Outline

• Scope of this domain
• Objectives of RD in this domain
• Relevant technologies required
• Major RD activities envisaged
• Current activities.

4
Scope

• Covers the technologies that support the
  effective cooperation of distributed teams in
  carrying out the technical tasks (e.g. design and
  verification) within a project. It covers the
  following areas
• Remote access to data, applications and
  facilities
• Shared applications, tele-(video)-conferencing
• Distributed interactive simulation
• Advance Distance Learning.

5
Objectives

• Since most of the basic technology exists,
  the RD strategy here is to facilitate access to
  this technology by means of
• Enhancing existing applications to cope with a
  distributed operation
• Developing middle-ware software
• Gathering experience in the use of this
  technology
• Developing guidelines for configuration of
  computer and communication equipment

6
Relevant Technology

• Web technology
• Shared applications and tele-(video)-conferencing
  technology (e.g. Netmeeting)
• Distributed interactive simulation (e.g. DIS/HLA)
• Distributed databases / Distributed Product Data
  Management
• (High) speed networks and associated middleware
  (e.g. GRID)

Distributed Interactive simulation
8
Distributted Interactive simulation

• Standard Technology (IEEE 1516).
• Tested in ESA projects since 1994
• Simulation of chaser/target vehicles (95)
• Focused on distributed interactive simulation
  (96)
• First ever application of DIS Std. in space (97)
• First ever application of HLA Std. in space (98)
• Distributed Interactive Simulation for Rendezvous
  Mission (DIS-RVM, with EADS (former Aerospatiale)
  and D3)
• Distributed User centres for Earth Observing
  Small Satellites (Headway)
• Remote Operation of Rendezvous Sensor Test
  Facility (EPOS, DLR)
• ESA NASA demonstration in 2001
• ESA NASA NASDA (demonstration in June 2003)
