摘 要:Getting accurate geomagnetic field value is the prerequisite and foundation for the application of geomagnetic ***,the measuring precision of geomagnetic field is badly influenced by the coupling effect between the field of earth and interference *** magnetic compensation has become the key factor which restrict the progress of geomagnetic *** overcome the problem that environmental magnetic field will influence the error compensation result of geomagnetic field measurement,the geomagnetic field was simulated by *** parameterized geomagnetic measurement compensation model was constructed by analyzing the hard iron and soft iron *** parameters of the model were estimated using least squares based *** results show that this compensation method is easy to be used and which can achieved higher error compensation ability.
