Patent number: 11680799Abstract: A vibratory gyroscope system having a mechanical resonator (proof mass) and drive circuitry for maintaining oscillation in two axes at a small frequency split. Angular rate input is shifted to the frequency split and modulates both the frequency (FM) and the amplitude (AM) of the oscillations. Unlike other gyroscope modulation techniques which derive rate information from only the FM information and are subject to aliasing for rate signals with bandwidth exceeding the modulation frequency, the innovation uses both the FM and AM information. By exploiting their orthogonality, the image frequencies from the modulation cancel, thus removing the bandwidth limitation.Type: GrantFiled: April 3, 2020Date of Patent: June 20, 2023Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Bernhard Boser, Burak Eminoglu
