Transfer Alignment Algorithm Based on Attitude Information

Two kinds of transfer alignment algorithms based on attitude information were proposed, which were attitude angle matching algorithm and attitude matrix matching algorithm. Simulations were done for comparing estimation performance of the two algorithms when velocity maneuvers and wing-rock maneuvers. The simulations results show the later algorithm is superior to the former in accuracy whichever maneuvers. However, the later algorithm would invalid in case of some certain maneuvers, so this paper firstly proposes selection method of measure variables of the later algorithm, and presents three sets of effective choices.
