PURPOSE:To measure the bearing accurately and continuously with no time delay of the bearing measured value due to the movement of a navigating body such as a ship. CONSTITUTION:A gyroscope device is provided with a satellite receiving antenna 1 installed on a navigating body, an arithmetic means 3 measuring the position and speed of the navigating body with the satellite radio waves received by the antenna 1 and calculating the bearing with the speed, an angular velocity sensor 20 fixed to the navigating body to use the yaw axis of the navigating body as the input axis, an adder E receiving the output signal of the angular velocity sensor 20 and feeding its output to an integrating means 23, a comparing means C comparing the output signal of the integrating means 23 with the bearing obtained by receiving the satellite radio waves, a compensating means 27 for compensating the deviation of the comparing means C, and a means feeding back the output signal of the compensating means 27 to the negative input end of the adder E. |
