Low-Cost Miniature and Accurate IMU with Vibrating Sensors for Tactical Applications

摘要

During the 1996 Symposium on Gyro Technology in Stuttgart we presented a paper entitled "The Quapason, a new low-cost vibrating gyroscope" [1] 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 is now in full production and used in many applications. We also discuss two other vibrating inerttal 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 accelerometer (VBA) These sensors will be used together in a miniature inertial measurement unit (IMU) for various medium performance applications.
