Error compensation in the case of temperature deviations supported in barometric inertial navigation system

摘要

A method for the purpose of error compensation in the case of temperature deviations in barometric supported inertia sensor systems, in the measured values of the acceleration is detected (10) and, if appropriate, be suitably transformed and a corresponding acceleration signal is generated and this for generating a signal representing a geodetic the vertical speed (gvs) integrated once (20) and for generating a signal indicating the height (ifba) a second time (30) is integrated, wherein the obtained signal indicating the height measurement with a barometric altitude value obtained from a standardized standard atmosphere (hstdbaro) is adjusted (82). The error compensation, the generation of a correction variable, which is a function of the deviation of the actual temperature (stt) of the standard temperature in the corresponding height, and the from the measured values of the acceleration signal generated in the vertical direction (vert accel is; gvs; ifba) with which the temperature deviation is representative of the respective correction variable, so that speed - and / or position values (bvs; ifba; ifbapc) are produced, which correspond to a barometric height signal almost.
