Abstract: This paper introduced the general information of Beidou satellite navigation system and the relevant experiments on the introduction of the Beidou satellite navigation system into the railway, designed the overall architecture of railway freight tracking system based on Beidou navigation satellite system with higher precision. By researching on data structure and the logical relationship between the train accurate reporting system and transportation dispatching management system, the paper designed the complete system solution. The J2EE technology and Apache CXF technology were applied to design all the interfaces of the system. It was implemented that the latitude and longitude coordinates of the goods were obtained according to the number of cars entered by the user and displayed on the railway geographic information platform. This is of great significance for the implementation of real-time high precision tracking of railway freight.
