According to the urgent need for domestic substitution of survey equipment,the static acquisition data and dynamic RTK acquisition data are studied respectively based on the Beidou-3 navigation system.This article adopts statistical analysis methods,combined with the case analysis based with the project planning stage measurement of Yantian East Port.The results show that the domestic survey equipment based on the Beidou navigation system can not only meet the accuracy requirements of conventional engineering,but also establish a high-grade plane control network.It has a high cost advantage in the water transport engineering survey,which has good reference significance for accelerating the implementation of the Beidou Navigation System to replace the GPS,and provides beneficial suggestions for similar engineering applications.
