SMOS LEOP Summary M. Venet
LEOP summary • Negative chronology : As planned. Launch occurred 02/11@01:50:51 • Injection orbit : OK • Sma : less than 1 km above ICD req • Inclination : 98,451° (ICD : 98, 445°) • Payload deployment : Nov 3rd. OK • Nominal attitude acquisition : Nov 6th. OK • Final orbit acquisition : reference orbit given to ESAC Nov 21th after : • One sma/delta e correction : Nov 12th • One inclination correction : Nov 16th • One trim manoeuvre : Nov 19th. • 700g hydrazine burnt vs 5500g planned! • Next OCM not earlier than March 2010 • Mean Local Time stability within 5 years : 30 sec from reference • Payload switch on : Nov 17th and 18th. OK • Overall system behaviour during LEOP : satisfactory
Satellite/System assesment • Achieved tasks • STR2/Gyro3 destocking : Nov 20th and 23th. OK • SADM control laws assessment : Nov 24th and 25th. OK • Calibration manoeuvre assessment : Nov 30th to Dec 3rd. OK • Inertial 2’, 30’ • Zenithal 110’ • PLPC IF : OK • E_HKTM delivery rhythm modified • Minor exchanges issues on PLTM • Remaining tasks • STR1 additional expertise requested by Thales : to be replanned (1 orbit) • RF masking computation assessment : to compare G2 computation vs actual : transparent to PLM activity • Sband signature, SA movements interference & STR shielding verification (part of Payload commissioning) : to be replanned • Satellite, SOGS & Team are ready for Payload Commissioning activity : In Orbit assessment review foreseen January 21 in CNES
