TEMPERATURE CORRECTION METHOD FOR ATTITUDE AND HEADING REFERENCE SYSTEM

摘要

The present invention relates to a method for correcting temperature of an attitude and heading reference system (AHRS) and to a device to which the same method is applied. More specifically, a proper one from correction methods is used for each sensor in order to increase accuracy of operation of the AHRS and resistance of the AGRS to environmental stress. According to the present invention, the device, which can be used in a wide area at -10°C to 70°C and thus has excellent resistance to environmental stress, can be provided; the device has high accuracy because the device has an error range narrowed by correcting temperature change of each sensor. Each of the sensors is independently corrected. Therefore, the overall accuracy of the device can be increased.
