資源簡介
自主式CCD星敏感器(或稱為星跟蹤器)自身帶有微處理器,是一種智能化的姿態(tài)敏感器。由于其指向精度高、無姿態(tài)累計誤差以及具有快速故障恢復(fù)能力, 已成為航空、航天以及軍事領(lǐng)域備受關(guān)注的研究對象。利用星敏感器確定衛(wèi)星姿態(tài)就是對出現(xiàn)在星敏感器視場中的恒星進(jìn)行識別,通過星光矢量確定星圖拍攝瞬間星敏感器視軸在慣性坐標(biāo)系中的指向,進(jìn)而確定航天器姿態(tài)。本文以衛(wèi)星姿態(tài)自主確定技術(shù)為研究背景,對基于CCD星敏感器的星圖識別技術(shù)進(jìn)行了研究。
論文對基于星敏感器確定衛(wèi)星姿態(tài)的技術(shù)流程進(jìn)行了敘述,但重點是對星圖識別算法的設(shè)計與實現(xiàn)進(jìn)行了研究。基于星敏感器確定衛(wèi)星姿態(tài)主要存在以下問題:如何構(gòu)建分布合理并且能夠滿足導(dǎo)航需要的導(dǎo)航星表、如何設(shè)計適應(yīng)性強、精度高的星圖識別算法以及采用何種濾波算法解算衛(wèi)星姿態(tài)等。本文就其中部分內(nèi)容進(jìn)行了研究,并進(jìn)行了實驗驗證
