However, this change was not reflected in the header records of the RINEX files, which still included the old antenna number (177). Therefore, the data for days 128 - 132 have been resubmitted with the correct antenna serial number (222). Also, an additional file for day 127 was sent out today, which arrived with some delay. So, in fact the NTUS station has been operational again as of day 127 with the new antenna. Although the station is tracking again, it appears there are still some problems. During certain periods of the day, the station is tracking less satellites than it should, which leads to an estimated data loss of 10 to 30 percent. This problem is currently under investigation by Danny van Loon who will visit the station this week. We will keep you posted on the latest developments.
