FIELD: gyroscopic instrumentation engineering. SUBSTANCE: invariant keeping of horizon plane and development of navigational parameters are provided with the aid of gyro platform which uses one three-step gyro as gyroscopic sensing element. Absolute angular speed of modeled Darboux trihedron in projections on its axis is developed analytically. Signals which control gyro installed in biaxial gimbal suspension with angular momentum axis perpendicular to accelerometer sensitivity axes, and which are proportional to horizontal components of absolute angular speed of Darboux trihedron coupled to object are obtained through accelerometer signals proportional to projections of seeming acceleration. EFFECT: higher efficiency. 1 dwg
