一种以自主方式提高GPS定位精度的方法

A New Method of Improving GPS Positioning Precision with Data Processing

本文介绍了一种提高 Ｇ Ｐ Ｓ（ 全球定位系统） 定位精度的新方法．该方法基于本文提出的对 Ａ Ｒ Ｍ Ａ 模型的修正所得到的在线实时建模与预测算法．通过准确地对 Ｇ Ｐ Ｓ 定位数据进行在线实时的建模和预测和在此基础上的自适应滤波；能够提高 Ｇ Ｐ Ｓ定位精度３ 至５ 倍．定点在线数据处理证明了此方法的有效性．

In this paper,we introduce a new method of improving GPS (Global Positioning System) positioning precision.This method is based on a modified ARMA on line and real time model building and prediction algorithm.By the algorithm and an adaptive filtering algorithm based on the modeling and prediction,GPS positioning precision will be improved 3 to 5 times.The tests on a fixed point have proved that the method is correct.This method is of practical value for vessel optimum control and especially for military users.
