GPS变形监测网网形结构对控制网质量的影响

为了分析GPS控制网网形结构与控制网质量的关系,在论述衡量GPS变形监测网的精度、可靠性、灵敏度、费用4个质量标准的基础上,根据GPS控制网的特点,分析了基线数及其连接方式等网形结构对GPS控制网精度、灵敏度的影响.以一高边坡监测网为例,说明GPS控制网基线数不同,控制网的质量不同;基线数相同,不同的连接方式质量也不相同.

Effect of GPS deformation monitoring network structure on quality of control network

In order to better understand the relationship between the structure and quality of a GPS control network in terms of the four quality standards of precision,reliability,sensitivity and cost,the effects of network structure on precision and sensitivity of a GPS deformation monitoring network were analyzed according to the characteristics of the GPS network.Using a high slope monitoring network as an example,the results show that the quality changes with the number of baselines,and that if the number of baselines is the same,the quality changes with the connection type.
