Abstract: How to make the balance among the signal power and solve GPS drifting problem have become the new research focus.It approaches temporal series algorithms that adjustment and checking are conducted in the GPS storage location.The purpose is for guaranteeing the quality of the relevant GPS software and not restricted by data type and source.Key parameters of the algorithm can be manually-controlled and suited to the different data sets and the movement objects.It makes improvement for the positioning accuracy of GPS data and makes certain development of economic and GPS technique.

Key words: problem of drifting, temporal series, autocorrelation coefficient, positioning accuracy
