根据牛顿力学原理,高速旋转的刚体具有在惯性空间保持其转动轴指向不变的特性,称为定轴性。当该刚体受到垂直于转动轴方向的外力短时,将绕垂直于转动轴和外力矩向量的第三轴转动,称为进动性。常规的陀螺仪具有一个高速旋转的机械转子。利用上述急转刚体的特性,陀螺仪可用来测量运载体(飞机、运载火箭和船舶等)的角位置或角 According to Newton’s mechanics, a rigid body rotating at a high speed has the property of keeping its rotating axis pointing invariant in inertial space and is called as a fixed axis. When the rigid body is subjected to an external force perpendicular to the direction of the axis of rotation, the rigid body is rotated around a third axis perpendicular to the axis of rotation and the external moment vector, which is called precession. Conventional gyroscopes have a high-speed rotating mechanical rotor. Utilizing the characteristics of the above-mentioned sudden rigid body, the gyroscope can be used to measure the angular position or angle of the carrier (aircraft, launch vehicle, ship, etc.)
