摘要

結合動態OTF(On-the-Fly)相位未定值演算法與通訊設備的GPS即時動態測量(Real Time Kinematic, RTK)，能夠在運動狀態下求解相位未定值，且可進行即時定位，大幅縮短了一般GPS靜態測量所需的時間。本文主要針對RTK系統原理、應用於控制測量與戶地測量之定位精度、基線長度與可靠度之關係等方面進行探討與規劃，並佐以地籍重測區戶地測量實驗之驗證。最後針對RTK成果的檢核，研擬提高可靠度的方法，以確保測量成果之可靠。

The combination of OTF (On-the-Fly) phase ambiguity resolution method and GPS RTK (Real Time Kinematic) surveying design enables instantaneous solution of phase ambiguities in a moving situation. Such a RTK system needs only few observation epochs to perform positioning, so it is able to reduce the time needed for GPS surveying. This paper discusses the application of RTK system on control survey and cadastral survey, with emphasis on the accuracy issue and the relationship between baseline length and positioning reliability. Several experiments in cadastral survey are completed. This study also presents the schemes to increase positioning reliability, in order to preserve the centimeter level UPS surveying accuracy.
