dc.description.abstract | 單一參考站即時動態定位測量之理想水平及垂直精度分別為10mm 2ppm及20mm 2ppm,但在實際作業時受到基線長度、觀測時段、參考站位置、大氣條件、電磁或其它干擾等因素的影響,往往會大幅降低其觀測精度。基於即時動態測量(RTK)之技術所具有之機動性、即時獲得精確點位坐標等特性,大幅縮短一般GPS靜態測量所需的時間,將即時動態理論應用於地表之監測可達到精確、快速的變位監測,以期當三維方向的位移量產生後立即了解各方向的地表位移情況。 本研究以三個設置於穩固不易變動點位上的參考站組成GPS網絡,利用模擬即時動態定位的方法進行資料解算,並就單一參考站RTK定位與VRS技術解算之成果加以比較與分析。於基線長度約30公里的情況下,使用虛擬參考站(VRS)的成果確實優於單一參考站RTK定位,可以大幅減少因基線長度增加而增加之電離層和對流層誤差影響量,提供一定精度的定位成果,也是傳統三角三邊測量、水準測量和靜態GPS測量所無法達到的即時性監測。 | zh_TW |
dc.description.abstract | The precision of the RTK is 10㎜ ±2ppm for the horizontal and 20㎜ ±2ppm for the vertical distances. However, these precisions are limited when the baseline distance is shorter than 10㎞. In many actual conditions , the distance of a baseline is much more longer than 10㎞, may be 30, 50, even it 70㎞. Therefore, the precision of a long baseline of RTK is a hot study topic for RTK users. This paper aims to study the precision of a baseline whose distance is more than 30㎞. Using more than three reference stations, a virtual reference station (VRS)can be produced for RTK surveying . From the results, the precision of the VRS is better than traditional RTK which has only a single reference station. | en_US |
