摘要/Abstract

摘要： 摘要：卫星/伪卫星组合着舰导引系统的定位精度与伪卫星的几何布局有密切关系.为提高系统的定位精度研究伪卫星在航母上的布局问题，根据伪卫星的特点以及航母的构造选定伪卫星的8个可布设点搭建舰载机着舰过程的仿真模型，构造舰载机及航母的航行轨迹，同时在仿真模型中引入舰船运动模型.利用精度因子分析在舰船上布设伪卫星对定位精度的影响，进而提出了伪卫星在航母上的布局方案.结果表明，提出的方案能够减小精度因子，尤其是垂直精度因子，提高了定位精度.

Abstract: Abstract：The positioning accuracy of satellite/pseudolite integrated navigation system has close relationship with the geometric configuration of the pseudolites. The layout of the pseudolites on the aircraft carrier is studied in order to improve the positioning accuracy of the system. First, eight points are selected that can be distributed on the aircraft carrier according to the characteristics of the pseudolites and aircraft structure. Then, the simulation model of carrier landing process is built and the flight paths of carrier and aircraft are constructed. At the same time, the ship motion model is introduced into the simulation model in order to be close to the real environment. Finally, the configuration scheme of the pseudolites on the aircraft carrier is proposed after the analysis of the influence of the pseudolites on the positioning accuracy by using the dilution of precision. The results show that the proposed scheme can reduce the dilution of precision, especially the vertical dilution of precision, and improve the positioning accuracy.

Key words: Keywords：landing guidance, pseudolite, dilution of precision, configuration scheme
