Abstract:
In view of that the three-axis components method of the magnetic fields can not give thewhole information about the attitude angle in the navigation and the attitude measurement, theassumptions and the measurement principle of the extremum ratio solver algorithms of the attitudeangle are analyzed based on the two-non-orthogonal magnetic sensors. Combining the actual movementof the projectile and the regional characteristics in China,the measurement error range of the attitudeangle and the blind spots are studied using the error distribution theory and numerical simulation,andthe applicability of the missile body attitude measurement method is discussed. The results indicatethat the error of attitude angles can be kept within ±1°with the[15°,75°]fire angle,and the methodmeets attitude test requirements of the common rotary projectiles. The effectiveness of the measurementprogram is verified by the semi-physical experiments.
