Abstract

Determining the attitude and position in magnetic field of the earth is considered as main method in the future of passive navigation. This paper aims to extract a model for determining the situation in Iran using earth's magnetic field vector. The proposed method uses the reverse of global model of earth's magnetic field. To make the model and its relation with magnetic field vector of the earth, system identification methods have been used. Applied recognition methods include linear method, OE (output Error) and non-linear method, Hammer stein Wiener. All stages for identification and producing the data have been programmed and simulated in MATLAB software environment. Finally, simulation results of this paper indicate the validity of proposed model.
