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。

Most of the developing X-Y tables applied Ball screw-driven table system or piezo-ceramic linear motor by taking the advantages of carrying heavy loads. However, their cost are very high in contrast to the proposed architecture. In some particular application fields. Carrying heavy loads is not the main requirement for the X-Y table, such as organic cell inspection, optical fiber alignment, nano-material research, ect. Taking this idea as a premise, if we could able to create a precise positioning X-Y table with very low cost, we will be able to achieve the extremely high commercial value and highly competitive ability.

X-Y精密定位平台的开发，不外乎线性马达或压电陶瓷马达搭配导螺杆或其它机构所组成，其优点是可以承载较重之待测物体，缺点是重量大且价格昂贵，在许多应用上并不要求测试平台拥有太大的荷重能力，如生物医学诊断及检测，生物晶片开发及检测，光纤校准，奈米材料研发，奈米量测及精密全平面扫描等等，如果以此为前提，能以极低之成本创造出高精密定位之X-Y平台，将会有极高之商业价值及极大之竞争力。
