PURPOSE:To suppress influences of tilting of a buoy antenna due to wave etc. by providing a simple circuit and a small gyro and making starting and stopping of the gyro properly. CONSTITUTION:Mercury contact switches 7, 8 or 7-9 that detect horizontality of a face making two axes (x), (y) perpendicular to a horizontal plane or three axes x1-x3 that intersect obliquely at 120 deg. are arranged. Starting and stopping of the gyro 3 mounted on the buoy antenna body 1 are made properly using on/ off signals from the switches 7-9. Thus, inclination of the buoy antenna 2 caused by wave etc. can be kept within allowable limit around a vertical axis (z). Consequently, the influences of tilting of the buoy antenna due to wave etc. can be suppressed. |
