PURPOSE:To contrast the attitudes of this ship and the opposite ship on a CRT display device by providing various means which receive and store the gyro azimuth of the opposite ship and calculates the turning speed from the stored azimuth. CONSTITUTION:The bow azimuth signal of the opposite ship S2 is detected by its gyro and modulated 2 and 3 into digital signals, which are transmitted 4 and 5. The signals are received 7 by this station S2 and stored in a memory 10 by a CPU 9 at intervals of unit time. The azimuth data of this ship S2, on the other hand, is stored in a memory 11 by the CPU 9 at intervals of unit time by passing a signal from its gyro 18 through a circuit 8. Consequently, the CPU 9 calculates the turning speeds of the opposite ship S2 and this ship S1 and the digital azimuth of this ship S1 from specific expressions, and the CRT display device 14 displays the rotating speed table DS and turning directions DSL and DSR at the upper part distinctively between this ship S1 and the opposite ship S2, an azimuth scale B at the intermediate part, and the gyro azimuth G at the lower part. |
