摘　　要：福建省CORS系统是地球空间信息服务的重要基础设施,是当代GNSS发展的热点之一。结合工程实际,并综合利用陆态网络观测数据,设计出三种不同方案,对沿海大地控制网进行解算。结果表明,三种方案均具有较好的可靠性,坐标中误差数据显示,由于利用1σ约束CORS站点作为控制的解算方案,大大缩短了基线长度,并使图形结构更加合理,能够获得较强约束陆态网络基准站作为控制方案更好的测量精度。Fujian Province CORS system for achieving modernization, popular, is an important infrastructure of the contemporary GNSS development intensive, high quality geo-spatial information services. Based on engineering practice, and do comprehensive utilization of land state network observation dates, we designed three different programs to realize the resolution of the coastal geodetic control network. Results show that, this three schemes have the same reliability, the coordinate error data shows the scheme of 1 o＂ constraints to the CORS site has a better measurement accuracy comparing, the scheme of strong constraints to the land state network base station, because of the shorter of baseline and more reasonable of graphical structure.
