| 中文摘要: |
| 我国测量规范对GPS测量外业数据质量检验对象是三维坐标分量，而大多用户使用的平差软件（TBC）的检验对象则是水平分量和垂直分量。如何以三维坐标分量方式统计环闭合差并区分同步环及异步环是应用TBC软件必须解决的问题，目前国内尚未发现针对TBC三分量闭合差计算的商业软件。结合港珠澳大桥珠澳口岸人工岛GPS控制网工程实践，给出编制GPS外业观测质量检核软件可行的方法。 |
| 英文摘要: |
| According to the relevant GPS codes of our country, the method of loop closure checking is used to calculate 3D coordinate components separately. While in Trimble Business Center (TBC) software, the method of loop closure checking is to calculate the horizontal and vertical components separately. How to calculate the loop closure with 3D coordinate component mode and how to distinguish simultaneous loop and independent loop is an important issue for implementing the required Code under TBC software. The paper is to discuss how to design the GPS field data quality program to solve the problem. |
