چکیده
In order to solve the problem of modeling and inference for a vast complicated system, a new concept of Hierarchy DDBN was proposed here through the layer analysis method, and worked out the inference algorithm of the Hierarchy DDBN based on the strict probability theory. In order to test the validity of the inference algorithm, a series of simulation were conducted. The result showed that the Hierarchy DDBN could model the complicated system in a proper way, and it ccould simplify the modeling process, speed up the inference. Also the result was totally in accord with the human decision. Keyword: Discrete Dynamic Bayesian network, Inference, Algorithm.

Global positioning system (GPS) measurements provide accurate and continuous 3-dimensional position, velocity and time data anywhere on or above the surface of the earth, anytime, and in all weather conditions. However, the predominant ranging error source for GPS signals is an ionospheric error. The ionosphere is the region of the atmosphere from about 60 km to more than 1500 km above the eart...
