METHOD FOR DETERMINING PARAMETERS OF MODEL OF MEASUREMENT ERRORS OF ACCELEROMETERS OF DRIVEN INERTIAL NAVIGATION SYSTEM AS PER MEASUREMENTS OF REFERENCE INERTIAL NAVIGATION SYSTEM Russian patent published in 2014 - IPC G01C21/24 

FIELD: instrument making.

SUBSTANCE: during movement there determined are parameters of a model of measurement errors of accelerometers of a driven inertial navigation system (INS) as per measurements of a reference INS based on measurement of apparent accelerations of a carrier object moving in inertial space and a separable object related to it. Those measurements are made by means of accelerometers of the reference inertial navigation system in a basic inertial system of coordinates (BISC) and by means of accelerometers of the driven inertial navigation system in an instrument inertial system of coordinates (IISC).

EFFECT: improving accuracy of calculation of mass centre trajectory of the separable object; improving accuracy of orientation of sensitivity axes of accelerometers of the driven INS of the separable object in BISC and prediction accuracy of trajectory of the separable object due to eliminating measurement errors of accelerometers of the driven INS.
