A kind of engineering information conversion system was designed to satisfy the performance requirements for the information conversion system of stabilized gyrocompass. The analysis of conversion principle, interface time requirement, exciter phase lag and zero detection circuit shows the conversion system can perform its function. The methods of calculating angle and compounding attitudeangle with coarse angle and fine angle were described in detail with model stabilized gyrocompass as an example. The analysis of system precision shows that the precision of the conversion system successfully satisfies the requirement for the stabilized gyrocompass. This conversion system has been successfully used in several models of stabilized gyrocompasses.
