A New Method of Improving GPS Positioning Precision by Data Processing

Shufang Zhang, Ancun Yuan

Abstract:	in this paper. \ve introduce a new method of ireproving GPS (Global Positioning System) positioning precision. This method is based on a modified ARMA on-line and real-time nlodcl boilding and prediction algorithm. The on-litle and real-ti[]~c model boilding and prediction for GPS data can be nmdc more acc(lralc]y by the mclhod. An adaptive fil[critlg algorithm based on the modeling and prediction will improle GPS positioning precision 3 105 times. The tests on a fixed point haie proved that th -method is correct. This method is of practical Ialoe for vessel optimum control in llon-differential area or ill integrated bridge system ( IBS). and especially for national militan users.
