| Abstract: | The attitude determination of moving vehicles using GPS carrier phase is studied in this paper.A determination system with two GPS receivers for two-dimension application is suggested.The design and imple-mentation of the system is proposed.The hardware topology and algorithm flowchart are given.Key techniques are investigated,including observation equation,model of Kalman filter,the integer ambiguity solving and the error e-limination.The feasibility of the system is therefore verified. |
