Abstract
A CVA system includes a sensor system including a pendulous element that rotates about a first axis via first flexures in response to an input acceleration provided along a second axis that is orthogonal with respect to the first axis. A torque-summing gimbal is coupled to the pendulous element via the first flexures and coupled to a housing via second flexures. The system further includes an accelerometer controller that monitors a pickoff signal of the rotation of the pendulous element from a first electrode coupled to the pendulous element and to provide a forcer signal to at least one second electrode coupled to the torque-summing gimbal to force the torque-summing gimbal to rotate about the second axis via the second flexures based on the pickoff signal to provide Coriolis force-rebalance of the pendulous element. The accelerometer controller can determine the input acceleration based on the rotation of the torque-summing gimbal.
