| 摘 要： | 连续运行卫星定位服务系统(简称为CORS)已经在国内外广泛建立,CORS在维护区域大地测量基准和城市测绘工作中得到了非常广泛的应用。但在城市地面沉降监测方面,仍存在基准站的稳定性、测量精度对平面及高程形变影响等问题。这里提出了一套完整的基于CORS系统变形监测网的稳定性分析的方法和流程。采用秩亏自由网平差,以位移向量一次性范数最小原则求取监测网点最合理的位移量及权阵。采用正态分布函数对监测点的位移显著性进行检验。结合武汉市地面沉降监测项目,分析评价了武汉市连续运行卫星定位服务系统(简称为WHCORS)用于城市地表形变监测的可行性。

| Abstract: | CORS have been widely established at home and abroad,and have been used in geodetic measuring,coordinate system retaining and surveying and mapping of city.However,some questions(stability of fiducial stations,influence of survey precision on horizontal and vertical extension,et al)are still unresolved in urban land subsidence monitoring.Based on the CORS,a method and flow for data processing and stability analysis of deformation monitoring network was proposed.Using rank defect free network adjustment,a ro... |
