为了监测桂林(25.29°N,110.33°E；地磁坐标：15.04°N,181.98°E)L 波段电离层闪烁,利用桂林的电离层闪烁与TEC监测仪2011年9月至2013年7月的观测数据,在相同的电离层闪烁环境下对 GPS和 GLONASS卫星的信号质量进行了对比。结果表明：GPS和 GLONASS卫星的 L2信号的幅度闪烁强度均比 L1信号大；GPS卫星 L2信号的幅度闪烁强度比 GLONASS卫星 L2信号大；GPS和 GLONASS卫星的 L1信号的幅度闪烁特征相同。在电离层闪烁条件下,GPS和GLONASS卫星的 L1信号质量相当,可联合使用 GPS和 GLONASS的观测研究桂林的 L波段电离层闪烁特征。

In order to monitor L-band ionospheric scintillations in Guilin (25.29°N,110.33°E;geomagnetic:15.04°N,181. 98°E),the comparison of GPS and GLONASS signals quality in the same ionospheric scintillations environment was made by using observational data between September 2011 and July 2013,which were recorded by an ionospheric scintillation and TEC monitor installed in Guilin.The results show that amplitude scintillations of L2 signals are stronger than those of L1 signals for both GPS and GLONASS satellites.Amplitude scintillations of GPS L2 signals are severer than those of GLO-NASS L2 signals.Furthermore,the amplitude scintillations features of L1 signals are same for GPS and GLONASS satel-lites.It indicates that the quality of GPS L1 signals is similar to that of GLONASS L1 signals during ionospheric scintilla-tions.Therefore,GPS measurements can be utilized along with GLONASS observations to investigate the features of L-band ionospheric scintillations in Guilin.
