  1. PLATFORM STATUS I PMOD/WRC Davos 29-30 november 2010 Présenté par : JP. MarcoviciSigle : LATMOS

  2. SOMMAIRE • STATUS OF PGCU AND FLIGHT SOFTWARE • OPERATING MODE • CHANGE OF CONFIGURATION • FLOW SODISM SCIENCE TM • SOME PRELIMINARY REPORT FOR SODISM • UPDATE OF THE OPERATIONNEL FLIGHT SOFWARE

  3. STATUS OF PGCU AND FLIGHT SOFTWRE • Load a new operational flight software after launch with dump of the flash and verification by dowload of the code • status : OK • Communications PGCU SODISM SOVAP PREMOS status : OK • No error detected • Patch operation (28/9/2010) status : OK

  4. OPERATING MODES SODISM : ETH mode Decontamination, Nominal Scientific mode : Nominal mode, Night Mode, Distortion, Stellar PREMOS : Science and Night mode SOVAP : A02, A03, A04,A09, A14R04, R05, R06, R10 MUX0, MUX5 SYNCHRONIZATION : SODISM SOVAP Each day SODISM PREMOS : Twice per orbit for 215nm and 607nm with HEAD B Channel 1 and 2

  5. CHANGE OF CONFIGURATION SODISM : change thermal configuration PREMOS : change thermal configuration SOVAP : mode used on board A02, A03, A04,A09, A14 R04, R05, R06, R10 MUX0, MUX5

  6. FLOW SODISM SCIENCE TM They are two compression on board Lossless compression (PLLC) With degradation (Langevin) The compression rate of PLLC depend of the noise on the pixels of CCD So the commissioning period allow to define the size of limb PLTM and macro-pixels The perspective is to allow about 51 pixels of large for the diameter measurements

  7. REPORT ABOUT SODISM SHUTTERS (Electronic point of view)

  8. REPORT ABOUT SODISM SHUTTERS (Electronic point of view)

  9. SODISM Filter wheels from 01/08 to 30/09 Extract from a slide of M. Meissonnier (revue of end of Commissioning period) The requirement To have to steps or less of difference is respected Pm : 2 steps correspond to 0.2 mm to 0.5 mm of movement on the filter

  10. UPDATE OF THE OPERATIONNEL FLIGHT SOFWARE • When they are new requirements on the payload, the only possibility is to try to treat them, with the operational software • 2 problems now • SOVAP: it become necessary to prevent all telecommand that close • the right shutter • SOVAP : This requirement can becomes obsolete if need • SODISM : Necessity to have full images compressed by Langevin with filters helio • Point 1 and 3 will be treated thanks to a new version of the software • (planning max February 2011) • Point 2 will be treated by a patch of the memory (very easy processes)
