摘要
为了提升动态情形下数据链相对导航网络的导航精度,提出了一种基于导航源空间分布的数据链动态时隙分配算法.算法基于平面维度的几何分布,利用导航源空间分布的精度因子,在一帧中调整网络的导航时隙分配表.仿真结果显示,该动态时隙分配算法可以改善网络整体的相对导航精度,定位精度提高了25%以上.
In order to improve the navigation accuracy of data link relative navigation networks in a dynamic situation, this paper proposes a dynamic time slot allocation algorithm. Based on the geometric distribution of the plane dimension, the algorithm utilizes the accuracy factor of the spatial distribution of the navigation sources to adjust the network’s navigation slot allocation table within one time frame. The simulation results show that this algorithm can improve the relative navigation accuracy of the entire network, and positioning accuracy is improved by more than 25 %.
