ABSTRACT:
An azimuth data stabilization system for a shipborne mechanically scanned arch-track system. A unitary package is provided mounted on the roll and pitch stabilized search-track system platform. The package includes a gyro stabilized turntable with the axis of rotation thereof aligned parallel to the axis of rotation of the search-track system. A gyro-torquer loop is provided to inertially stabilize the turntable and a synchro or resolver chain is provided to align the turntable with an azimuth reference. Corrected ships heading signals, derived from the angular position of the turntable, are either coupled directly to appropriate data processing equipment or are combined differentially as compensating signals with the azimuth data signals from the search-track system to provide a true azimuth data output.
