Abstract
Systems and methods are described herein for determining an inertial parameter. In particular, the systems and methods relate to multiple degrees of freedom inertial sensors implementing time-domain sensing techniques. Within a multiple degrees of freedom inertial sensor system, sense masses may respond to actuation with more than one natural frequency mode, each corresponding to a characteristic motion. Measurement of the inertial parameter can be conducted in the differential natural frequency mode using differential sensing techniques to remove common mode error. The inertial parameter can be acceleration in the vertical dimension. The inertial parameter can be acceleration in the horizontal dimension.
