摘要： A vibratory gyro element 100 includes a fixed part 10, a resonator 20 having a cos Nθ (N is a natural number of two or more) mode of vibration, support parts 30, and electrodes 40. The electrodes 40 are arranged in 4N orientations arranged in an outer circumferential direction of the resonator 20. The electrodes 40 include a primary driving electrode PD, a primary pickoff electrode PPO, a secondary pickoff electrode SPO, and a secondary driving electrode SD. The primary pickoff electrode PPO is arranged in the same orientation as that of the primary driving electrode PD, and the secondary driving electrode SD is arranged in the same orientation as that of the secondary pickoff electrode SPO.

摘要： A vibration-type angular velocity sensor (100) includes a first angular velocity sensor unit (101) and a second angular velocity sensor unit (102). In a predetermined period, the second angular velocity sensor unit performs a process of detecting an angular velocity based on secondary vibration of a vibrator (11) by a secondary side control circuit (17) and a process of detecting the angular velocity based on the secondary vibration of the vibrator by the primary side control circuit (16) by interchanging functions. The first angular velocity sensor unit detects the angular velocity in the predetermined period. The bias component of the first angular velocity sensor unit is calculated based on a first detection result detected by the first angular velocity sensor unit in the predetermined period and a second detection result detected by the second angular velocity sensor unit in the predetermined period.

摘要： A direction detector that allows true north detection accuracy to be improved is provided. In a direction detector 1, an attitude changer 100 rotates an angular velocity sensor 26 around a detection axis and controls an attitude of the angular velocity sensor 26 so that the detection axis is directed in a predetermined measuring direction and an opposite direction to the predetermined measuring direction. A control device 30 controls the attitude changer 100 so that the angular velocity sensor 26 rotates in a first rotation direction around the detection axis before the angular velocity sensor 26 starts to detect an angular velocity around the predetermined measuring direction. The control device 30 controls the attitude changer 100 so that the angular velocity sensor 26 rotates in a second rotation direction opposite to the first rotation direction around the detection axis and, thereafter, the angular velocity sensor 26 rotates in the first rotation direction around the detection axis before the angular velocity sensor 26 starts to detect an angular velocity around the opposite direction.
