The Research of Hybrid Navigation System Positioning Model Combined Microwave and Longwave

The hybrid navigation system combined Microwave and Longwave is the important trend of development of modern navigation system, but there not exist effective model to position, because of calculatingly complexity of long wave range. The paper designed the model of the hybrid system, according to the theory, and deal with the problems of engineering fact. And it simulated and compared using the designed model and GPS model; it proved the designed model effective. The usage of that model can combine different navigation source, improve and guarantee the reliability and usability of integrated system.
