For some reason(s) not clearly understood yet, as our other Ashtech Z12-T OPM2 was not affected simultaneously, the generation of Rinex files was not completed properly, or may have been completed but with partly corrupted files as a result. It is not only due to a problem in the file names, issued from the change from 2009 to 2010, which seems to have affected also some other Ashtech receivers in the IGS network, but also to a wrong GPS week number for half of one given day. Therefore, we had to spend some time trying to fix these problems. The Rinex files for the first three days of year 2010, which could only be partly rebuilt, have been resubmitted today to IGN. Please feel free to contact us in the case more detailed information would be needed. Best regards.
