摘要
GPS站点的观测环境对数据质量有较大的影响,但影响的规律和量级还有许多技术难点需要克服。利用TEQC软件,对全国7个省市的GPS控制网进行了初步分析,并结合数据处理分析了GPS观测环境和数据质量的相关性,得出了一些有益的结论。研究表明:通过GPS观测数据的分析,可以对观测数据进行初步质量控制,并作为观测数据验收和计算前的数据质量分析依据。
The environment of GPS site have a great influence on the data quality; however lots of the technical difficulties in the discipline and magnitude of the influence awaited to be overcome. Using the TEQC software, this paper makes a preliminary analysis of GPS control network in seven provinces and cities in china, and then makes a correlation analysis between GPS environmental condition and data quality by data. Some valuable conclusions are made. Research shows that under the analysis of GPS ob- servation data, preliminary quality control of the observation data can be accomplished, also it can be deemed as a standard of the inspection and quality analysis of the data before calculated.
