PASO is: ë A TRANSVERSE organization within CNES Toulouse, in charge of preliminary studies and phases 0 with: An office with full time engineers ( 5 to 10 pers) l A nominative group of 60 “affiliate” part time agents from different specialized services (Technical, thematical, operation, costing, . . ) l PASO was created on end 2001, this organization ensures - the sharing and focusing of necessary human resources and competences (that cannot be dedicated to the “future”) - homogeneous study skills and reports (helping rational projects choices) - the development of means/tools (Concurrent Engineering) PASO was confirmed “as is” within the new matrix like CNES Toulouse organization in 2003. 2

PASO Study Process ë Paso study plan is established on annual base and revised periodically (study subjects issued from programmatic needs and CNES internal Call for ideas) ë Studies are divided into 3 phases separated by Key point l l l PH 01 ( 1 To 6 months duration) : -> To Identify the points that drive the mission needs, those that drive the technical difficulty and the costs, those that drive the future programmatic (brick reuse, cooperation) and to map them into a set of scenarios PH 02 (2 to 3 months)-> To optimize, refine, Compare the scenarios (cost, performance, criticality) PH 03 (2 to 3 months) -> Full Pre-Sizing of the preferred Scenario. Optional, only if necessary for a correct assessment of Criticality /performance/Cost NOTA: - Concurrent Engineering ( CDF) is used in PH 03 and sometimes in PH 02 - The 3 phases cannot be fully sequential (need of some back and forward ) ë The Study report contents: l l Mission requirement for Phase A entrance Reference technical solution/architecture Study limits and sensitivity factors Links with R/T programme (use of technologies being developed and/or new needs) 6

Links with R/T ë PASO and R/T -> 2 complementary processes for preparing the future in CNES l R/T -> To master the bricks (technology, . . ) for future missions l PASO -> To design future missions with good trade-offs between needs, costs, and risks. ë A PASO study must well identify the “bricks” that back the mission design and trade-offs and that needs R/T effort. ë A R/T action can need first a PASO study to identify the success conditions of a new technology ( perf. , interfaces, cost) ë A PASO study is short (3 to 12 months), R/T actions can last several years. ë The TRL (Technology Readiness Level) and « roadmap » approaches consolidate the R/T- PASO link 10
