Abstract:

At present, the schemes of in-movement alignment mostly base on inertial coordinate, but these schemes need to store inertial vectors information in navigation process, and the position accuracy is not high at the end of alignment process. A new vehicle in-movement fast optimal attitude matrix (FOAM) attitude and position determination algorithm is proposed, which can improve the attitude determination accuracy and reach a higher position accuracy to enter the process of integrated navigation. Finally, vehicle tests prove the effectiveness of vehicle FOAM alignment algorithm.
