Angular motion sensor signals (S1, S2) from an inertial integrating rate sensor (10) are provided to a translation device that provides a translated output signal (U1, U2) that is substantial ly the same as an input sensor signal (S1, S2) translated in frequency by an amount equal to a reference frequency (R1, R2) . The translated output signal (U1, U2) is provided to a phase detector (34, 36) that provides a detector output signal (e1, e2) indicative of phase differences between the translated output signal and a feedback signal. The phase detector outpu t signal is provided to a voltage controlled oscillator (42) which provides an oscillator output signal that is related t o the phase detector ouptut signal. The voltage controlled oscillator signal is provided to a counter (44) that is capable o f providing a count that is representative of a highly resolved measure of angular rotation. In addition, the counter (44) i s capable of providing the feedback signal that is related to the variable frequency output signal.
