ABSTRACT:
Disclosed is an apparatus for obtaining an output signal from a dithered ring laser angular rate sensor devoid of dither spill over into the output signal. For a single sensor, the output signal is sampled at two points separated in time by one half of the dither period. Also disclosed is an inertial sensor system in which each of the sensors are sampled about a common strobe pulse and separated in time corresponding to one half of their respective dither periods.
