Preliminary discussion of multipath effect model on sea surface

LIU Yong-yi①②,DANG Ya-min①②,XUE Shu-qiang①(①Institute of Geodesy and Geodynamics,Chinese Academy of Surveying and Mapping,Beijing 100830,China;②Geomatics College,Shandong University of Science and Technology,Shandong Qingdao 266510,China)  
In the ocean of surveying and mapping,GNSS positioning accuracy is influenced by multipath effect inevitably.Following the general principles of multipath effect model,sea surface environment based multipath effect model was preliminarily discussed in this paper.The process of static environment on lake surface and dynamic environment on sea surface were simulated.Based on each parameter's geometric relationship,the position of multipath effect and the distance of signal delay were deduced.Then the multipath effect locations were calculated through the simulation data to verify the effectiveness of the formulas.
