长江干线D级GPS控制网的布设和数据处理

长江沿线的控制测量是进行流域规划和港口建设的基础性工作.由于涉及长距离测量和跨河测量,测量精度要求高,因此,常规的三角网、三边网工作量难以完成长江干线大规模的测量任务.GPS技术具有精度高、测量速度快、进行跨带测量简单的特点,通过实际测量工作,探索GPS技术在长江干线D级控制网建设中的应用及测量布设方案和数据处理方法.实践表明,测量结果完全达到国家标准.

Construction and Data Processing of D-evel Control Network with GPS Technology along Yangtze River Trunk

Control surveying along the Yangtze River is a basic work of basin planning and port construction.As it is a long-distance and river-crossing measurement,needing the high precision,the conventional triangulation and trilateration methods can hardly complete the large-scale measurement work along the Yangtze trunk.The GPS technology posseses the characteristics such as high accuracy and fast measuring speed,and is easy and convenient for cross-measurement.Through the actual measurement,the application of GPS...
