摘　　要：介绍了测量粗差探测的基本理论,讨论了GNSS基线分量的粗差探测模型。在此基础上根据GNSS基线的特点,提出了按照基线构造投影到某个方向统计量的最大值进行粗差探测的模型,与传统的单分量探测方法作出对比,并将该方法应用于实测GNSS控制网观测值的粗差探测,该探测模型探测出了传统模型未能探测出的一条基线粗差。The paper introduces the basic theory of gross error detection and gives a detailed discussion of the GNSS baseline component detection model,based on this model,and combined with the characteristic of GNSS baseline,we come up with the detection model of finding the maximum statistics and apply it to a GNSS control network.it can detect some new gross error which can't be found by the tradition model.
