Claims

[Scope of utility model registration request]

A gyro device that is mounted on a moving body and includes a gyro that outputs a detection signal according to an angular velocity as the moving body changes direction, and an azimuth calculation section that is connected to the gyro and calculates the direction of the moving body from the detection signal. The gyroscope is characterized in that the gyroscope is constituted by at least two gyroscopes, and the azimuth calculating section is equipped with an error correction means for suppressing an error based on a comparison of the outputs of the at least two gyroscopes. Gyro error correction device.
