为实现观测电子投掷角分布的目标,本文讨论了太阳同步轨道三轴稳定卫星电子观测的多方向设计。分析了磁层电子投掷角分布特征,并根据太阳同步轨道卫星的轨道参数,计算得到卫星运行轨迹上,三个探测器常用安装面正入射粒子的投掷角。在此基础上,进行电子探测器的探测方向设计,结果表明探测器要在任何安装面都满足投掷角观测要求,至少需要在0°、10°、20°、25°、35°、45°、70°、80°和90°共9个方向上设计探测窗口。 |

For the purpose of obtaining electron pitch-angle distribution on sun-synchronous orbit,electron orientation detection requirement for 3-axis stabilized satellites is analyzed in this paper.The characteristic of magnetosphere electron pitch-angle distribution is analyzed.The pitch-angle variation of frontal incidence electron on three usual fixed sides of a 3-axis stabilized satellite is calculated along the orbit.According the pitch-angle distribution characteristic and the result of usual fixed side pitch-angle,it is found that in order to satisfy the detection requirement for pitch-angle distribution,it will be needed to arrange detection windows in 9 directions on the detector: 0°、10°、20°、25°、35°、45°、70°、80° and 90°. |
