CONSTITUTION:A signal from a gyrocompass 1 is employed as the directional signal of its own vessel, then a signal from a target turning angular speed setting section 4 and positional signals X, Y of the vessel from a position meter 5 are fed to a control operating section 3. Amplifiers 6a, 6b amplify an operated command steering signal delta* which is transmitted to right and left side steering machines 9a, 9b. Amplifiers 7a, 7b amplify the operated command right and left side propeller blade angle signals phis*, phip* and the amplified signals are fed to right and left side blade angle drivers 10a, 10b. An amplifier 8 amplifies an operated command bow thruster blade angle signal phiSM* and the amplified signal is fed to a bow thruster blade angle driver 11.
