【摘要】：随着GPS技术的发展,其在社会各个领域已经得到了广泛的应用。目前如何利用GPS实现高精度定位定轨是国内GPS研究的一项重要内容，并且也已经取得了丰硕的成果。虽然目前国内有很多GPS静态数据处理软件，但是对于某些高精度的工程需要，如国家A级网联测、长基线等，很难达到我们实际工程的精度要求。因此有必要引入国外的GAMIT和Bernese高精度软件。论文主要从GAMIT与Bernese软件的结构与特点、两软件在结构与功能、参考框架的选择、相位中心模型的选取、先验坐标的选取、模糊度解算方法等方面进行了比较分析，，来研究两款软件实现精密定位定轨的原理与方法，对比两软件的优缺点。论文主要包括两部分：第一部分通过对IGS站的数据进行对比分析，从而为我们解算实际工程数据提供理论参考依据；第二部分利用两软件对某地区B级网数据进行处理以及对比分析，而且还可以相互检核，从而实现了高精度定位。总之，论文的主旨是通过两软件的研究，理解高精度定位的原理与方法，实现高精度定位。
[Abstract]:With the development of GPS technology, it has been widely used in various fields of society.At present, how to use GPS to achieve high precision positioning and orbit determination is an important content of domestic GPS research, and has also achieved fruitful results.Although there are a lot of GPS static data processing software in our country, it is difficult to meet the precision requirement of our actual project for some high precision engineering requirements, such as national A-level network connection survey, long baseline and so on.Therefore, it is necessary to introduce foreign GAMIT and Bernese high precision software.The structure and characteristics of GAMIT and Bernese software, the selection of reference frame, the selection of phase center model, the selection of prior coordinates and the method of ambiguity resolution are compared and analyzed in this paper.The principle and method of precision positioning and orbit determination are studied, and the advantages and disadvantages of the two software are compared.The thesis mainly includes two parts: the first part provides the theoretical reference for us to solve the actual engineering data by comparing and analyzing the data of IGS station;In the second part, two softwares are used to process and compare the data of a certain area's B-level network, and they can also check each other, so that high precision positioning can be realized.In a word, the purpose of this paper is to understand the principle and method of high precision positioning through the research of two softwares.
