Considering the development of CORS and higher requirement of positioning accuracy in inland river navigation,it is urgent to establish a CORS system for each inland river in China.However,traditional precision test couldn’t reflect real precision of inland river navigation CORS system comprehensively.A new method of dynamic test for inland river navigation CORS system is proposed considering actual demand of the users and characteristics of inland river navigation CORS system.Based on the CJCORS system,the feasibility of this test method is verified and the test results are analyzed.The method could provide new ideas for the test of inland river navigation CORS system.
