摘　　要：传统的GPS水准拟合主要是应用某一种拟合模型对拟合点群进行拟合,未能考虑到不同拟合点对同一拟合模型具有不同适应度。针对这一问题,本文提出了基于拟合点独立解算的GPS水准拟合方法,并结合实测数据对该方法进行了测试,结果证明该拟合方案相对于传统模型在精度上有成倍的提高。Traditional GPS leveling fitting, using only one module to fit the cloud of match points, did not consider that the different match points had different adaptations to the same fitting module. As to this, the paper discussed a new GPS fitting method based on independent algorithm of the match points, and also verified the method according to the test data. The result proved that this new module compared with traditional ones got exponential improvement on the precision.
