| Abstract: | In view of the demands of attitude in mobile systems, two attitude determination methods based on the multi-antenna global navigation satellite system(GNSS), the direct method and the least square iterative method are researched. The principles of the attitude determination are analyzed and the models are derived. The data from a test on a land vehicle which used four-antenna are processed by the two methods. The attitude from a high accuracy inertial navigation system(INS) on the same platform is used as reference, and the accuracy and reliability of the two attitude determination methods are evaluated and compared. |
