摘要
基于香港卫星定位参考站网(SatRef)15个测站共6d的数据,联合GPS和GLONASS进行对流层三维水汽层析实验。结果表明,相比GPS单系统,GPS/GLONASS组合系统能显著增加信号穿越的网格数量,提高层析水汽分布的精度,平均改善率为36%。
Based on data collected for six days at fifteen stations of Hong Kong satellite positioning reference station network (SatRef) in 2014, we combine GPS and GLONASS to perform a three dimensional water vapor tomography experiment. The results show that the integrated GPS/GLONASS system can significantly increase the number of voxels which are passed through by the signals. The system improves the accuracy of distribution of water vapor by an average improvement rate of 36% in comparison with a GPS-only system.
