PROBLEM TO BE SOLVED: To provide an improved vibrating-mass gyroscope system.SOLUTION: A sensor system includes a substantially planar vibrating mass including opposite first and second surfaces and electrodes that extend in a periodic pattern across the first and/or second surfaces. The electrodes include sets of drive and sense electrodes, which are capacitively coupled to respective matching sets of drive and sense electrodes associated with a housing and are separated from and facing the respective first and second surfaces. A gyroscope controller generates a drive signal provided to one of the array of drive electrodes and the substantially matching array of drive electrodes to provide in-plane periodic oscillatory motion of the vibrating mass, and generates a force-rebalance signal that is provided to one of the array of sense electrodes and the substantially matching array of sense electrodes to calculate rotation of the vibrating-mass gyroscope system about an input axis.SELECTED DRAWING: Figure 2 |
