A New Method for Vessel Attitude Determination Using GPS

A new method for vessel attitude determination is presented.The attitude determination not only uses the difference between receivers but also uses the transformation relation between local level system(LLS) and body frame system(BFS),thus this method need not calculate ambiguity and possesses high efficiency.Based on the analysis of the result,the validity of the method is proved and the precision of attitude is better than 0.5 degree.
