摘　　要：甘肃省卫星定位连续运行基准站网用户坐标系服务系统是甘肃省现代测绘基准体系的重要组成部分,实现了不同坐标系间相互转换,提供大地高和85高程之间相互换算服务,文中以两个算例分析确定坐标系转换关系。The service system of user coordinate system transformation on GSCORS was an important part of the modern surveying and mapping benchmark system in Gan Su. Transformation between different coordinate systems was implemented,and the conversion between Geodetic Height and 1985 National Height was provided. In the paper,the main technology characteristics of project implementation were introduced.
