Angular Velocity Sensor Correction Method, Angular Velocity Sensor Correction Program, and Angular Velocity Sensor System

An angular velocity sensor system including:

• an angular velocity sensor to measure angular velocities about three axes;
• and
• a controller configured or programmed to correct outputs of the angular velocities about the three axes of the angular velocity sensor;
• wherein
• the controller is configured or programmed to:
• acquire a plurality of types of measurement values of the angular velocities about each of the three axes measured by the angular velocity sensor in a plurality of attitudes from the outputs of the angular velocity sensor;
• and
• calculate correction values for correcting the outputs of the angular velocities about the three axes of the angular velocity sensor based on a latitude in each of the plurality of attitudes calculated using the measurement values of the angular velocities acquired in each of the plurality of attitudes and an attitude angle indicating an inclination of the angular velocity sensor in each of the plurality of attitudes, and an actual latitude value indicating an actual latitude at which the angular velocity sensor is located.
