The article aiming at the carrier＇ s own magnetic field characteristics and the error characteristics of three-axis magnetic sensor establishes geomagnetic navigation interference error compensation model. Though simplify the deformation, it uses least squares estimation algorithm of system identification model to strike algorithm error parameters. Data analysis show ： the method is simple and easy to implement, to simplify the processing of complexity solving, and mainly achieving the error compensation requirements
