基于北斗卫星信号的电离层环境测量

Ionospheric Environment Monitoring with Beidou Signals

当卫星信号穿越电离层传播时,电离层会带来时延、闪烁等效应。基于卫星信号的变化可以提取电离层电子总含量、闪烁指数等参数信息。北斗系统的发展为在中国区域的电离层环境测量提供了更为丰富的信号源。文章介绍了基于北斗卫星信号的电离层测量设备的组成,电离层参数的计算方法,并给出了初步的观测结果。

The satellite signal is prone to the delay and scintillation effects when transmitting through the ionosphere.On the other hand,the TEC and scintillation index could be obtained from the changes of signals imposed by these effects.The Beidou system affords more signals for measuring the ionospheric environment especially for Chinese region.An ionospheric monitor with Beidou signals is introduced in the paper.The methods of deriving ionospheric parameters are presented,and the primary results are also given.
