摘要:

伴随着北斗卫星导航系统的发展成熟，采用多个卫星导航系统可以获得更多的观测卫星进行电离层闪烁监测，极大提高监测的性能，因此利用GPS系统与北斗系统结合进行电离层闪烁监测成为趋势。文中介绍了所研制的GPS/BD双模电离层闪烁监测系统，它可以实时地监测分析GPS卫星L1/L2频点与北斗卫星B1/B2频点信号的电离层幅度闪烁指数和电离层相位闪烁指数，并可显示和存储各项观测数据。文中对电离层闪烁监测系统的硬件、系统嵌入式软件和电离层闪烁监测上位机软件的设计进行了介绍，对消趋势滤波器的设计和闪烁指数的计算进行了详细的讨论，并在最后给出了系统运行测试结果。

Abstract:

With the development of the Beidou satellite navigation system, multiple satellite navigation systems can be used to obtain more satellite observations for ionospheric scintillation monitoring, which greatly improves the monitoring performance. Therefore, a combination of GPS and Beidou for ionospheric scintillation monitoring becomes a trend. The GPS/BD dual-mode ionospheric scintillation monitoring system is described in this paper. This system can monitor and analyze the ionospheric amplitude scintillation index and ionospheric phase scintillation index of GPS frequency L1/L2 and Beidou frequency B1/B2 in real time. It can also display and store various observation data. The design of hardware, embedded software and PC software for the ionospheric scintillation monitoring system are introduced. It is discussed in detail that how to design the detrended filter and to calculate the scintillation index. At the end, the system running test results are given.

Key words: dual-mode multi-frequency ionospheric scintillation monitoring amplitude phase detrending
