摘　　要：美国Trimble Geomatics Office(TGO)GPS数据处理软件被测绘工作者广泛使用,但因其对环闭合差的检核是用水平分量和垂直分量表达,不能按我国GPS规范,分别对同步环及异步环以三维坐标分量方式检验环闭合差,而给使用带来极大不便。本文提出利用TGO的环闭合差报告和数据交换文件中的有关信息解决此难题,用VB编写成TGO辅助程序加以实现,并与不同的软件进行比较分析,说明该程序可以应用于工程实践中。The Trimble Geomatics Office（TGO）software which is used for GPS data processing is widely used by the measurer.While in software,to check the loop closure is expressed by the horizontal and vertical components separately.For implementing the relevant criterion（GPS） about to calculate loop closure of Simultaneous loop and Independent loop with 3D coordinates of China＇s component mode,the solution was raised out in this paper.The realizing process is to utilize the relevant information of the loop closure report and date exchange,the auxiliary programme of TGO was written by VB language,at the same time,the program was compared and analyzed with different software,stating that the program could be applied in practical engineering.
