Spinning mass gyroscopes use a steadily-moving mass with a free-moving axis (gimbal). They are very fragile and require regular maintenance. When a spinning mass gyro is tilted, the gyroscopic effect causes precession – motion orthogonal to the direction tilt sense – along the axis of the rotating...

In addition, the middle finger points. in the direction of the precession vector. This is also known as the law of gyroscopic precession. Types of Spinning Mass Gyros. There are two basic types of single axis, spinning mass gyros. A rate gyro which is an open loop system and a rate. integrating gyro...
