From jake.griffiths at noaa.gov Sun Feb 3 05:09:21 2013 From: jake.griffiths at noaa.gov (Jake Griffiths - NOAA Federal) Date: Sun, 3 Feb 2013 08:09:21 -0500 Subject: [IGSMAIL-6728] outage interrupts availability of IGS products Message-ID: Author: Analysis Center Coordinator Dear Colleagues, The servers that generate the IGS orbit and clock products have been unavailable for unknown reasons since yesterday evening, sometime before 22:00 EST (or 03:00 UTC today). As a result, there have been no IGS Ultra-rapid products generated since 1725_6_18. It is unclear how long it will take to restore IGS services. If they are not restored within the next ~3.5 hours (by ~16:00 UTC), then the generation and delivery of IGS Rapid products will also be interrupted (starting with 1725_6). We will continue to work to resolve the outage as quickly as possible. In the meantime, you may want to consider using the ultra-rapid and/or rapid products directly from one of the Analysis Centers (ACs). For example, the Swiss CODE group makes all their IGS contributions available at: ftp.unibe.ch/aiub/CODE/COD.EPH_U <- latest ultra SP3C, updated every 6h ftp.unibe.ch/aiub/CODE/COD.ERP_U <- latest ultra ERP, updated every 6h ftp.unibe.ch/aiub/CODE/CODwwwwd.EPH_R <- rapid SP3C ftp.unibe.ch/aiub/CODE/CODwwwwd.ERP_R <- rapid ERP ftp.unibe.ch/aiub/CODE/CODwwwwd.CLK_R <- rapid 30s CLK For more information about the CODE ftp contents, see: ftp.unibe.ch/aiub/AIUB_AFTP.TXT Please use any AC products with caution, as they are not official IGS products. They may contain observed and predicted orbits for unhealthy and unusable satellites. If your applications know not to use unhealthy/unusable satellites, then AC products should be usable for apps requiring ultra-rapid inaccuracies not less than ~3 cm (for observed part) and not less than ~5 cm (for predicted part), and rapid orbit inaccuracies not less than ~2 cm. Apologies for the inconveniences this outage will cause.
