【摘要】 对GPS获取的大气延迟改正加密内插的三种方法进行了简述与比较。并通过算例分析,得出从GPS观测值中获得的对流层延迟改正的双差分数据,采用距离反比加权内插法(IDW)和克里金内插法(Kriging)插法是比较有效的。更多还原

【Abstract】 In this paper,three interpolation methods of tropospheric delay corrective encryption for GPS data are briefly discussed and compared.According to experimental analysis,the inverse distance weighted interpolation method(IDS) and the Kerry(Kriging) interpolation method are proved to be more effective to process the double differential data of tropospheric delay acquired from GPS data.更多还原
