Now using a sight gauge vector error correction method and integrated navigation system using the same.

The present invention relates to an integrated navigation system using characters using a line of sight vector gauge correction method and this, using a line of sight vector value, a measure of the line of sight vector known and more specifically to estimating the azimuth angle, using the estimated azimuthal Now using a sight vector that allows characters to and at the same time correction method of such characters gauge to help gauge can be calibrated can be applied to the system, such as ship, air, which requires precise navigation using the integrated navigation system gauge calibration methods and It relates to integrated navigation system using the same. The invention navigation in the chair gauge error correction method in a system, the magnetic sensor itself, the sensor error correction step for correcting an error generated in the azimuth estimating step of estimating an azimuth of the moving body by using a line of sight vector, and the azimuth comprising a magnetic field measuring step and the gauge error correction step party to correct the errors of the gauge chair over an extended Kalman filter using the azimuth estimation data obtained in step, and a magnetic field measuring step for measuring a magnetic field using the azimuth estimated by the estimating step and it characterized in that configured.
