【摘要】 研究和论述了区域地面沉降高精度GPS监测数据处理方法的主要流程和其中的关键技术问题,提出了针对区域地面沉降高精度GPS监测中GPS基线向量解算和网平差等问题的一系列严密数据处理方法和措施,并用这些方法和措施对某区域2007-2009年的地面沉降GPS监测数据进行了计算、处理和分析。研究结果表明,用本文提出的高精度GPS数据处理方法可准确、可靠地获取该区域地面沉降的变化信息,并发现该区域内已存在三个明显的地面沉降区,且表现出持续沉降的特点。更多还原

【Abstract】 The main processes and some key problems of high precision GPS data processing were studied and discussed on regional land subsidence monitoring,and a series of strict methods and measures of GPS data processing such as GPS baseline vector solving and network adjustment were proposed.Then those methods and measures were used to process and analyze the GPS monitoring data on an area that had occurred land subsidence from 2007 to 2009.The studying results show that the deformation information can be acquired exactly and reliably by those methods and measures proposed by this paper.In the mean time,three places occurring land subsidence obviously are detected and the characteristics of continual subsidence are displayed in this area.更多还原
