ABSTRACT:
An apparatus and method of determining gyro het phase and acceleration at turnaround using the digitized heterodyne signals. A digital design that incorporates the necessary logic and is integrated into a gyro unit. An integer algorithm that processes the turnaround data to produce a phase correction that can be added to the gyroscope count. Separation of high speed data processing from lower rate data to simplify the code and permit evaluation of turnaround correction performance.
