Description

Dear GRAS SAF GTS User Issued: 2010-07-20 10:45 UTC There were no interruptions in connection with the GRAS Ground Support Network update earlier today. Please see detailed message from EUMETSAT below. Kind regards The GRAS SAF Team Forwarded Message: Subject: RE: Upgrade of GPS orbit processing for GRAS - finished! From: Christian Marquardt Date: 2010-07-20 09:28 UTC Dear all, the upgrade of the GRAS Ground Support Network (GSN) was smoothly carried out earlier today; no problems or any interruption of the GRAS level 1 processing occurred. The new version of the GSN auxiliary data became available for measurements at and after 06:09:00 UTC (on 20/07/2010). For a short period of time (06:39:00 UTC), the GRAS data processing operated on predicted Metop orbits, so there a small chance of having a few degraded occultations during this period. For measurements at and after 06:39:00 UTC, the GRAS processing used an orbit with nominal quality again, and the radio occultation data quality also appears to be fine. Thanks to our kind colleagues from GSN at ESOC who made this switch a really nice and painless experience - and also to those here at Eumetsat who helped us a lot as well (Yago and Andreas, that's you!). Kind regards, Christian. -- Dr. Christian Marquardt, Polar System Product Expert EUMETSAT, Am Kavalleriesand 31, D-64295 Darmstadt, Germany
