Abstract: Trajectory correction is a significant improving aspect of simple homing of traditional ammunition. Measurement of projectile attitude is the key technology in the correction. Applying the geomagnetic field to detect the attitude information is the hot spot recently. This paper gives more attention to the application range of magnetic resistance sensor when they are employed in the projectile. The geomagnetic field anomaly interference and the self-element of magnetic resistance sensor are put forward in the following words， especially in the situation that the trajectory of projectile is parallel with geomagnetic field direction. From the analysis， more theory information is provided to the coming application.
Key words: magnetic resistance sensor； application range； geomagnetic field measurement； reference
