A position determination system of a hybrid method, which is capable of complementing the problems of a position determination method, in which a global positioning system (GPS) is used, and a position determination method, in which a mobile communication signal is used, by combining the above two methods with each other, is provided. Also, it is possible to improve the reliability and the correctness in determining the position of a mobile communication terminal using a dispersing type hybrid position calculation method and a centralized hybrid position calculation method.
