| 摘 要： | 采用自编数据处理算法对部分iGMAS与MGEX站点的观测数据进行分析,结果表明,北斗新信号表现优异,数据完整率和信噪比弱于GPS,多路径误差和伪距噪声与GPS相当,电离层延迟变化率优于GPS。总体而言,北斗三号与GPS处于同一水准。

| Abstract: | Abstract: In this paper, we analyze observation data collected from iGMAS and MGEX reference stations based on the self-written data processing algorithm. The result indicates the outstanding performance of Beidou new signals. In the aspects of data integrity rate and signal-to-noise ratio, BDS-3 signals are weaker than GPS. In terms of the multipath error and pseudorange noise, BDS-3 signal is at the same level as GPS. Regarding ionosphere delay rate, BDS-3 signals are better than GPS. On the whole, the performance of Beidou-3 is equivalent to that of GPS. |
