- W4320514788 abstract "卫星在轨运行时，本体会产生一定的磁干扰，一般通过伸杆将传感器远离卫星本体安装，或者通过多个磁场传感器测量磁场梯度的方法来消除卫星本体的磁干扰.使用磁场梯度张量仪测量磁场梯度时，张量仪本身的构型会给测量带来误差.通过对5种主要的张量仪构型进行误差仿真，对比5种构型的张量测量误差，发现十字形构型张量仪的测量误差最小.除了构型带来的误差，张量仪的主要测量误差还包括组成张量仪的三轴磁强计本身的误差和非对准误差.本文使用椭球拟合算法对磁强计本身的误差进行校正，校正后磁强计测量总场的均方根误差为0.864nT.针对张量仪的非对准误差，提出了正交系间非对准误差的校正方法.仿真结果表明，校正后的非对准角度误差≤3.2×10<sup>-5</sup> rad，能够很好地降低张量仪的非对准误差." @default.
