Claim:
1. A method for dynamic self-calibration of an accelerometer system, the method comprising: forcing a first proof-mass associated with a first sensor of the accelerometer system in a first direction to a first predetermined position; obtaining a first net force measurement applied to the first proof-mass in the first predetermined position via a first at least one force/detection element of the first sensor; forcing the first proof-mass in a second direction opposite the first direction to a second predetermined position; obtaining a second net force measurement applied to the first proof-mass in the second predetermined position via a second at least one force/detection element of the first sensor; and measuring a magnitude of an external acceleration via a second sensor of the accelerometer system, the second sensor comprising a second proof-mass, a third at least one force/detection element, and a fourth at least one force/detection element; calibrating the first sensor of the accelerometer system based on the first and second net force measurements and based on the magnitude of the external acceleration measured by the second sensor.
