| 摘 要： | 目前我国大多数低轨道航天器均采用太阳同步轨道,但随着科学应用领域需求的不断增长,许多任务提出采用倾斜轨道对实现某种特定的任务目标具有更多的优势。但太阳翼光照条件恶劣在一定程度上制约了对倾斜轨道的应用。文章以此为背景对倾斜轨道航天器在轨光照特性进行深入分析,并在此基础上分别提出惯性定向和对地定向两种航天器太阳翼对日跟踪的若干种方法,并模拟在轨受照环境对其进行了仿真。结果表明,文章提出的若干种跟踪方案能够很好地改善太阳翼的光照条件,至少与地方时上午10点钟太阳同步轨道相当,甚至可以实现垂直跟踪。提出的思路与方法可为长寿命倾斜轨道航天器的总体设计提供参考。

| Abstract: | Sun-synchronous orbit is widely used in MEO and LEO missions in China. With the increase of scientific demand, more and more predominant traits of inclined-orbit are acknowledged especially to achieve specific purpose. But low sunlight efficiency is main application constraint for long life inclined-orbit satellites.This article provides several methods to resolve sun tracking on basis of analysis of sunlight trait in orbit, which can be used for references for system design of long life inclined-orbit sate... |
