| Summary: | 碩士 === 國立成功大學 === 測量及空間資訊學系 === 102 === As the Chinese BeiDou Navigation Satellite System (BDS) has been announced to provide operational service over the Asia-pacific region, it will increase the number of satellites in view and will have a significant effect on ambiguity resolution (AR) for fast and high-accuracy positioning. Thus, it is important to better understand and demonstrate the capabilities of the GPS/BDS combined system. In this thesis, numerical analysis is given to the single-epoch AR and RTK positioning capabilities of the GPS/BDS combined system. This study focuses on dual- and triple-frequency AR by using DCAR, TCAR and generalized DCAR/TCAR methods, and compares the performance between standalone and combined systems. Compared to the performance of GPS-only and BDS-only systems, the GPS/BDS combined system can increase the success rate for single-epoch ambiguity resolution and provide high accuracy RTK positioning.
