ABSTRACT:
A device for compensating for gyro wheel frequency inaccuracies wherein a reference oscillator feeds a square wave signal to a first and second counter. The second counter also has an input of plus or minus the spin axis angular rate. The first counter scales down the reference signal and the second counter generates a signal having a frequency proportionately higher than the first counter. The output of the second counter provides a signal indicative of angular spin rate displaced from the input gyro axis. The outputs from the first and second counters are fed to an up/down counter which combines the two signals to provide for gyro wheel compensation.
In a second embodiment of the invention a computer having spin rate axis signal from two gyros, control two settable counters to obtain compensation of the gyro wheel of a first and second gyro.
