2
Outline.

• Motivation for using Distributed Simulation in
  ESA
• ESA programme on Distributed Simulation
• Co-operation with GCTC
• R D programme in Modelling Simulation
• Laboratory experiments
• Dissemination and promotion.
• Conclusions results and future activities.

3
Motivation for Using DS in ESA

• European Space projects are by nature distributed
• gt geographically distributed industry working in
  the same projects
• involvement of ESA, national agencies and
  industry
• gt a diversity of modelling and simulation
  environments
• Participation in international programmes with
  USA, Russia and Japan
• gt remote ground facilities need to be
  interconnected.

Motivation for Using DS in ESA (II)

• Interoperability of simulation platforms and
  ground facilities is essential to
• reduce duplication
• promote reuse
• achieve project goals.

6
ESA programme on DS.

• Cooperation with the Gagarin Cosmonaut Training
  Center (GCTC) on application of DS to spacecraft
  trajectory simulation and control.
• ESA RD programme in Modelling and Simulation
• application of HLA to simulation of a rendez-vous
  mission to the ISS.
• European space distributed simulation capability
• Laboratory HLA-based experiments
• Simulation of satellite payload operations.
• Dissemination of results
• DS workshops.
• On-going dialogue with industry
• Internet reflector, workshops and
  Hands-on-training (with the DMSO support).

7
Earlier experiences GCTC-ESA cooperation
Application to ISS operations (1278.1).

• From local to global simulations via
  interoperability
• Based the 1278.1 Standard
• GCTC-ESTEC RVD4 of ATV5 ISS simulation
  experiment
• Characteristics of Simulation scenario differ
  from the typical DIS scenario.
• Implementation of adapted Dead Reckoning
  Algorithm and special PDUs.

Application to Distributed User operation Centres

• Distributed Satellite Operations Simulator.
• Distributed Scenario
• Telemetry consoles
• Telecommand consoles
• Earth track 2D-Map
• connecting/disconnecting dynamically from the
  UK to the main simulation centre at ESA / ESTEC.
• Demonstrated life during DS-Workshop
  (ESTEC-04/98)

Conclusions.

• Potential of DIS/HLA to support space
  applications has been confirmed by preliminary
  experiments
• RD activities are on-going to confirm the
  feasibility of HLA to effectively support ISS
  operations.
• Planned RD activities will investigate HLA
  applications in engineering and the establishment
  of a low-cost European network.
• Interest of European industry is high
• Valuable support received from DMSO
• mechanism for raising space requirements on HLA
  is needed.
