利用高速回转体的动量矩敏感壳体相对惯性空间绕正交于自转轴的一个或二个轴的角运动检测装置。利用其他原理制成的角运动检测装置起同样功能的也称陀螺仪。-The use of high-speed rotary member relative to the housing of Momentum sensitive inertial space orthogonal to the axis of rotation around one or two axes of angular motion detection means. Principle made use of other angular movement detecting device is also known from the same function as gyroscopes.
