1 1. SMOS Status 1.1 Payload 1.2 Platform 1.3 Satellite 1.4 Launcher 1.5 FOS 1.6 DPGS 2. Other Developments 3. Future (Near & Far) 4. Schedule 1

2 1.1 Payload General: Structural / Thermal Model test campaigns highly successful, no identified criticalities. Reduced Engineering Model used for (limited) functional / performance testing, communication with P/F, software validation. Still in use for e.g. X-band verification. Critical Design Review successfully passed. (Nov. 2005) PFM manufacturing / AIT in full swing 2

3 1.1 Payload Subsystem FM Development Status: All LICEFs, including the antenna and bandpass filters, have been delivered (incl. 3 spares and 6 LICEF for NIRs) NIRs are to be delivered this week Noise sources / power dividers / cabling for CAS delivery imminent First Command and Monitoring Node deliveries this week Pyro box, X-band antenna, filters (2), 1 transmitter (second one end May) MOHA units under final testing Command and Correlator Unit: merging of CCU / MOHA parts this week, environmental test programme (vibration, TV ) 3

5 1.1 Payload Antenna Pattern Measurements Antenna Measurement campaigns have been completed on the three arms A, B, C (different orientation of polarisation with respect to arm axis) with: STM hardware of arm elements and deployment mechanisms Flight LICEFs and antenna, incl. gaskets Representative thermal hardware for the grounding layer. Data processing is ongoing. Hub, with 3 inner segments of each arm, has completed dry run (to verify transportation, assembly, monitoring, measurement procedures) Actual Hub measurements schedule to commence 22 May! 5

8 1.1 Payload PFM AIT All structure, mechanisms, thermal control hardware, and harness available. LICEFs are transferred from STM elements RF and optical harness integration Harness and thermal control hardware integration CAS items (noise sources, splitters, RF harness) integrated as available CMNs, MOHA items as they become available Last: CCU, mid/end July electrical / functional testing 8

11 1.1 Payload PFM test campaign planning: Deployment test CASA) Electrical testing Mass properties Acoustic test Thermal balance / thermal vacuum EMC Image Validation Test The last test is the main performance test for the flight instrument. All tests at ESTEC facilities. Delivery of fully tested Payload PFM end 2006 to Alcatel Cannes. 11

12 1.2 Platform (from the PROTEUS Family!) Mind: Jason flying since 3 years Calypso just launched Corot under assembly for launch this year Jason 2 under assembly for launch mid 2008 Structure assembled Propulsion system integrated Most Electronic units integrated Present: progress interrupted, awaiting return of equipment and staff from Calypso launch campaign. First level P/L P/F communication tested with EM Second level P/L P/F communication test scheduled for Oct (with flight software loaded to P/L EM) 12

14 1.3 Satellite Merging of P/F and P/L to form the satellite to commence early Detailed test sequence is being established, taking account of SMOS-specifics (e.g. RF sensitivity, arm deployment, pyro verification) Nominal duration: 9 months (incl. realistic allocation for holiday periods, system verification, margin) 14

15 1.4 Launcher (Rockot) Joint launch with ESA s PROBA-2 satellite from Plesetzk (Rus) Preliminary Launcher Analysis Meeting concluded in March 2006: Injection strategy optimisation Platform safety issues S-band interference with MIRAS under the fairing i.e. no insurmountable problems. 15

16 1.5 Flight Operations Ground Segment Distributed between ESAC (Villafranca) and CNES (Toulouse) ESAC: Mission Planning, Payload Commanding (incl. payload simulator) S-band telemetry reception (from CNES) CNES: Satellite commanding (through S-band in Kiruna) Flight dynamics, S-band TM / TC Both developments progressing nominally. 16

17 1.6 Data Processing Ground Segment To be located at ESAC, the DPGS comprises X-band data reception antenna Level 0 processor (time sorting, attachment of anx/aux data, ) Level 1 operational processors Level 2 operational processors Core for managing processor jobs, local archive, despatch Quality control and monitoring facilities PDR successfully passed, but criticality remains mainly for the core the operational processors (debugging / validation against prototypes) overall system integration and test more details in N.Wright s presentation 17

20 2. Other Developments Level 1 Prototype Processor (Deimos Portugal under CASA): see presentations of M.Zundo / A.Guiterrez Level 2 Prototype Processors for SM and OS: see presentations of S.Delwart / ACRI / ARRAY Cal / Val AO: presentation by S.Delwart Campaigns: presentations by P.Wursteisen and participants 20

21 3. Future Developments (Near and Far) Political discussion ongoing about a Near Real Time Service for SMOS (i.e. products available within 3 hours from sensing). Probably only noise! Mid 2006, the AMIRAS should become available; initially for test flights, but then also for (focused) scientific campaigns Same for the HUT 2D interferometer: test flight expected shortly after return of HUT Skyvan from Cosmos OS campaign Technology preparation for an operational SMOS: after release of funds by PB-EO and CDTI, activity is supposed to start internally in June. 21

24 4. Schedule Generally, SMOS development schedule is on track. However, there are some risk elements to be watched: Delivery schedule for critical subsystems impact on start of PFM Test Campaign Possible conflicts for availability of test facilities GOCE, Herschel would get priority Impact of Corot Launch Resource conflicts with Jason 2 Long delay loop in Launcher iterations Criticality of Data Processing Ground Segment, in particular, processor development schedule. 24
