GYROSCOPIC NAVIGATION SYSTEM

navigation. SUBSTANCE: system can be used for development of precision mobile gyroscopic navigation systems capable of generation of entire nomenclature of navigation parameters. Given system includes two gyroscope-stabilized platforms, first one being placed into outer double-axes gimbal suspension, second one being located in three-axes gimbal suspension. Both gimbal suspensions have external vertical axes and are mounted on rigid base. First gyroscope-stabilized platform carries two-degree-of-freedom gyro with vector of kinetic moment parallel to plane of platform and one accelerometer. Second gyroscope-stabilized platform carries two-degree-of-freedom gyro with vector of kinetic moment orthogonal to plane of platform and two accelerometers. Each gyro includes two torque generators and two angle-data transmitters. Stabilization motor is installed on pivot of first platform. Stabilization motors and angel-data transmitters are mounted on external vertical axis of double-axes gimbal suspension and along all axes of three-axes gimbal suspension. Proposed system incorporates unit for control and generation of navigation parameters. Outputs of angle-data transmitters of gyros, accelerometers and angle-data transmitters mounted along axes of suspensions are connected to inputs of this unit and its outputs are connected to inputs of torque generators of gyros and stabilization motors. System practically generates no errors caused by mutual influence of gyros, constant horizontal drifts of gyros and by " rhomb " errors. EFFECT: enhanced operational precision. 2 dwg
