| Abstract: | In this paper the SINS/GPS attitude determination system is studied in earnest. Based on the transfer alignment the application of the GPS attitude determination system in the initial alignment of SINS is studied, also the ambiguity search algorithm is studied on the basis of geometry constrain so as to improve the computation efficiency and reliability of the GPS attitude determination system. Test result shows that the system presented in this paper is effective and practicable. |
