摘　　要：随着全球导航卫星系统(GNSS)的广泛应用,利用GNSS建立控制网成为测绘项目基础控制的主要作业方法之一。本文以珠海市D、E级GNSS加密控制测量为例,给出了在点位分布极其不均、跨陆海联网等复杂条件下的GNSS加密控制网布设方案和数据处理策略。With the wide application of Global Navigation Satellite Systems(GNSS),the use of GNSS to establish control networks has become one of the main operational methods for basic control of surveying and mapping projects.In this paper,taking the control measurement of grade D and E GNSS densification in Zhuhai city as an example,the layout scheme and data processing strategy of GNSS densification control networkunder complicated conditions such as extremely uneven distribution of points and land and sea networking are proposed.
