1、毕业论文-GPS数据处理研究本科学生毕业论文GPS数据处理研究院系名称专业班级学生姓名指导教师职称二○一二年六月TheGraduationThesisforBachelorsDegreeStudyonDataProcessingofGPSCandidateSpecialtySurveyingEngineeringClassSupervisor2012-06·Harbin摘要GPS技术作为一种全新的测量手段在国家大地网城市控制网工程控制网的建立与改造等方面已经得到普遍应用其技术的先进性优越性已为众多科技工作者所认同高等级高精度GPS控

2、制网一般指范围较大精度较高的一类控制网它可以是局部网国家基础网地震监测网甚至全球网这类网一般点数较多点间距较长几十几百公里或上千公里例如总参测绘局布设的GPS一二级网国家测绘局布设的AB级网用于地震预报的地震监测网各省市的AB级网连续运行参考站系统的基准站网等结合在测量工程中应用ASHTECH和TRIMBLEGPS接收机的实践本文主要说明了GPS数据处理过程中对基线向量解算的人为干预处理独立边的选取闭合环检查限制GPS网的投影长度变形及其成果的检验问题在针对相关工程项目中对GPS数据处理的应用做了相应的分析对比结合天宝TGO徕卡LG
