INERTIAL NAVIGATION SYSTEM Russian patent published in 2006 - IPC G01C19/00 

FIELD: navigational gyroscopic devices, applicable in high-precision navigation complexes of movable objects, in particular, in naval ones.

SUBSTANCE: the system has a unit of three accelerometers with orthogonal sensitivity axes, the unit is rigidly mounted on the movable object, and a unit for determination of the angular orientation matrix of the movable object. Besides, the system, additionally uses n series-connected three-channel integrators, selector of time operation mode of the three-channel integrators, unit for computation of the derivatives of the angular orientation matrix, unit for generation of travel increments, unit for generation of the object co-ordinates and velocities.

EFFECT: provided required precision in the condition of vibration action on the object.
