Gao Xian · Zhongguo gonglu xuebao · 2002
This paper presents a method of self difference GPS positioning by fictitious datum station,which is suited to settled line such as railway and highway.Some problems such as the foundation of dynamic fictitious datum station,the neural network framework of fictitious datum station are discussed.The method of neural network training is described.The experiment has testified the system positioning precision is improved,and the dynamic tracking ability is strong,too.
