摘要
系统误差是影响地磁测量模块工程化应用的关键问题,为了提高解算滚转角的精度,需要对系统误差进行补偿。论文中对零偏误差、灵敏度误差、正交误差等主要系统误差的产生机理进行了分析,提出了相应的补偿方法和软件补偿方案。在转台环境下,通过实验验证了该补偿方法的有效性。
System error is the key problem which affects engineering application of Geomagnetic measurement module. In order to improve roll settlement accuracy, it is necessary to compensate the system error. Generation mechanism of the main systematic errors, such as zero-bias error, sensitivity error and orthogonal error are analyzed; and corresponding compensation methods and software compensation schemes are proposed. Validity/effectiveness of the compensation method is verified by using a turntable.
