| Abstract: | The state and measurement equations of the integrated system of differential pseudorange GPS/INS are described and deduced in the paper. The integration and simulation of the differential pseudorange GPS/INS are performed by using Kalman filtering. In the paper the detailed simulation data and programme frame chart are presented. The simulation results show that the integrated system can improve the precision of navigation positioning greatly. It is of certain practical significance for precision approach landing and guidance of airplanes and other vehicles. |
