ESTIMATION OF ERROR OF CONVENTIONAL INERTIAL SENSOR USING ATOMIC INERTIAL SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a method for obtaining inertial measurement.;SOLUTION: This method includes a step of obtaining a plurality of continuous high sample rate reading values during a certain fixed period from a conventional inertial sensor. Discontinuous low sample rate reading values of accumulated motions are also obtained for the period from an atomic inertial sensor. One or a plurality of observable errors are estimated based on comparison between the low sample rate reading values and the plurality of high sample rate reading values to the conventional inertial sensor. Compensated mixed reading values are determined by compensating the one or the plurality of observable errors to the high sample rate reading values based on estimation of the one or the plurality of observable errors.;COPYRIGHT: (C)2013,JPO&INPIT
