An apparatus for determining an instrument boresight azimuth heading. A typical apparatus comprises a gyro having a first input and a first output and a rocking angle generator having a second output, wherein the second output is communicatively coupled to the first input of the gyro, producing a demodulated signal at the first output. A signal multiplier is communicatively coupled to the second output and the demodulated signal for multiplying the second output and the demodulated signal and producing a multiplied signal and a filter communicatively coupled to the multiplied signal for producing a filtered output.
