2-2 Operations Report of LEOPS. Burgaud / CNES

2SMOS 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

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
