  5. Major applications • Gyroscopes are primarily used to: • Sense or measure the pitch, roll, and yaw attitude angles for: 1 • Spacecraft or aircraft stability • Inertial guidance systems for ballistic missiles • Black box navigational systems • MEMS [2] [3]

  6. What is it? • GYROSCOPE: • A device for measuring or maintaining orientation based on the principles of conservation of angular momentum 1 • A self-stabilizing device, consisting of a rotating heavy metal wheel pivoted inside a circular frame whose movement does not affect the wheel's orientation in space. 4 [5]

  7. Configuration • Function: • Spinning wheel or disk whose axles free to take any orientation. This orientation changes much less in response to a given external torque than it would without the large angular momentum associated with the gyroscope's high rate of spin. • Since external torque is minimized by mounting the device in gimbals its orientation remains nearly fixed, regardless of any motion of the platform on which it is mounted. [1]

  8. Specification • Great variance in specification needs for any given application • Rate grade gyroscopes • Automotive application • Developed mostly in recent years. • Optical gyroscopes • Most accurate • Ring laser gyroscopes • Demonstrate inertial grade performance • Fiber-optic gyroscopes • Tactical grade application [6] Specifications of gyroscopes in 3 different applications

  10. Conclusion • Gyroscopes, over the past century, have come to be a very vital part of aerial transportation, and will continue to do so. • Gyroscopes promote precise tuning of the resonance frequencies of the drive and sense modes of the resonators. This is required to get sense signals large enough to be reliably determined from the mechanical sense modes at rather small resistances. 6
