MSG Primary Satellite

• MET-9 (MSG-2) satellite Image & Product Validation Review (IPVR) has concluded that the MET-9 satellite is ready to assume the role as primary imaging satellite.

• MET-9 was declared the primary satellite 11 April 2007 after a period of 1 month of parallel operations with MET-8 (MSG-1) .

Rapid Scan Service (1)

• EUMETSAT intend to use the back-up satellite from Jan 2008 to continue the Rapid Scan service provided by MTP from MET-8 located at 9.5º E, rectified to 9.5º E or 10º E.

• The rapid scan service will provide rapid scan cycles (RSC) over the upper third of the earth disk in 5 minute intervals. The following pattern has been selected as baseline: 11 sets of 26 days RSC + 2 days BRC, followed by 1 set of 28 days BRC. With BRC being the baseline (15 min) repeat cycle.

• SEVIRI data will only be available from the back-up satellite during RSC periods via EUMETCAST. All data will be available from UMARF.

Rapid Scan Service (2)

• The BRC full disk coverage periods will be timed to coincide with predicted outages of the primary satellite due to such things as decontamination or manoeuvres.

• 12-19 Feb 2007 the rapid scan service was successfully tested on MET-9 (MSG-2) at 0º

• Further rapid scan trials are planned for the rest of 2007 gradually building up to the full service. The next trials are planned for 11-28 May 2007 and 1 June – 31 August 2007.

MSG-3 satellite (no change)• Due to unavailability of vacuum test facility, the MSG-4 AIT

activities have been delayed. The MSG-3 activities have been re-started to correct issues and to complete open items raised at its Pre-Storage Review. An anomaly on the SEVIRI TM read-out has delayed the entry into storage.

• Launch planning: In July 2006, the EUMETSAT Council agreed to re-plan the MSG-3 launch for January 2011 . In case of outcomes from the LCL failure investigations leading to an early launch, Delegates will be informed accordingly, and launch date will be revisited .

• GERB-3 need date for satellite re-integration is January 2009 or earlier depending upon the LCL investigations. GERB-3 recalibration needs to be completed latest by end 2008.

MSG-4 satellite

• A confidence test between GERB-4 & MSG-4 has been performed. The instrument is currently integrated on MSG-4.

• The Pre-storage Review (PSR) has been initiated and the final report is under preparation.

• In July 2006, the EUMETSAT Council agreed to re-plan the MSG-4 launch in the mid-2012/mid-2013 time frame. To be defined at the time of MSG-3 destorage – Jan 2013 is used for planning purpose.

• GERB-4 need date for satellite integration is April 2009, as a spare for GERB-3.

GERB-1 (no change)

• Commissioning of GERB-1 (on MSG-2) completed.• GERB-1 exhibits an unstable period on leaving SAFE

mode that leads to a mispointing in NORMAL mode. The effect is self correcting after the mispointing event has occurred. This imposes a constraint on sun avoidance operations (in case of transition to safe mode).

• A data corruption anomaly is currently under investigation.• GERB-1 is in SAFE mode for the sun avoidance season.

GERB-2

• System ARB into the in-orbit detector damage – the final report has been issued in April 2007.

• Sun avoidance patch (patch 8) incompatibility with SNOOZE mode still under investigation.

GERB-3

• GERB-3 IEU has been returned to RAL for implementation of timing board modifications.

• The GERB-3 IOU QFM is to be repaired.

GERB-4

Detectors: • FM#3 detector damaged and is now to be replaced by FM#2.• Proposal for detector Humidity Test approved.• Proposal for recalibration of GERB-3 detector to be

considered.

Quartz Filter Mechanism (QFM): • Rebuild and re-integration indicate the problem has been

solved.
