Dear all,



an in-plane manoeuvre is planned for Metop-A next Wednesday, 18/07/2012, around 13:05 UTC. As usual, the operational processing of GRAS data will reset its Precise Orbit Determination system, and GRAS data will be of degraded quality for 4-5 hours after the manoeuvre has taken place. The quality degradation will also affect level 2 data produced by the ROM (formerly GRAS) SAF. The data will be flagged accordingly.



We will let you know when data quality is back to nominal again.



Thanks for your understanding,



 Christian.
