In this paper, a seabottom matching scheme suital to underwater applications is presented. The principle of the sys tem and the matching algorithm is introduced. The simulation model about the Seabottom Seabottom System is established and sim ulation is executed. The results show that the position errors of the INS can be restrained effectivelly and the navigation accuracy can ben improved by the Seabottom Mapping System.
