Abstract

To adopt teqc software to carry out comprehensive detection and assessment on 49 continuous running observation stations from the JLCORS network system, including data integrity, ionospheric delay and variability, multipath effect etc. Besides, data sampling rate adopts 30 seconds and the satellite cut-off angle is 10 degrees. The result reveals that 95% observation station sampling efficiency is between 0.9 and 1 and 80% CSR value is between 0.0 and 0.35; the RMS of the MP1, MP2 is between 0.15 and 0.45m and the maximum value of MP1 and MP2 is 0.45m of SLAN station and 0.42m of DEFN station. The operating condition of receiving set is good and detection environment as well as data are in accordance with the requirements of Technical specification for Crustal Movement Observation Network of China and are better than the standard of international IGS station. In addition, we carry out statistical analysis on the time interval with serious delays in terms of ionosphere as well as unhealthy satellite so as to provide reliable foundation for GNSS post-processing.
