地磁场强 meaning in English

geomagnetic field intensity

Through the analysis of the dynamic characteristic of geomagnetic intensity in a orbit , the magnetic dipoles produced by magnetorquer are expanded in fourier series . the new method of momentum unloading is educed according to the need of the sum of unloaded momentum , and the magnetic dipoles are figured out under the theory of optimal control
通过对在轨卫星地磁场强度的变化规律分析，将卫星磁力矩器产生的磁矩按富利哀级数展开，根据卫星所需卸载角动量大小，按照最优控制理论求出三轴磁矩取值，得到一种新的利用地磁场给飞轮卸载的方法。
