Abstract :
The integration of inertial navigation system (INS) with Global Positioning System (GPS) receivers has been an area of intensive research in recent years. Using such an integrated system, precise attitude of moving platforms can be obtained. The discussion in this paper focuses on precise attitude determination by GPS/INS integration. A highly accurate attitude determination algorithm of a linear convex combination of a linear-two-point and a quadratic-five-point polynomial to filter and predict GPS/INS attitude data is presented in this paper. An integration experiment of real GPS data and simulated INS data shows the validity of this method
