Abstract: Through deep research on the “3D navigation application” IALA recommendation and the analysis of international and domestic recent advances in high-tech information technology in the field of navigation applications,according to the routine operational needs of the navigation-aid custody,this paper develops an exploration into management and monitoring of navigation-aid based on 3D simulation technology.Simultaneously,by the use of high-fidelity 3D visual simulation and ship handling simulator,the concrete simulation inspections applied research on the navigation-aid layout was underway.This paper briefly introduces the research of the application of 3D simulation technology in management of navigation-aid.And associated with the status of main channel of Xiamen,from two application layers，one is inspection of navigation-aid interval,the other is verification of the most suitable position for navigation-aid in turning point of channel,this paper presents the way of navigation-aid layout by help from full mission ship handling simulator.

Key words: 3D simulation technology, navigation-aid, scene simulation, distance design simulation
