摘要

在磁场不均匀地区或者当背景磁场较大时,传统的基于光泵/磁通门的飞行器背景磁场学习与补偿方法会产生较大的误差。为了克服这一问题,通过分析基于光泵/磁通门的模型求解与补偿方法,推导了机动角度与方向余弦之间的关系,研究了一种基于光泵/GPS的模型求解与补偿方法,该方法通过GPS获取方向余弦因而避免了磁干扰所带来的误差。实际的机载试验表明该方法能够有效补偿飞行器的背景磁场。

Abstract

When environmental magnetic field is not uniform or background magnetic field is much bigger, the classical method using optical pump and fluxgate arise error. For this problem, by analyzing the classical method, the relationship between maneuver angles and direction cosines was derived, and a new method using optical pump and GPS was studied. The new method uses GPS to get direction cosines as it is not influenced by magnetic interference. The experimental result shows that the method has good effect on compensation.
