無人機廣泛應用於各場域，如何具有穩定的精準定位將會是一項重要的課題。GPS技術發展至今已非常進步，無人機方面目前也常用RTK作為輔助以提升定位精度，而網路RTK發展亦逐漸成熟，台灣也完成建置以網路RTK發展的e-GNSS系統。內政部國土測繪中心建置的e-GNSS系統之即時動態定位服務，使用者在地面站中連網並使用NTRIP通訊協議即可使用，在保有高精度的狀況下，增加執行任務的方便性與穩定性，本研究目的是使用e-GNSS輔助飛行，並驗證其對於無人機飛行精度的表現狀況。透過研究結果分析可知，不論靜態與動態實驗，e-GNSS確實可以應用並提升無人機之飛行定位精度，與單主站RTK比較則是表現相當，但加入操作方便性考慮則是優於單主站RTK。

UASes are widely used in various fields nowadays, and how to have stable and precise positioning will be an important issue. The development of GPS technology has been very advanced so far, and RTK is also commonly used to improve positioning accuracy. The development of network RTK has gradually matured, and Taiwan has also completed the construction of e-GNSS system developed by network. The real-time Mapping Center of the Ministry of the Interior allows users to connect to the Ground Station and use the NTRIP communication protocol. It can increase the convenience of executing tasks while maintaining high precision and stability. The purpose of this study is to use e-GNSS system to aid flight and verify its performance for UAS flight accuracy. Through the analysis of this research results, e-GNSS can apply and improve the flight positioning accuracy of UAS, regardless of static and dynamic experiments. Compared with the RTK, the performance is comparable, but the convenience of e-GNSS is better than the RTK.
