GPS系统的误差来源分析及性能分析
摘要
GPS全球卫星定位系统是美国国防部为满足军事部门对海上、陆地和空中设施进行高精度导航和定位的要求而建立的。该系统具有全球性、全天候、连续性等三维导航和定位能力,并具有良好的抗干扰性和保密性。它已成为美国导航技术现代化的最重要标志,并被视为20 世纪美国继阿波罗登月计划和航天飞机计划之后的又一重大科技成就。在航空、航天、军事、交通、运输、资源勘探、通信、气象等几乎所有的领域中,它都被作为一项非常重要的技术手段,用于导航、定时、定位和进行大气物理研究等。先对GPS的组成进行了解,在进行GPS的误差来源进行分析,最后研究GPS误差消除的方法和改进措施。GPS 系统的定位误差直接GPS定位精度,按其产生的来源、性质及对系统的影响等进行了介绍和初步,提出了相应的措施以便消除或削弱它们对测量结果的影响。误差讲直接影响我们的测量,所以研究了GPS消除误差方法。最后提出了改进措施。

Abstract
GPS global satellite positioning system (GPS) is the . department of defense for military services for land, sea and air facilities for high precision navigation and positioning requirement. The system has a global, all-weather, continuous 3 d navigation and localization ability, and has good anti-interference and secrecy. It has e the United States of the most important marks of modern navigation technology, and is considered a 20th century the United States after the Apollo mission to the moon and the space shuttle program after another major scientific and technological achievements. In aviation, aerospace, military, traffic, communication, transportation, resource exploration, weather, etc. Almost all of the areas in which it has been as an important technical method, used in navigation, timing, location and atmospheric physics and so on. First to understand position of the GPS, in the error sources of GPS is analyzed, finally the GPS error elimination method and improvement measures. GPS positioning error of the GPS positioning accuracy directly, according to its origin, nature and effect of the system are introduced and a preliminary, puts forward the corresponding measures to eliminate or weaken their influence on the measured results. Speak directly affect our measurement error, so the GPS method to eliminate error. Finally put forward the improvement measures.
