摘要(中) 本論文以建立一套隨載星體資料庫篩選軟體為目標，從原始星象料庫中，濾除雙星、高等星星體，配合選擇星體演算法，以組成隨載星體資料庫，協助星象追蹤儀開發。本文所使用的三角網格分割演算法目的在解決將星體均勻分布於天球問題。為了比較均勻星體資料庫演算法優劣，我們也實現了其他均勻星體資料庫演算法，探討所選星體資料庫均勻度差異。
摘要(英) The main purpose of thesis is to set up an onboard star catalog selection software, which is sieve out those stars with insufficient brightness and binary stars from original star catalogs. The onboard star catalog selection software constructs the star catalog with uniform guide star selection algorithm for star tracker. The purpose of triangular grid division algorithm is to distribute stars uniformly on the celestial sphere. For compare the distribution of stars, we also realize other guide star selection algorithm.
