Abstract

An integrated GPS/INS system provides more accurate estimates of position and attitude compared to individual systems. Availability of inertial sensors and GPS cores has opened up new opportunities for low cost INS/GPS systems which find wide spread application. Different integration techniques of GPS/INS integration have been implemented to obtain accurate position in navigation systems. A loosely coupled GPS/INS integration has been adopted in this paper. Real-time system discussed here is more suitable for navigation systems. In this paper, the modeling on GPS/INS integrated navigation system is design and simulated.
