摘　　要：为了完成某单基站CORS播发CGCS 2000坐标基准服务,同时也为建立2000国家大地坐标系与某地地方坐标系的转换关系,应用GPS技术,通过联测原有高等级控制点,利用精密星历,求解出站点坐标值,并计算出转换参数。实验表明,利用求得的七参数、接收单基站播发的2000国家大地坐标基准,可以达到一级导线的精度,满足常规工程测量需求,可为其他类似工作提供参考。In order to complete the CGCS 2000 coordinate benchmark service of a single base station CORS broadcasting,and to establish the conversion relationship between CGCS 2000 and local coordinate system of a certain place,GPS technology is used to measure the original high-level control points,calculate the coordinate value of the station and the conversion parameters based on precise ephemeris.Experiments show that based on 7 known conversion parameters,the accuracy of the first-level traverse can be achieved by using the CGCS 2000 datum broadcasted by a single base station,which can meet the requirements of conventional engineering surveying and provide reference for other similar work.
