    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.
    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
