The data flow was interrupted at that time. Today, the USNO data using the new receiver have been uploaded to the IGS, starting with doy 072 (13-MAR-2002). This receiver is now reporting both daily and hourly data files to the IGS. (Actually, the raw data are being collected at a 5-second rate and offloaded very 30 minutes. The IGS files are formed from those.) A new site log is posted at the IGS Central Bureau. The help of Ernie Marion (NOAA/NGS) and Paul Wheeler (USNO/TS) was critical in making this change. I would also like to thank Miranda Chin (NOAA/NGS) and her colleagues for making the necessary changes to the data offload processing. I apologize for any inconvenience caused by the interruption in data from this station.
