^4fLow-Cost Miniature and Accurate IMU with Vibrating Sensors for Tactical Applications

摘要

^7fDuring the 1996 Symposium on Gyro Technology in Stuttgart we presented a paper entitled "The Quapason, a new low-cost vibrating gyroscope" , Work on this novel gyroscope, composed of four square vibrating beams, has continued and in this paper we present new results concerning its performance. The Quapason~(TM)is now in full production and used in many applications. We also discuss two other vibrating inertial sensors, a hemispherical resonant gyroscope (HRG), into which considerable effort has been devoted in order to produce a low-cost accurate gyroscope, and a vibrating beam accelerbmeter (VBA). These sensors will be used together in a miniature inertial measurement unit (IMU) for various medium performance applications.
