摘要
针对GPS测量数据处理过程中时常出现阶跃、震荡及异常值现象,提出了利用伪距定位残差选取有效段落的计算方法和原始测量信息时序分析方法来处理数据,有效地克服了以上问题.工程应用表明,效果显著,消除了异常情况.
An algorithm of valid paragraph selection based on pseudo range position residual is presented to solve the problem of jumping, vibration and abnormal value in the GPS data processing. Aboriginality information of each star is dismantled and scheduled in order to reduce the possibility of miscarriage of justice. The above mentioned problems are resolved. Effective results are obtained in the engineering ap- plication, and the abnormity is eliminated.
