At this time, we developed the new equipment, that was "Course Recorder", which was able to receive Loran-C signals on the X-Y Plotter. Then in December, 1968, we made the experiments on Osaka Bay and the Coast of Tomoga-shima installing this equipment on "TENYO" of Hydrographical Department of Maritime Safety Agency. The conditions of receiving are almost good, so in future we think that we get the good results in utilizing Loran Navigation.
