the exiting Earth-based navigation systems, as well as its limitations in deep space exploration, are analyzed, and then the principle of the autonomous celestial-based systems using X-ray pulsar is introduced.This paper gives an overview on the development of pulsar-based navigation and its key technologies including X-ray detector, and gives a preliminary discussion on the radio pulsar navigation.
