The test of attitude parameters is important index in the process of moving object test. Aiming at large error of measurement of attitude angle

angular speed gyro in high-speed movement

propose attitude measurement combination based on coil magnetic and acceleration sensors. The outputs value of coil type magnetic sensor contain information synthesis of rotational speed and angular velocity

then calculate angular velocity information of carrier data fusion and attitude solution by extended whole attitude quaternion algorithm. The experiment of semiphysical simulation on three-axis turntable shows that the algorithm is correct. Strength of local magnetic field is not needed

during calculation process

and the method is simple and feasible.
