Zhang Yong-q · Plateau Earthquake Research · 2014
First,the features and evaluation system of TEQC software are introduced; secondly,the quality of GNSS observational data in Shaanxi province from 2012 to 2013 is evaluated and analyzed by the TEQC software. The results showed that: ①It's an effective way to evaluate the GNSS data by the TEQC software; ②The observational 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; ③The data quality of Jingyang,Shanyang,Taibai,Yan'an,Xi'an reference stations is poor,it may be related with the environmental interference and equipment failure.
