摘要
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。对结果进行分析和比较 ,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 ,也要进行纵向比较 。
With the engineering practice,the auhtor select some methods to deal with height fitting of a GPS control net of Guangdong province.By analyse and compare,the paper come to the conclusion:When select a model for GPS height fitting,you should compare the precise with the same model and different conditions,and with the same condition and different model.
