The technique of precise position fixed for navigation aids has certainly come a long way. And, it seems that the differential GPS (DGPS) is one of the most eminent methods for eliminating or remarkably reducing the error of positioning. On April of this year, the DGPS using maritime radio beacon networks has finally been established all along the coast of Japan by Japnese Maritime Safety Agency. It is expected that the DGPS services will be helpful to the safety of navigation. Under such circumstances, we srt up a new differential GPS by using modem linked with a maritime radio beacon receiver on Yuge Maru, instead of using modem with telephone line. The evaluation tests of positioning accuracy are executed under various conditions, and the excellent results are demonstrated. Then, the positioning system is applied to the measurements of maneuvering modes, which results are also accurate enough. It is proven that the DGPS services provide reliable information, and are of much help, in all phases of ship operations.
