Inertial instrument with a temporally digitized rebalance network

摘要

An inertial instrument has a temporally digitized rebalance network and at least one associated inertial sensor, position signal generator, and torquer. The rebalance network features a digital torque correction network, a digital pulse width modulation circuitry for generating a pulse width modulated rebalance torquer signal, the pulse width being one of a plurality of discrete values, and circuitry for applying those signals to the torquer. A digital output, representing the rebalance signal, can also be made available for further processing.
