FREEFORM INERTIAL NAVIGATION SYSTEM OF MOBILE OBJECT Russian patent published in 2019 - IPC G01C23/00 

FIELD: navigation systems.

SUBSTANCE: invention relates to freeform inertial navigation systems of mobile objects. Freeform inertial navigation system of a moving object additionally contains three rotors with identified mass-geometry characteristics rotating around the axes, each of which consists of five force sensors, said force sensors are in contact with the axis of rotation in the mode of sliding bearings, and the opposite ends of the force sensors are in contact with a housing rigidly mounted on the object, each force sensor generates a signal equal to its compression force; rotor is driven by a torque motor and is equipped with sensors of rotation angle, angular velocity and angular acceleration; the outputs of the force sensors and sensors of angle, angular velocity and angular acceleration are connected to the input of the on-board computer, in which the reactions of the supports of the rotation axes of the rotors of the inertial sensors are successively calculated, eighteen inertial information variables using redundancy to control the correctness of the calculations and increase reliability, fifteen variable navigation information and an object motion control function.

EFFECT: improving the accuracy of navigation measurements for high-speed maneuverable object.
