多路径误差每天重复出现,是存在于伪距信号中的日重复项。伪距中的多路径误差可通过滤波的方法提取,但在多路径误差信号和噪声信号频率未知或者重叠的情况下,不能将二者完全分开。本研究尝试提出一种新技术解决这个问题,将伪距中卫星与台站的距离、钟差、硬件延迟、电离层延迟、对流层干延迟项消除后,得到包含多路径误差、对流层湿延迟和观测噪声的残差数据,再通过主成分分析的方法提取多路径误差。通过主成分分析法得到重构的第一主成分每天都重复出现,其亦为伪距信号中的日重复项,理论上是多路径误差。然而,日重复项的数值大小是前人研究的4到5倍。这表明伪距信号中还包含了除多路径误差以外的其他日重复项。通过分析17个台站的结果,本研究发现上述的其他日重复项,在使用相同类型接收机主机的台站之间的相关性更高。这反映了该日重复项与接收机主机型号有关,可能是与接收机主机相关的系统误差。
