中文摘要： 量子定位技术是利用量子纠缠与压缩特性发展起来的一种新兴技术，它可以突破经典无线电导航体制对功率和带宽的限制，达到高精度保密定位目的，因此受到了美国麻省理工学院等重点研究机构的高度重视。鉴于当前卫星导航的发展现状以及建立独立的量子导航系统实现困难，代价高昂，利用量子定位中的量子纠缠测距增强卫星导航将成为切实可行的发展方向。本项目利用量子脉冲具有的频率纠缠压缩特性可以很好地估计色散媒介所引起的延时特点，研究高精度测距的实现机理，建立实用的量子测距理论模型，在此基础上研究其与卫星导航的结合方式，得到卫星导航网络实时动态差分（RTK）技术中引入量子测距的具体增强方法，以充分利用频率纠缠压缩特性进行可靠高精度定位关键技术。研究成果将大大丰富量子定位与卫星导航相结合理论，促进我国量子定位技术的发展，从而为构建具有自主知识产权的高精度、高动态、高可靠性和大作用范围的导航体系提供有力的理论指导和技术支持。

英文摘要： The quantum positioning technology based on the entanglement and pulse squeezing was the newly developed positioning technology. It can overcome the limitation in positioning precision of classical radio navigation under specified power and bandwidth conditions and achieve the aim of secure positioning with higher precision. Heretofore, high precision quantum positioning technology had attracted great attentions from many foreign research institutes, such as Massachusetts Institute of Technology (MIT). In contrast to the difficulties and cost of establishment of the practical quantum positioning system, the satellite navigation system had undergone a long development history and had been widely utilized. Therefore, it is more practical to enhance the satellite navigation system by means of the quantum ranging. Taking advantage of the characteristic of a good delay estimation of the entangled and squeezed quantum pulse in the dispersion medium, the implementation mechanism of high precision quantum ranging is researched and the theoretical model of quantum ranging under the condition of non-ideal transmission channel is given.On the basis of above mentioned,the integration of the newly quantum ranging technologies and the satellite navigation is studied. The specific enhancement method of satellite navigation ne
