2、SpacecraftTT&CTechnology,2016,35(2):117—124.低軌衛(wèi)星月影事件預(yù)報(bào)優(yōu)化。朱興鴻,苗園青,袁仕耿(航天東方紅衛(wèi)星有限公司·北京·lO0094)摘要:針對(duì)衛(wèi)星月影問(wèn)題,提出了一種低軌衛(wèi)星優(yōu)化的月影預(yù)報(bào)策略,可以有效提高目前低軌衛(wèi)星在軌管理時(shí)對(duì)月影事件預(yù)報(bào)的效率。結(jié)合仿真對(duì)產(chǎn)生月影事件的太陽(yáng)、地球、月球的三體關(guān)系進(jìn)行了分析,首先給出了月影產(chǎn)生的解析分析方法,并通過(guò)對(duì)一個(gè)三維月影影響模型的分析,得到了月影影響區(qū)間的判定要素——月影臨界角;然后進(jìn)一步通過(guò)對(duì)月影臨界角的
3、分析,提出了基于太陽(yáng)與白道面的位置關(guān)系和月影-臨界角對(duì)低軌衛(wèi)星月影事件的優(yōu)化預(yù)報(bào)方法;最后基于大量的隨機(jī)低軌衛(wèi)星場(chǎng)景對(duì)本方法的正確性進(jìn)行了驗(yàn)證。研究結(jié)果表明,此方法能夠較大地提高月影預(yù)報(bào)效率,可以將月影預(yù)報(bào)頻率從每月1次降低到每年2次,從而簡(jiǎn)化了低軌衛(wèi)星在軌運(yùn)行管理的任務(wù)復(fù)雜度,為衛(wèi)星的在軌可靠運(yùn)行提供支持。關(guān)鍵詞:低軌衛(wèi)星;月影;預(yù)報(bào)優(yōu)化;月影臨界角;在軌管理中圖分類號(hào):V556文獻(xiàn)標(biāo)志碼:A文章編號(hào):1674—5620(2016)02一0117—08D()I:10.7642/i.issn.167
