GPS leveling fitting based on independent arithmetic of fitting points

FAN Li-zhang,SHI Jin-feng,ZHANG Fei(School of Geomatics,Liaoning Technical University,Liaoning Fuxin 123000,China)  
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.
