METHOD OF DETERMINATION OF NAVIGATING PARAMETERS BY GIMBALLESS INERTIAL NAVIGATING SYSTEM Russian patent published in 2009 - IPC G01C21/10 

FIELD: physics, measuring.

SUBSTANCE: invention concerns data processing in gimballess inertial navigating systems (GINS). Yield parallel evaluation of plurality of matrixes of direction cosines between the bound and navigating frames on the same indications of accelerometres and angular velocity sensor AVS. For each calculated matrix of direction cosines, determine the natural navigating parameters having various frequency character of errors. Thus each of the calculated matrixes has the individual law of guidance, and errors of their evaluation also have a various distribution of modes of frequency depending on modes of a motion of the carrier (the strong maneuver, feeble maneuvering and a cruiser motion without maneuvering) on which the GINS is mounted. Navigating parameters for each calculated matrix of direction cosines submit on inlets of the block of the master filter formativing an optimum combination of navigating solutions depending on the frequency range of their errors, and also from parameters of a motion of the carrier.

EFFECT: increase of accuracy of notation of the output GINS navigating parametres.
