Abstract:	GPS/INS integrated navigation system applying Extended Kalman Filter, which involve integrated principles, scheme and technology combining with real INS and GPS receiver data. This research is mainly concerned with the system error models and integrated system realization. Both loose and tightly coupled GPS/INS integrated system are also analyzed. On the basis of our experience accumulated in the research of GPWNS for many years, we have made the GPWINS integrated navigation developing system. It can be made into efficient and economic use in the study and design of integrated navigation system. It has already played an important role in the aeronautic and astronautic fields in China. This system is not only a computer aided design simulation but also a semi- physical simulation by obtaining real INS and GPS receiver data. So the key software unit of the developing system would be conveniently transferred to engineering applied software in actual hardware integrated system. The application of this system shows that the design ideas and integrated scheme in the development of this system are successful, and can achieve good navigation result.
