| 摘要: |
| 在战时环境下，GPS、“北斗”等全球卫星导航定位系统将受到敌方强力的电子干扰，从而导致其无法实现精确定位，为此提出了一种全新的无线电导航系统，即基于临近空间飞行器的区域导航定位系统。首先简要阐述了临近空间飞行器的特点，在此基础上建立了基于临近空间飞行器的区域导航系统的体系结构；其次从技术层面对其关键技术进行了详细分析，并提出了一些解决措施；最后对该区域导航系统提出几点展望，并指明了当前亟待解决的关键技术，对我国未来建立基于临近空间飞行器的区域导航系统具有一定的理论参考价值。 |

| Abstract: |
| In complex battlefield environment, the global satellite navigation system(GNSS),such as GPS and BD,will be jammed by electronic equipment so that it can not position accurately.Aiming at the problem, this paper proposes a novel radio navigation system,namely regional navigation system based on near space vehicle.First, the characteristic of near space vehicle is introduced, and the architecture of regional navigation system based on near space vehicle is established.Then, from the technical level, the key techniques are analyzed in detail，and some solutions are proposed.Finally,some prospects are presented, and the key techniques to be solved are discussed. The analysis above has an important reference value for establishing China's regional navigation system based on near space vehicle in the future. |
