PICARD : Consortium meeting 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 DAVOS, 29 -30 November 2010 group GETCU (JP Marcovici) 3

PICARD : Consortium meeting OPERATING MODES SODISM : ETH mode Decontamination, Nominal Scientific mode : Nominal mode, Night Mode, Distortion, Stellar PREMOS : Science and Night mode SOVAP : A 02, A 03, A 04, A 09, A 14 R 04, R 05, R 06, R 10 MUX 0, MUX 5 SYNCHRONIZATION : SODISM SOVAP Each day SODISM PREMOS : Twice per orbit for 215 nm and 607 nm with HEAD B Channel 1 and 2 DAVOS, 29 -30 November 2010 group GETCU (JP Marcovici) 4

PICARD : Consortium meeting CHANGE OF CONFIGURATION SODISM : change thermal configuration Date Temp CCD 31/7/2010 -18°C 4/9/2010 -10°C 3/8/2010 -13°C 21/9/2010 -9. 25°C PREMOS : change thermal configuration Date Temp CCD 26/7/2010 TH 1=24°C TH 2=23°C 13/9/2010 TH 1=26°C TH 2=25°C 6/9/2010 TH 1=26°C TH 2=26°C SOVAP : mode used on board A 02, A 03, A 04, A 09, A 14 R 04, R 05, R 06, R 10 MUX 0, MUX 5 DAVOS, 29 -30 November 2010 group GETCU (JP Marcovici) 5

PICARD : Consortium meeting 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 DAVOS, 29 -30 November 2010 group GETCU (JP Marcovici) 6

Meissonnier (revue of end of Commissioning period) Erreur de pas Go and back to RAZ position +1 -1 +2 -2 +3 -3 Roue 1 5960 1536 1510 27 39 0 1 Roue 2 7368 753 752 0 0 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 DAVOS, 29 -30 November 2010 group GETCU (JP Marcovici) 9

PICARD : Consortium meeting 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 1) SOVAP: it become necessary to prevent all telecommand that close 2)the right shutter 2) SOVAP : This requirement can becomes obsolete if need 3) SODISM : Necessity to have full images compressed by Langevin with filters helio 4)Point 1 and 3 will be treated thanks to a new version of the software 5)(planning max February 2011) 6)Point 2 will be treated by a patch of the memory (very easy processes) DAVOS, 29 -30 November 2010 group GETCU (JP Marcovici) 10
