Soil Moisture and Ocean Salinity 1 SMOS IOCP Key-Point 0 09/12/ Operations Report of LEOP S. Burgaud / CNES

2 SMOS IOCP Key-Point 0 09/12/09 Ground Segment Status Orbitography Operational Centre : >involved for first orbit computation, until GPS switch ON >support for station acquisition manoeuvres, in case of problem  very good support supplied IT Network : >no major anomaly >ISDN line activated once because of nominal link maintenance activities Ground stations : >Good behaviour of the ground stations network >No issues on TTCET ground stations >Several minor anomalies with Homere stations : -TM file retrieval, RF link -no impact on SMOS operation planning -due to the fact SMOS is the first PROTEUS mission using these stations

3 SMOS IOCP Key-Point 0 09/12/09 Ground Segment status SOCC : –Very satisfying behaviour of all the components –No major anomalies –Main Change Requests implemented : >TC_Auto facilities : to allow automatic TC_Group upload during the night with Homère stations >E_HKTM files delivery : on ESA request, these files are now sent after each pass (instead of every 6 hours) >New Satellite data base : v 4.0 -Modification of ground monitoring relative to PLM temperatures -TC reject file correction,  To be set up by the end of the week Conclusion : CNES GS implied in SMOS LEOP worked like a charm, with very few harmless anomalies

4 SMOS IOCP Key-Point 0 09/12/09 Operational documentation for routine activities Smos In-Orbit Mission Management Plan : –Version 1.0 issued and signed by CNES and ESA Operation Interfaces Agreement between SOCC and PLPC –Issue 2.0 applicable + “E_HKTM delivery” Change Request –Weekly routine timeline is applicable from now, as defined –Collision avoidance process is activated –RF interferences with Jason 1 satellite are weekly computed, and avoided without impact on PLM planning PLPC-SOGS ICD : –Issue 1.9 applicable + “E_HKTM delivery” Change Request
