GPS网外部尺度基准观测数据的粗差剔除

Elimination of Gross Error of Observation Data on Exterior Measure Datum of GPS Control Network

介绍Chauvenet准则、Grabbs法、t检验准则、Dixon法等剔除定常型观测值粗差的统计方法。并利用这些方法对GPS网外部尺度基准观测值进行数据处理,有一定的借鉴意义。

In this article, the authors introduce how to use Chauvenet Rules, Grabbs Discriminance, `t' Test Rules and Dixon Discriminance to eliminate stationary gross error of observation data, and use these methods to process observation data on exterior measure datum of GPS control network. It can be used for reference in practice.
