SYSTEM OF ASTROINERCIAL NAVIGATION Russian patent published in 2017 - IPC G01C21/02 

FIELD: physics.

SUBSTANCE: objective is solved through a system of astroinertial navigation consisting of a teleblock placed in a frame of the biaxial gimbal suspension with the sensors of its angles in azimuth and altitude, the engines of processing the angles of its location in azimuth and altitude and installed within the outer gimbal suspension - the horizon repeater, an onboard digital computer, a block of tracking systems of processing the aiming angles of the teleblock containing the first and the second differential circuits, the first and the second correction blocks, a block of calculating the angular amendments, an on-board digital computer connected by the first and the second output to the first inputs of the first and the second differential circuits, the second input of the first differential circuit is connected to the output of the angle sensor of the teleblock gimbal suspension, the second input of the second differential circuit - to the output of the angle sensor of the teleblock gimbal suspension in azimuth, and the outputs - to the inputs of the first and the second correction blocks, the output of the first correction block is connected to the input of the engine of processing the angles of its location in azimuth, the output of the second correction block - to the input of the engine of processing the angles of its location in altitude, the third one - to the third output of the onboard digital computer, the output thereof is connected to the block of calculating the absolute difference value between the estimated and the actual coordinates of the viewed star, the output of which is connected to the input of the block of comparison, the first output of which is connected to the input of the block for calculating the errors of the corrected system and the formation of the readiness feature of the corrective amendments, and the other output of which is connected to the input of the block of the formation of the unreadiness feature of the corrective amendments.

EFFECT: improving the accuracy and noise immunity.
