摘要

本文的研究方向在高效率且具高精度的定位方式，因此包含快速靜態定位及動態定位。文中利用約六十米至二十六公里的基線分析快速靜態定位的定位精度，動態定位則利用一約十公里的基線驗證其可行性及定位精度，並選擇一衛星高程測量案，實際驗證衛星定位的成效：用於5x6 km^2，平坦實驗區的25個檢核點時，快速靜態及動態衛星測量分別獲得±1.1cm及±1.3cm的高程精度。另外，特別針對時鐘偏差量提出一套解相關的做法，當應用此做法於Ashtech 3DF的資料上時，於該實驗例可大幅提昇高程精度。

In this paper we study the positioning technologies which have high efficiency and precision, therefore our objects of study include both rapid static positioning and kinematic positioning. We analyze the rapid static positioning by various baseline length from about 50m to 26km, and evaluate the kinematic positioning with respect to its repeatability and feasibility by a baseline of about 10km. These technologies are applied to satellite leveling and experimentally verified. For 25 check points in a 6kmx5km flat test area, the rapid state and kinematic satellite surveying technologies can yield ±1.1cm and ±1.3cm height accuracy. Besides, a technique of the decorrelation method to improve the accuracy by calibration the receiver clock bias is offered in this paper, and using Ashtech 3DF data to prove it. From experiment we know the height component is improved about 300%.
