INERTIAL RADIO NAVIGATION SYSTEM Russian patent published in 2015 - IPC G01C23/00 

FIELD: instrument engineering.

SUBSTANCE: system comprises three accelerometers with orthogonal axes of sensitivity, a unit of determination of angular orientation matrix of the object, a unit of calculating the derivatives of the angular orientation matrix, and a unit of generation of velocity increments connected in series with the unit of generation of the object velocities, the unit of generation of incremental displacements and the unit of generation of the object coordinates, rigidly mounted on orthogonal axes of sensitivity of the mobile object from the first to the third gyroscopes, the unit of assessment of gravitational acceleration, the non-autonomous radio navigation system connected by radio line to the unit of airborne radio instrument of the object, the unit of assessment of instrumental errors, from the first to the fifth correction units, the adder, the unit of determining apparent accelerations, the first and the second subtracting units.

EFFECT: improving accuracy of autonomous work of the inertial navigation system when interruption of radio contact with external non-autonomous navigation system.
