Performance analysis of transfer alignment for velocity & angle matching and angular rate & acceleration matching

속도 및 각정합과 각속도 및 가속도정합에 대한 전달정렬의 특성 분석

Transfer alignement is the process of initializing attitude of slave INS using the data of master INS. This paper presents the performance analysis of transfer alignment at sea using convariance analysis method. Velocity & angle matching and angular rate & acceleration matching are used for analysis, and the performance of two matching methods are compared. We propose a new method for angular rate & acceleration matching. Under the assumption of accurate modeling of ship flexure, the performance of transfer alignment time and accuray is improved very much for the new method.
