Concurrent Development Environment

• CODE IMPLEMENTATION
• Satellite Power Budget scenario
• Multiple Platforms PC-Windows, HP-UX, SGI-IRIX
• Interoperate with
• Attitude Control simulator
• Thermal models (ESATAN, ESARAD)
• Avionics Database
• Operations Database
• Adopted in real cases
• GOCE satellite (ESA)
• Herschel-Planck satellite (ESA)

6
Distributed Collaborative Engineering

• Study objectives
• Identify current practice of collaborative
  engineering in space projects
• Define the reference scenarios for the
  application of
• distributed systems applications
• Re-use and capitalise available results and
  Alenia Spazio expertise
• Evaluate new available solutions and commercial
  tools
• Consolidate a common approach for future
  dissemination
• Minimise the risk of under- or over- estimate
  the future needs
• Follow the reference ECSS standards

7
Space Engineering needs

• New Concurrent Simulation paradigms
• Multidisciplines
• Different actors, geographically distributed
• Models data consistency
• Near-real-time response
• Provide quick response to configuration updates
• Computing resources on request
