RDSS定位、定时中电离层时延仿真

Simulation of Ionospheric Delay in RDSS Positioning and Timing

为了探讨电离层对RDSS定位、定时精度的影响，本文基于RDSS测距原理，利用国际电离层模型进行了区域仿真，并试用距离差分改正法进行了定位仿真。结果表明，使用距离差分改正法可有效削弱电离层传播误差，提高导航系统服务性能。

In order to analyze the influence of ionospheric delay on RDSS poisoning and timing accuracy, the regional ionospheric delay is simulated by using the international ionospheric model, and the positioning simulation is carried out by using the distance differential correction, which is based on RDSS distance measurement principle. The result shows that the distance differential correction is an efficient method for reducing the ionospheric delay error and improving the navigation system service capability.
