| Summary: | 碩士 === 國立成功大學 === 民航研究所 === 95 === The objective of this thesis is to investigate the satellite navigation performance with the observation data from APEC Global Navigation Satellite System (GNSS) Test Bed (GTB). With the long term observation data from several GNSS monitoring reference stations and the information from the master station, this research can evaluate the GNSS performance in Taiwan under APEC GTB architecture. The evaluation criterion is the precision approach of APV I (Approach with Vertical Guidance). Additionally, this research collects the GNSS observation data from two additional networks to compare the ionosphere effects with data from APEC GTB, and they are the Ministry of Interior GPS network and the SOPAC GPS network. As part of this work, we conduct the trade-off studies of the ionosphere model by changing the separation of the ionosphere grid point, the sampling region, and iteration method. Finally, the performance results of this test bed provided by this thesis suggest that more resources should be focused on the improvement of the master station algorithm.
