| 摘 要： | 基于同步的相对导航与精确定位技术是Link16数据链运行的关键。针对国内文献对该技术介绍较少的情况，分析了相对导航的基本原理，研究了利用往返计时报文实现精确同步的方法和步骤，建立了相对导航解算方程以及相对栅格与地理栅格坐标之间的数据转换模型，最后提出了一种用GPS/IMU数据融合和卡尔曼滤波方法提高导航精度的方案。应用结果表明，该方案能显著提高数据链的导航精度。

| Abstract: | The relative navigation and precise positioning technology based on synchronization is the key of Link16 operation. Because there is few detailed explanation about this technology, this paper illustrates the basic principle of relative navigation, studies the method and process of precise synchronization based on Round-Trip Timing message, builds the data conversion mode between relative grid coordination and geographical grid coordination, and finally proposes a scheme to improve the navigation precision with GPS/IMU data fusion and Kalman filtering. The application result shows that the scheme can improve greatly navigation precision of data link. |
