FIELD: physics.
SUBSTANCE: accelerometer assembly and angular velocity sensor unit are mounted on platform in biaxial Cardan suspension. Platform is stabilised around Cardan suspension axes using signals generated by angular velocity sensor, and torque meters mounted on Cardan suspension axes. Apparent accelerations of platform are measured using signals generated by accelerometers. Absolute angular velocity of platform is measured using signals formed by angular velocity sensor. Angular position of object body is measured concerning platform using signals generated angle-data transmitter mounted on suspension axes of platform. Received signals are computer processed and navigation parameters of object is calculated in reference coordinate system.
EFFECT: higher accuracy of evaluation of object navigation parameters using hybrid inertial navigation system.
