Subject: GRAS product quality degradation yesterday, 4th January 4 2011

Dear all,

first of all: A Happy New Year!

Unfortunately, the operational GRAS processing experienced a reset of its Precise Orbit
Determination component around noon yesterday, 04/01/2011. As usual, this reset was 
followed by a period exhibiting degraded level 1b (and higher) data quality, and data has 
been flagged accordingly for 4 hours (until about 16:30 UTC) after the event.

We are currently investigating the cause of the reset and will of course do what's needed 
in order to to avoid future re-occurrences if possible. 

And we apologize sincerely for any inconvenience this renewed glitch in our processing 
might have caused on your side.

With kind regards,

 Christian.
