ABSTRACT:
A triaxial gyro system includes a loop controller for generating a multiplexed digital biasing waveform. The controller receives the multiplexed outputs of the three gyros in digital form from an analog-to-digital converter. The loop controller is arranged to generate a digital waveform for multiplexed driving of the phase modulators associated with the three gyros. Within the loop controller, the multiplexed gyro outputs are independently processed in such a way that a biasing waveform is generated which permits sequential driving of the phase modulators without any need for resetting buffer cycles.
