Analysis and comparison of GNSS data quality in CORS network of Shanxi Province based on TEQC
This paper utilized the observation data from each station of the continuous operational reference system(CORS)in Shanxi Province and carried out quality inspection research on the observation data based on different versions of data preprocessing software,namely translation,editing and quality checking(TEQC).The results indicate that the new version of TEQC has more stable inspection results.The theoretical observation epoch number of multi-satellite system data is relatively large at cut-off altitude angles of 15° and below.At cut-off altitude angles of 15° and above,the influencing factor of the adverse satellite is greater than that of the cut-off altitude angle.The difference analysis results of TEQC in different versions can provide certain application reference values for global navigation satellite system(GNSS)data preprocessing and baseline calculation.
