摘要
本文首先对影响 GPS 外业观测质量的因素进行了分析，并介绍了TEQC的使用情况。对西宝和成贵两个项目GPS数据进行了预处理，获取了数据质量信息，直接反映出外业数据的真实质量情况，这后续计算成果的真实性、可靠性更有把握。
This paper firstly analyzed factors affecting the qu-ality of GPS field observation, and introduced the application situation of TEQC. The author preprocessed the data of two projects of Xibao and Chenggui, acquired the information of data quality which directly reflected the true quality of field observation data, thus, the authenticity and the reliability of the subsequent calculation results were more reliable.
