METHOD OF STRAPDOWN INERTIAL NAVIGATION Russian patent published in 2023 - IPC G01C21/12 G01C19/02 

FIELD: on-board instrumentation.

SUBSTANCE: invention can be used to solve flight and navigation problems in the autonomous control of moving objects (MO). The essence of the proposed method of strapdown inertial navigation is to perform the following steps: technological calibration of newton meters and gyroscopes; autonomous initial alignment to determine the parameters of the initial conditions; generation of primary instrument information based on measurements of triaxial blocks of newton meters and gyroscopes at each point of the current software location; an autonomous orientation operation, in which the components of the geophysical field vectors are determined taking into account information about the movement and rotation of an object in near-Earth space; determination of the specific gravity vector components at the current location of the software; recording the readings of the newton meter unit at discrete points in time; determination of coordinates at each cycle of updating instrument information; autonomous control and normalization by comparing the found parameter values with the reference ones.

EFFECT: implementation of multifunctional operation of a differential inertial navigation system, fully compatible with other navigation systems.
