RTK應用於大型都會區圖根點新補建模式之研究

The Study of RTK Application Model in Constructing Control Point-A case of Taichung Experiment

目前RTK定位技術已經被廣泛應用於各種測量作業上，然因衛星訊號會受遮蔽影響，故並非所有地區均適用RTK測量進行作業。RTK衛星定位技術於都會區受建築物、地形等外在因素影響，在使用上並不如預期理想。本研究以臺中市設立之基站網為例，採用以RTK施行圖根點新補建時，移動站受到遮蔽時對RTK定位精度之影響及探討都會區受建築物及地形影響時，RTK使用之可行性進行研究；並另在RTK無法施測地區於選定點位附近選擇可以施測RTK點進行測量，並結合全測站經緯儀進行聯用之測試與研究，期使未來各縣市地政單位能快速、準確的測定圖根點位置進而正確、合理的釐整地籍資料。 The Global Positioning System (GPS) Real Time Kinematic (RTK) technique has already been used extensively in surveying engineering. The drawbacks of RTK technique are many factors such as signal obstruction of satellite and radio. Therefore the method of RTK technique is inconveniently to use in metropolitan district area. In this study, the positioning precision of the method of RTK will be discussed and analyzed in different ratio of obstacle in open sky and the feasibility of GPS RTK technique in the chosen test data-Taichung city. The coalition of RTK and total station will also be discussed in this study.
