　　报告题目：Spacecraft Navigation Using X-Ray Pulsars

　　报告摘要：X-ray pulsar-based navigation and timing (XNAV) is a theoretical navigation technique whereby the periodic X-ray signals emitted from pulsars are used to determinep location of a spacecraft in deep space.On this talk,I will introduce the basic Principle of GPS and some basic feature of pulsars.We can find the similarity between GPS and XNAV.At last I will present some pulsar navigation approach that provides corrections to estimated spacecraft position.
