FIELD: gyroscopic instrumentation. SUBSTANCE: inertial attitude-and-heading reference system has platform in frame suspension with two axes in horizontal plane, with stabilization system by vertical gyroscope, with integral system of platform correction. Integral system of correction includes two accelerometers, forward coordinate converter (incorporating two cosine calculators, two sine calculators, inverter, two adders), two integrators, backward coordinate converter (including two cosine calculators, two sine calculators, inverter, two adders), two-degree-of-freedom gyro, two circuits of indication stabilization of platform by angle pickups of gyro, platform which carries two accelerometers, two-degree-of freedom gyro and gyroscopic pickup of angular velocity. EFFECT: enhanced functional accuracy and reliability of system. 1 dwg
