在弹箭设计过程中，为了获得弹体飞行时的气动参数，通常采用地磁传感器来测量弹体的姿态信息，而采用的三轴磁传感器都存在误差，因此，对误差的校正就显得很有必要了。在文中提出了一种新的校正方法，该方法是对已有的常规误差校正方法的扩展，使之能用来对磁传感器的时变误差进行校正。这种方法可用于复杂电磁环境中的弹载测量系统，可以有效校正磁传感器的测量误差，最后通过仿真实验数据对结果进行了验证。

In missiles design process, in order to obtain the dynamic parameters of the missile in flight. We usually use the geomagnetic sensor to measure the attitude information of the projectile. However, there are some errors of three-axis magnetometers which we commonly used. Therefore, the calibration of magnetometers measuring error is seems very important. This article put forward a new method which to calibration the time-varying error of three-axis magnetometers. This method is an expansion for the existing method which is constant error. So that the magnetometer can be used for calibration with time-varying bias. This method is particularly suitable for complex electromagnet-ic environment onboard measurement system that can effectively calibration the measure error of three axis magnetometer. Finally, the re-sults were verified by simulation data.
