INERTIAL NAVIGATION COMPLEX FOR HIGH-SPEED MANOEUVRING OBJECT Russian patent published in 2018 - IPC G01C23/00 

FIELD: tool engineering.

SUBSTANCE: inertial navigation complex for a high-speed manoeuvring object starting from a mobile carrier at the required time t₀, containing the inertial navigation system of a mobile carrier, a free-of-charge inertial navigation system of a mobile object. The inertial navigation system of the mobile carrier consists of a block of inertial information of the mobile carrier connected to the on-board computer of the mobile carrier and generates navigation information for controlling the movement of the mobile carrier. The inertial navigation system of the mobile object generates navigational information for controlling the movement of the mobile object after its start from the mobile carrier and consists of the on-board computer of the mobile object to which the first inertial information block of the mobile object is rigidly fixed to the mobile object and the second inertial information block, rigidly fixed on the axis, oriented on the object housing and driven into rotation by the engine and equipped with a tachometer for measuring its angular velocity, and the angular position sensor relative to the mobile object. At time t₀, from the on-board computer of the mobile carrier to the on-board computer of mobile object, the values of navigation information are transferred at this point in time, recalculated on an axis of the coordinate system used for navigation and control the mobile object, and after the launch of the mobile object, movement control is exercised on the basis of navigation information, generated by the platformless inertial navigation system of the mobile object. Additionally, two-stage suspension is introduced, in which the rotation axis is set with a rigidly fixed thereto second unit of inertial information; on suspension axes engines are mounted, reorienting the rotation axis and the angle sensors, winding controlling turning motors of the rotation axis, angle sensors outputs and tachometer output are connected to the input of the on-board computer of the mobile object, outputs of the inertial sensors of the first unit of inertial information and the second unit of inertial information are connected to the input of the on-board computer of the mobile object. After the start to the end of the mobile object movement, the navigation information for controlling its movement is removed from the output of the on-board computer of the mobile object.

EFFECT: providing functional and accurate navigation measurements for a high-speed manoeuvring mobile object starting from a mobile carrier.
