Abstract: This paper introduces the method of GPS applied to high speed railway control survey and accuracy analysis.Using the data collected by the GPS receiver, the three difference model method is used to solve the data.With the new method at home and abroad, the precision analysis is carried out at the present stage, and the data are processed by a variety of means, which makes the precision indexes of the control net results meet the requirements.Because of the difference between the accuracy and the process of the calculation, this paper deals with the problems in the high speed iron GPS control measurement and the analysis of the data processing with the example of the Xi'an-Chengdu high speed rail project.The connection between the network structure and the positioning accuracy of GPS is summarized, and then the GPS net with good precision, reliable results and more economical is provided, which provides theoretical guidance for engineering practice.

Key words: data processing, baseline solution, shape layout, Xi'an-Chengdu high-speed railway
