RADIO-INERTIAL NAVIGATION SYSTEM INERTIAL PART READINGS CORRECTION METHODS Russian patent published in 2025 - IPC G01C21/20 

FIELD: physics.

SUBSTANCE: present group of inventions relates to radio-inertial navigation systems (RISN). Substance of correction methods of inertial part of radio-inertial navigation system consists in the following. Linear speeds and coordinates are determined from the information received by the radio navigation part (RNP), and before correction, both versions of the parameters of the state of the navigation parameters and orientation are recalculated into the same coordinate system (CS), both versions of the obtained parameters of the state are simultaneously filtered and the filtered values of linear velocities and coordinates are used to change the initial conditions during integration.

EFFECT: higher accuracy of operation in both inertial and integrated modes.
