【摘要】 全球卫星定位系统(GPS)是一个实时的,全天候,全方位的定位系统。设计此系统的最初目的只是为美国军事服务,如今却已扩展到诸多民用领域,包括民用导航与监控,交通管理,测绘科学与技术,土木工程,空间科学等等。随着全球定位系统的不断改进,硬、软件的不断完善,应用领域正在不断地开拓。本文针对GPS的特点,介绍了一套比较基本的完整的GPS相对定位数据解算方法。利用GPS接收机所采集的数据,进行卫星位置的计算,用多项式拟合与载波相位双差观测值相结合对周跳进行探测与修复;介绍了几种求解模糊度的方法,重点分析了LAMBDA方法,通过计算机仿真,认为LAMBDA方法是确定整州模糊度比较有效的方法;利用精确载波相位观测值根据GPS测量定位方法及原理,介绍了载波相位定位技术,包括单差模型、双差模型以及三差模型,最后介绍了利用布尔沙七参数法进行不同坐标系下的坐标变换,更多还原

【Abstract】 Global Positioning System (GPS) is a real-time, all-weather, full range of positioning systems. The original objection of designing such system is only servicing for military, but now it has been extended to many civilian areas, including civil navigation and control, traffic management, surveying and mapping science and technology, civil engineering, space science and so on. With the continuous improvement of the global positioning system, perfective of hard and soft parts, applications are constantly developing. In this paper, according to the characteristics of GPS, introduces a more integrity method of data solution about relative positioning, using the data that collected by GPS receivers to calculate the satalite position, combining polynomial fitting and double-difference carrier phase observations to detect and repair cycle slip. This paper introduces several methods for solving ambiguity, especially analys LAMBDA method, by computer simulating, that the LAMBDA method is the best way to solve ambiguity. With the using precise carrier phase measurements and basing on GPS positioning method and principle, introduces carrier phase positioning technologies, Include single model, double model and three model . At last,according to the needing of project, introducing using BURSA 7-Parameter Transformation to change the coordinate of different coordinate system.更多还原
