Abstract

The paper describes a modified smooth approximation method for smoothing the dependence of the equivalent fluence of charged particles of the Earth’s Van Allen radiation belts on time and position in near-Earth space. It is shown that this method can be effectively used to solve the problems of minimizing radiation-induced degradation of spacecraft solar cell arrays. The latter problems involve the variation of the trajectory that the spacecraft follows during an electric propulsion transfer from an initial orbit to a geostationary one.

低推力静止轨道插入过程中太阳能电池辐射退化最小化问题的等效通量函数平滑

摘要

本文介绍了一种改进的平滑近似方法，用于平滑地球范艾伦辐射带的带电粒子等效能量密度对近地空间中的时间和位置的依赖性。结果表明，该方法可以有效地解决使航天器太阳能电池阵列的辐射引起的退化最小化的问题。后一个问题涉及航天器在从初始轨道到对地静止轨道的电推进过程中遵循的轨迹变化。
