(ECSS = European Co-operation for Space Standardisation)

STEP for Aerospace Applications at NASA/GSFC

why need a wg and standard exchange of product data
Why need a WG and standard “Exchange of Product Data” ?
  • Efficient and effective electronic exchange of product data is considered a key enabler forfaster/better/cheaper development of space products
  • Long term, tool-independent archiving of product data is also needed in many space programmes
  • European space community (industry and agencies) need a frame of reference in order to standardise on protocols for the communication of product data

STEP for Aerospace Applications at NASA/GSFC

brief background of the wg
Brief background of the WG
  • 1994: ESA started developing STEP-based data exchange standards (in co-operation with CNES)
    • At first focusing on thermal analysis model exchange
  • 1994 to 1998: interest broadened across disciplines
    • Electronic product definition, concurrent engineering, etc.
    • Growing maturity of STEP / more capable CAx tools
  • May-98: first informal meeting industry and agencies to assess need, support, Draft Terms of Reference for a WG
  • Feb-99: Officially installed as ECSS WG E-10-07

STEP for Aerospace Applications at NASA/GSFC

tasks of the wg
Tasks of the WG
  • Review of existing international product data exchange standards and their suitability for use in space projects - focusing primarily on STEP
  • Identification of areas for which adapting / developing space-specific STEP-based standards is cost-effective - recommendation and promotion of further actions
  • Production of an ECSS standard for the exchange and archiving of product data in space projects
    • Including guidelines concerning the implementation / use of the standard

standardisation approach 1
Standardisation approach (1)
  • ECSS E-10-07 is part of E-10 “System Engineering”
  • Addresses exchange via neutral standards (1) between different tools of one discipline(2) between tools of different disciplines
  • Archiving is considered an application of (1)

STEP for Aerospace Applications at NASA/GSFC

standardisation approach 2
Standardisation approach (2)
  • Targeted disciplines:
    • ECSS-M-40 - Configuration Management
    • ECSS-M-50 - Information / Documentation Management
    • ECSS-M-70 - Integrated Logistic Support
    • ECSS-Q-70 - Material, Mechanical Parts & Processes
    • ECSS-E-10 - System Engineering
    • ECSS-E-20 - Electrical & Electronics
    • ECSS-E-30 - Mechanical (including thermal)
    • ECSS-E-40 - Software Engineering (only on CI level)
    • ECSS-E-60 - Control Systems
    • ECSS-E-70 - Ground Systems & Operations

standardisation approach 3
Standardisation approach (3)
  • E-10-07 is an ‘umbrella’ standard
    • Specifies which standard to use for what PDE situation
    • Makes reference to existing international standards
    • Primary focus on ISO 10303 (STEP)
    • Adds guidelines / best practices on how to use the standard
    • Designed for tailoring by individual projects
    • Only file-based exchange in scope for first release

STEP for Aerospace Applications at NASA/GSFC

standardisation approach 4
Standardisation approach (4)
  • Identified candidate STEP(-based) standards
    • AP 202: Associative draughting
    • AP 203: Configuration controlled design
    • AP 209: Composite and metallic structural analysis and related design
    • AP 210: Electronic assembly, interconnect and packaging design
    • AP 212: Electrotechnical design and installation
    • AP 214: Core data for automotive mechanical design processes
    • AP 232: Technical data packaging core information and exchange
    • AP 233: Systems engineering application protocol
    • STEP-TAS AP: Thermal Analysis for Space (ESA)
    • STEP-NRF AP: Network-model Results Format (ESA)
    • STEP-PRP AP: Propulsion Systems (CNES)

requirement for tailoring
Requirement for tailoring
  • It is very unlikely that in practice such a standard can be applied as a whole to a project
  • It shall be possible to use the standard as a contractual document in a programme or projectby declaring a subset of applicable clausesto specify the data exchange protocolsthat shall be used between parties
  • Requirement for tailoring is recognised across all ECSS standards

STEP for Aerospace Applications at NASA/GSFC

ecss e 10 07 initial core requirements specification
ECSS E-10-07Initial core requirements specification
  • A extensive list of structured 4-element requirements:
    • “To exchange datafrom a <source_discipline> representation
    • to a <destination_discipline> representation
    • for the purpose of transferring <kind_of_data>
    • the <exchange_standard> standard shall be used.”
  • For long term archiving the requirement as for exchange within one discipline shall be used
    • Identical <source_discipline> and <destination_discipline>

status schedule of wg
Status/schedule of WG
  • 17 members (1/3 from agencies, 2/3 from industry)
  • 3 working meetings held
  • Terms of reference written and agreed
  • First working draft produced
    • Currently in review and comment loop
    • Proofs difficult to actively involve industry in production of the standard (as always with long term benefits)
  • Goal is first release of standard early 2000
