In this study, six campaigns around Anping tide gauge, Tainan, were successfully performed and the collected GPS buoy data were processed with four types of precise ephemeris provided by IGS, including final product, rapid product, ultra-rapid product and ultra-rapid product with the use of PPP technique. Comparing the PPP results with DGPS, the differences reach 3~5 cm in the horizontal and 10 cm in the vertical with final product; 6~8 cm in the horizontal and 15 cm in the vertical with rapid product; 15~20 cm in the horizontal and 30~40 cm in the vertical with ultra-rapid product; 2~3 m in the horizontal and 3~4 m in the vertical with ultra-rapid product. In addition, the collected data were also processed by DGPS techniques using different reference stations to analyze the effect of various baselines. The results show that accuracy degrades when the baselines increase.

本研究在台南安平潮位站旁进行6次GPS浮标施测，首先利用与GPS浮标距离不同之GPS参考主站来进行差分定位，分析基线距离对GPS浮标定位成果的影响，由实验结果可得出基线越长则定位准确度越低；再以IGS提供之最终产品、快速产品、超快速产品(Ultra-Rapid product)之观测部分observed half、超快速产品(Ultra-Rapid product)之预估部分四种不同发布延迟时间的精密星历与精密时表改正资料对GPS浮标进行精密单点定位解算，与传统差分相对定位方法定位结果进行比较后，得出使用最终产品之平面方向均方根误差(Root Mean Square Error， RMSE)可达3~5公分，而高程方向均方根误差可达10公分；快速产品之平面方向均方根误差可达6~8公分，而高程方向均方根误差可达15公分；超快速产品观测部分之平面方向均方根误差可达15~20公分，而高程方向均方根误差可达30~40公分；超快速产品预估部分之平面方向均方根误差可达2~3公尺，而高程方向均方根误差可达3~4公尺。

In this dissertation, GPS baseline solution precision is analyzed since the following aspects: 1, Different length baselines are processed and analyzed by single frequency model and ionosphere free model. 2, Basing on current single point positioning precision, certain coordinate error is added into fixed points to study the result. 3, Baseline is processed and analyzed with different observation vectors and their lineal combination models. 4, 24 hours observation was divide up to process baseline.

本文从以下几个角度研究了影响GPS基线解算精度的因素：1、采用单频和消电离层模式对不同长度的基线分别解算，对处理结果进行分析。2、根据目前单点定位精度给起始点加上适当的坐标偏差，研究起始点坐标偏差对基线处理结果的影响。3、选用不同的观测值及其线性组合，对基线解算结果进行研究。4、对24小时观测的数据分时段处理，分析观测时间段对基线处理结果的影响。
