Sinex products for GPS week 1298 is resubmitted, and products for GPS week 1299 to 1308 is submitted with delay. Time series of station coordinates in our products showed a large gap at GPS week 12982. SNR flags in rinex files of IRKT changes to lower values at the week, and GAMIT AUTCLN eliminates the data as bad data. We reanalyzed the data after changing a AUTCLN parameter for SNR flag in order to include data with lower SNR flags. The results doesn't show any gaps and rms seems to be improved.
