Comparative analysis of studying on GPS station non-linear variation
Cui Jianyong · Engineering of Surveying and Mapping · 2011
Taking GPS residuals as research object,we use three methods(Box-Jenkins method,Pandit-Wu method,triangle method) to deal with the GPS residuals,and take them for comparing.It is found that Pandit-Wu method is the best one,and triangle method is worse than the others.However,through different experiments,it is also found that triangle method can exhibit the law of non-linear variation directly,which can help us go deep into studying on the reason of non-linear variation.So it is worth for further study too.
