  1. Herschel Satellite Acceptance test campaign Instruments consolidation scenario

  2. Agenda • 14:00 1- Introduction & Objectives • 14:05 2- Herschel S/C Acceptance campaign flow • 14:20 3- Project Team Organisation • 14:35 4- Instrument Test Matrix • 15:20 5- Constraints to Instrument Test • 16:00 6- Current S/C Schedule and Test Flow • 16:15 7- Instrument verification status at S/C level • 16:45 8- AOB • 17:30 9- Agreements and MoM signature

  3. Introduction & Objectives • Herschel Integrated Team & Instrument Teams fully aligned for the Satellite acceptance tests: • Consolidation of instrument verification at satellite level • Objectives, environment, boundary conditions, organisation • procedure/scripts to be prepared/delivered by instrument teams • how to coordinate instrument involvement at satellite level tests • Better understanding of the situation / schedule evolvements, • Ways to improve the preparation and execution coordination, • Instruments interface cooperation and relationship,

  4. Herschel S/C Acceptance Campaign Flow 1/2 IST1 & SVT1 in He I I&T,UFT & SFT in Warm Conditions IST1 in Warm Conditions Cryostat Evacuation & Cool-down Cryostat Cool-Down & HSS/Telescope integration He II Production & Top-up TV/TB in He II EMC R in He II SOVT1 in He II IST1 & SPT1 in He II Mechanical in He I IST2 & SPT2 in He II FAR He II -> He I conversion He II Production & Top-up

  5. Herschel S/C Acceptance Campaign Flow 2/2 FAR Process SOVT2 in He II SVT2 in He I Leak check, Packing & departure to KRU He II -> He I conversion End of acceptance activities S/C AFT & Preparation for launch in He I He II Production & Top-up Hydrazine filling in He I Combined operations Launch Campaign

  6. Industrial Project Team Organisation 1/2

  7. Industrial Project Team Organisation 2/2 • Herschel Integrated team, technical main points of contacts • Schedule = Denis Montet • Engineering = Bernard Collaudin • Product Assurance = Andy Knight • Verification = Test Directors (see organigramme) • AIT = Test Conductors (see organigramme)

  9. ESA Project Team Organisation 2/2 • Herschel ESA team, technical main points of contacts • AIV = Flemming Pedersen • Schedule = Flemming Pedersen • S/C Product Assurance = Ulrich Gageur • Instruments Engineering = Carsten Scharmberg • Cryostat = Chris Jewell • Instruments Product Assurance = Ian Rautakoski

  10. Instruments Test Specification • H-P-2-ASP-TS-1083_2.0 - Herschel Instruments FM IST Test specification • Specification established in collaboration between Industry/ESA and instruments teams, to specify instruments tests to be performed on Satellite level, and to remain the reference for these tests. • Double goal: • To instruments teams : To specify/explain which instruments test will be performed at satellite level (Objectives, environment, boundary conditions, organisation), and consequently which procedure/scripts instruments have to prepare • To specify to S/C AIT : Specify which instrument test will be performed (configuration, environment, duration, sequence …), and how or organize it. • Covers UFT, SFT, IST/commissioning, IST/RMS, SPT, TV, + define instruments state during EMS and S/C IST. • Collects & manage Instruments test procedures. Central site on ftp: • ftp://ftp.hp-instruments.as-b2b.com/industry_to_instruments/Herschel FM Integration & tests • Has been built from an overall test table elaborated with instruments (now updated from available procedures: last one = Herschel instruments FM IST_2007-11-26.xls) • Issue 1 published in Sept 06. Comments received from this date have been incorporated in issue 2 draft • In agreement with ESA, Issue 2draft 3 released (Industry/ESA/Instruments) for comments. Ready for signature • Today, comments on this issue 2 draft 3received from SPIRE & ASED. Distributed as an excel database (= detailed change log: Change notice - H-P-2-ASP-TS-1083 - Instrument IST spec.xls)
