中文摘要 | 本文運用全球衛星定位系統(Global Positioning System, GPS)之技術,以靜態觀測的方式,使用12臺GPS衛星接收儀,每15秒蒐集一筆觀測資料連續同步接收4小時,在臺東地區進行:(1)僅使用鄰近之上級控制點(一等衛星控制點);(2)僅使用相鄰之同等級控制點(二等衛星控制點);(3)使用相鄰以及鄰近所有同等級之控制點;(4)在第(3)項試驗中,加入鄰近之上級控制點等4項下同作業形式之二等衛星控制點補建試驗。由4項不同試驗形式得知,其在點位之平面坐標成果上並無顯著之差異。故本文發現,以第(2)項之補建程序進行衛星控制點之補建作業,不但能適當地降低測量外業施測成本並可兼顧補建作業之有效性。 |
英文摘要 | This paper studies the use of Global Positioning System (GPS) for reconstruction of second-order satellite control points in the Taidong area. Four reconstruction test modes were conducted: (1)only use the surrounding first-order satellite control points; (2)only use the adjacent second-order control points; (3)use all of the surrounding and adjacent second-order control points; (4)use all of the surrounding and adjacent second-order control points plus surrounding first-order control points. Experimental results from the four different reconstruction processes are compared, and no significant differences in horizontal coordinates are found. In conclusion, it is recnmmended that the reconstruction procedure (2) to be used in Taiwan for its capability to effectively reduce the cost of field surveying as well as maintain the quality of the reconstruction mission. |
