2 SMOS IOCP Key-Point 0 09 Dec ESAC SMOS Commissioning activities In the frame of the “In orbit Commissioning activities”, different milestones are planned in January 2010 : - Thales Platform Commissioning Key Point on 14 of January - Payload Key Point 1 on 20 of January - In orbit System Assessment Review on 20 and 21 of January The Platform Commissioning Keypoint : - Presentation made by Thales in Cannes of the detailed Platform in orbit commissioning results - This milestone will conclude formally the Thales development activities and will start the Thales In-flight MCO ( Operationnal Support Phase ) - As for previous SL development review’s, a summary of the Payload status would be appreciated : general behavior, PLM Health check results, Thermal, Bus IF …etc

3 SMOS IOCP Key-Point 0 09 Dec ESAC SMOS Commissioning activities In orbit System Assessment Review on 20 and 21 of January : - Presentations made by CNES and ESA in Toulouse will address the detailed In Orbit System Commissioning activities, with main objectives : MISSION ANALYSIS : Launch, Maneuvers ( sma, delta i ), Maneuver budget SATELLITE : Spacecraft (Bus and Payload) Assessment of functional behavior & performances ( Power AOCS Mechanical Thermal Command & control …), S band transceiver Link budget. GROUND SEGMENT : Satellite Operational ground segment status ( SOCC, PLPC, XBAS ), Network and interfaces, data transfers OPERATIONS : Ops feedback from LEOP & assessment phase, Satellite/Payload Data Base, ground surveillances, Operational process in routine DOCUMENTATION STATUS : Sequence plans, Operational CNES/ESA interface documents for routine (OIA, ICD…), On orbit management plan - This milestone will formally start the SL routine phase with the Hand Over from CNES development team to the CNES Operational team Payload Key Point 1 on 20 of January : - Proposal to converge on a joint agenda to merge the both KP and In orbit System Review objectives : a duration of 2 days meeting in Toulouse on 20 and 21 of January seems fully compatible to achieve objectives of the both meetings.

4 SMOS IOCP Key-Point 0 09 Dec ESAC SMOS Commissioning activities Miscellaneous : Operation during week 52/53 CNES will be closed from December 24th until January 3rd, as a consequence, a very restricted number of people will be allowed to enter in CNES facilities : only for emergency situation or safety reason. One single Proteus operation team on duty ( Mission/Space segment/Ground segment) Strategy proposed for Payload operation :  Last (.. for 2009) PLM TC group uploaded on December 23 at the latest  In case of red alarm on PLM, operational procedure applied with call of the Mission Operation Manager hot line  Only validated procedure to ensure safety of the PLM will be performed : up to switch off if necessary, no additional investigation nor PLM Switch on realized during the period Upload of SL TC (guidance) group in automatic mode on during this period
