Abstract (en)
[origin: FR2789170A1] The invention relates to a vibrating gyroscope comprising a vibrating cylinder (1) that is magnetically or electrostatically excited. Regularly distributed masses (19) designed to lower the vibration frequency of said cylinder are arranged thereon. The inventive gyroscope is much more accurate than conventional gyroscopes and can be produced easily at low cost. The invention can be used to measure angular rotation or angular speed.
