Preamble
Many things to learn for the new SGS manager– New field– Long history– Not written
Trying to drive a project – in a public & research organization– With industrial constraints– With moving deadlines
Trying to «stick to field reality» :– Quality management being lighten– Risk management is very sensitive
Presentation is build by L. Vibert & JL Puget talk is given by JL Puget

We need to improve management efficiency
Items under configuration– List and content have to be updated
• items under the project configuration control limited to ICDs, test plans involving other SGS elements (MOC, LFI, PSO)
• Development and tests of items involving only HFI should stay within HFI configuration control
– Critical s/w which have been extensively tested and used should go to a light reporting (for ex RTA, QLA, TA/SP), “nice to have” improvements are out of SGS1
Already working with modified constraints– merge documents to make their update easier and thus the
documentation more effective to use for the internal HFI management Planck project organization
– Activate a steering group at management level (MOC,PSO,LFI,HFI SGS)
– Improve definition of responsibilities of different groups like ICWG/PGSSG, multiplication of meetings and questions, too many people, mixing of the internal instrument operations with legitimate organisation of interfaces
Quality process and risk management reassessment– Goal: define what’s helpful, avoid useless overheads

Risks status
Reminder :– Risks was managed through an open list on www.planck.fr as a
way to indentify risks– Risks assessment was mainly technical– No escalation of them really happened– The previous ones are mostly outdated
Risks have been reassessed in Dec 06 by the management following the way it was done on the instrument
Most were technical and closed, L1 schedule risk was worked on, checked to be on time
Main HFI-SGS project risk raised : IDIS/ ProC component delivery
L. Vibert, J.L. Puget
ProC risk and mitigation plan
(status at 15th of January 2007)
At the project level, the risk is seen as :– ProC has difficulties running in HFI environment– Critical features might not be delivered in time to test the FM
pipeline before the GS Readiness Review (beginning 08)
Mitigation– Weekly technical MPA-HFI telecon (no IDIS, LFI is invited)
• Detail requirements of the ProC functions to be implemented
• define the validation, integration acceptance procedure
• Direct discussions of bugs & features requests between engineers
– In March 07 and at the May IDIS management meeting: key point for assessment of confidence of the required ProC delivery in time
– In parallel define temporary alternative plan.
L. Vibert, J.L. Puget
Planning difficulties in the last year
Planning is supposed to be a driving tool but :
Manpower has been constrained by « emergencies » and delays in the instrument schedule:
– support to Instruments integration, tests, problems with acquisition chain (all solved today)
– Support to users (calibration phase, data to broadcast, analyse and maintain) (finished)
– Support to instrument team for system tests (still on going)
A number of small items are emerging as the project is progressing :– Evolution of IDIS/DMC– Modification of Instrument Model– Tackling the data exchange internaly (IAS, IAP, USPDC, Cambridge) and
externally with LFI– …
Main milestones drifting with launch date:– Lack of availability of interfaces– GS readiness review drifting
HFI milestones well identified, detailed planning not yet rebuilt

Procedures status
367 differents TeleCommands
For the HFI and HFI/sat tests, we’ve written:– 72 elementary procedures (1 to 15 TCs)– 18 types of configuration files– numerous macro-procedures for E2E tests, ISTs, cryo tests @CSL
For the operations with MOC we have to rewrite them (mainly because of incompatible SCOS versions between Alcatel and MOC) !– Already done : SVT0 on AVM (=1st FOP : from HFI power on to
bolometers setup and observation & optimisation modes)– To be done : FOPs, CPV procedures, contingencies– To be done : specific procedure to be able to update the data
compression factors during one DTCP (because of very tight TM rate)
This rewriting of procedures is a severe risk for the whole GS

L1 software versions Version V1 was developed for HFI calibration (CQM, FM Sc.
Characterization and then calibration) – Fully tested total of the order of 4 months of operation; used to degug all
problems with DPU interface– interfaced with DMC V1 (PIOLIB) – Includes the acquisition of data from calibration equipment (Saturne tank,
calibration set up)– Could be used if needed for flight
Version V2 developed for flight – Remove all calibration related modules, rewrite modules which were source of
instabilities – Includes two modes
• a “batch mode” ingest in the DMC the consolidated data received everyday (large chunk of data)
• A “near real time mode” ingest data in the DMC by smaller chunk of data for near real time access to the data (calibration, ground system tests, CPV phase)
– HFI L1 want to ingest all HK-TM from LFI, Sorption cooler, Spacecraft to be able to follow directly critical parameters (all thermometers, on/off flags for elements of the SC and PL, …)
• HFI has done that on specific HK during CSL-FM1 tests (all Sorption cooler HK, Temperatures on the LFI mock up which allowed us to determine the transfer function of temperature fluctuations through the whole Planck cryo chain
• this is not flight critical,• L1 team will work on that after the final testing of the critical elements and delivery to
MOC (end June 07) and the CSL FM2 tests end of 2007 to be available for these tests– see next slides for implementation verification validation status

L. Vibert, J.L. Puget
SGS other Interfaces 1/2
Timeline exchange, Maps and Power Spectra exchange (HFI-LFI-PSO)– File (FITS ) exchange in specific repository– Automatic FTP retrieve (HPFTS)

L. Vibert, J.L. Puget
Next SGS1 implementation steps
Already tackled :
Integration of HFI-DMC V2 Use non-HFI telemetries Definition workflow of data, SGS system view
– Which data ? Which rate ?– Between institutes, between instruments
Work on Instrument procedures (FOP, Contingencies) IMO evolution (see FXD’s talk) Data archive and maintenance philosophy for next years
(including calibration and test data)
L. Vibert, J.L. Puget
Overall Summary
SGS1 status is in line with the Review objectives Some system aspects of operations needs to be
consolidated Manpower:
– team was understaffed especially during period of delayed calibration and system integration (still on going)
– During this period management was also sub-critical– 3 additional s/w engineer since SGS DR– CITA team extends its contribution to operation tools and
operations (after completing QLA)
Instrument related activities of the SGS1 team start to decrease
Completion of SGS1 development will be ready in time for SOVT1 and finished for CSL FM2
