起算点对GPS控制网的影响及质量控制
|
摘要
针对GPS在山区石油地震勘探测量中的工作方式,结合2011年桂中地区2维地震资料采集项目和近几年物探测量项目应用GPS布设控制网的工程实例,分析起算点对GPS控制网平差结果的影响。从起算点的选取和分布、外业观测、基线处理到约束平差各个环节综合考虑,优选点位,合理设计,降低由于起算点的原因引起的误差,提高GPS控制网的质量。
The paper analyses the impact and quality control of the starting points on GPS control network based on the technique of GPS used in the petroleum seismic exploration in mountain areas and the application of GPS to control net placement in the geophysical exploration project of Guizhong region in 2011.The paper intends to take into account various factors of starting point selection and layout,field observation,baseline processing and constrained adjustment to optimize the design,reduce the error possibility and ultimately improve the quality of GPS control network.
