Module 2. Physics

A gyro with a fixed point free to rotate in three axis is

  • a tied gyro.
  • a free gyro.
  • a rate gyro.

Explanation

A gyro mounted in two gimbals so that its spinning rotor is free to move about all three axes, while its centre stays fixed, is a free (space) gyro. With no external constraint it maintains rigidity in space. A tied gyro is constrained to a reference, and a rate gyro is restrained on one axis to measure turn rate.
