摘　　要：首先介绍了TEQC软件的功能及评价体系,其次利用TEQC软件对陕西省25个GNSS连续运行基准站2012 ～2013年观测数据质量进行了评价与分析.结果表明：①利用TEQC软件进行GNSS数据质量评价行之有效;②陕西省25个GNSS连续运行基准站观测数据质量良好,满足中国地壳运动观测技术规程的要求;③泾阳、山阳、太白、延安、西安基准站数据质量较差,主要与环境干扰和仪器故障有关.First, the features and evaluation system of TEQC software are introduced;secondly, the quality ofGNSS observational data in Shaanxi province from 2012 to 2013 is evaluated and analyzed by the TEQC software. The results showed that ： （1）It＇ s an effective way to evaluate the GNSS data by the TEQC software ;（2）Theobservational data quality of 25 GNSS Continuously Operating Reference Stations is good in Shaanxi province,which is satisfied with China Crustal Movement Observation technical specification requirements;（3）The dataquality of Jingyang, Shanyang, Taibai, Yan＇ an,Xi＇an reference stations is poor,it may be related with the environmental interference and equipment failure.
