摘要
国家测绘地理信息局现代测绘基准工程项目使用Trimble NetR9作为核心采集设备,在国家GNSS连续运行基准站上安装运行。Trimble NetR9和GNSS-Ti Choke Ring天线组合作为近年来国家级大项目使用最多的GNSS采集设备,其高稳定性、高可靠性、高精度的特性保证了项目的连续运行以及国家大地基准体系的完善和发展。
As the core acquisition equipment of modern geomatics engineering project of National Administration of Surveying,Mapping and Geoinformation of China,Trimble NetR9 was installed in GNSS continuously operating reference stations（CORS）. The antenna combination of Trimble NetR9 and GNSS-Ti Choke Ring is the most used GNSS acquisi-tion equipment in recent years’national project for its high stability,high reliability as well as high precision. It ensures to keep projects running smoothly and improves and develops the national geodetic datum system.
