GPS高程拟合模型确定

Decision of Model for GPS Height Fitting

结合工程实际 ,对广东某市GPS网的GPS高程和联测的几何水准采用多种拟合方式进行拟合。对结果分析和比较 ,文章最后得出在选择拟合模型的时候 ,既要对模型进行横向比较 ,即同一模型不同条件之间比较 ,也要进行在纵向比较 。

Combining with the engineering practice, the author select some methods to deal with height fitting of some GPS control network of Guangdong province. By analyzing and comparing, the paper gets the conclusion: When selecting a model for GPS height fitting, you should compare the precision with the same model and different conditions, and with the same condition and different model.
