Micromachined Gyroscope For Angle Measurements
Reduced size, weight and energy consumption Improved reliability and functionality Suitability for low cost, high volume production Sustains energy level and allows on-line compensation of manufacturing defects, thanks to a robust non linear feedback control architecture Allows multi-directional vibrations and does NOT interfere with the inertial Coriolis force, contrary to conventional vibratory type gyroscopes
Avionics systems Navigational equipment (ships, submarines, aircraft, spacecraft) Defense-specific applications
