FIELD: physics.
SUBSTANCE: integrated navigation channel based on a physical integration filter (PIF) is formed in an inertial navigation system (INS) with an additional autonomous channel. Self-integration of characteristic velocities of the autonomous and corrected INS is provided in the PIF. Errors of the INS are continuously corrected.
EFFECT: increased accuracy.
