    Abstract: In this paper we study the potential application of quantum search algorithm to
    the spacecraft navigation. Traditionally the attitude and orbit determination can
    be achieved by recognizing the relative position/attitude to the background stars
    using sun sensors, earth limb sensors, or star trackers. Due to the massive celestial
    database, however, star pattern recognition is a complicated and power consuming
    job. We propose a new method of attitude and orbit determinations by applying
    the quantum search algorithm to the search of a specific star or star pattern. The
    quantum search algorithm, proposed by Grover in 1996, could search the specific
    data out of an unstructured database containing a number of N data in only O( yiN)
    steps, while it would take conventional computers to look through an average of N /2
    steps. As a result, by taking the advantage of matching a particular star in a vast
    celestial database in very limited steps, we could acquire the position/attitude of the
    spacecraft rapidly for navigation, guidance and control.
    本文主要探討「量子搜尋法」來進行未來太空船的導航的可能性。傳統上,姿
    態跟軌道決定主要利用太陽感測器、地球感測器、或是尋星器來進行背景星空
    比對,再求出其相對位置或姿態。然而,由於星空資料庫太龐大了,要進行星
    座辨視是很複雜且耗能的。本文提出可利用量子搜尋法來字成此一任務。Grover
    於1996年提出的量子搜尋法,能在O( √N可)個步驟內,便能性N筆雜亂無章的資料
    中找出特定資料。對於傳統搜尋法而言,平均需要Nj/2 步才能找到。因此,利用
    量子搜尋法強大的搜尋功能,我們可以在非常少的步驟之內,便從龐大的星空資
    料庫中找出我們需要的星體資訊。並可將之用於計算所需的位置及姿態訊息,導
    引及控制太空船飛行。
