摘　　要：通常情况下,RTK手薄使用的2000国家大地坐标系和1980西安坐标系,二者间的转换参数为4参数,适用控制区域面积小,一般不能超过20 km×20 km,不利于RTK大区域作业。为满足基于河南省连续卫星运行参考站(He NCORS)的RTK大区域作业需求,文章对适用于河南省行政区域的Bursa 7参数求取方法和实际应用等技术进行了研究。通过实践验证,得出一组适用全省的2000国家大地坐标系与1980西安坐标系的Bursa 7转换参数,并以Trimble TSC2手薄为例介绍其使用方法。In general,the conversion parameters between the 2000 National Geodetic Coordinate System and the1980 Xi＇an Coordinate System used in the RTK field books are four-parameter for a small area within a range of 20 km ×20 km,which is not conducive to the operation of RTK in a large area. To meet the operational needs of RTK based on Henan Continuous Satellite Operation Reference Station（He NCORS） in a large area,the paper has studied the extraction method sand practical application of Bursa seven-parameter. Practice indicates that the parameter can be applied in Henan province,and the use of Trimble TSC2 field books as an example is introduced.
