In order to reduce the influence of roll angle interval error on the accuracy of the difference-quotient method, a single-axis gyroscope sensitive projectile roll angle rate is introduced based on the three orthogonal magnetic sensors, and a more accurate roll angle interval is obtained by integrating the roll angle rate. At the same time, the single-axis gyroscope can measure the roll angle when the missile enters the magnetic measurement blind area, which widens the application scope of the measurement system. The simulation analysis shows that under the condition of noise interference, the roll angle is measured by using the geomagnetic/gyro combination scheme, and the measurement error is in the range of −1 to 1.5 degrees. |
