The Purpose of ESA

• ESA is an intergovernmental organisation with a mission to provide and promote, for exclusively peaceful purposes:

– Space science, research and technology– Space applications

• ESA achieves this through:– space activities and programmes– long-term space policy– a specific industrial policy– coordinating European national space programmes

Page 4


• ESA has 17 Member States

• Austria, Belgium, Denmark, Finland, France, Germany, Greece,Ireland, Italy, Luxembourg,Norway, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom

• Canada takes part in some projects under a cooperation agreement

Page 5


The ESA Programmes

• All Member States participate in activities and a common set of programmes related to space science (mandatory programmes)

• In addition, members choose their level of participation in the following optional programmes:

– Manned spaceflight

– Microgravity research

– Earth observation

– Telecommunications

– Navigation

– Launcher Development

• Mission Operations Information System (MOIS)

•Tool for operations procedures development and maintenace

• Editing, configuration control, traceability, document production

• I/F to satellite database (SCOS)

• Based on WINFOPS (Windows Flight Operations Procedures System) – COTS (Microsoft Office) procedure generation tool

• Easy to use, familiarity, configurable (1-2 mm per mission)

• All current ESA (except Integral) and future missions based on MOIS

• Automation of sytem using PLUTO scripts

• Typical sizing: ENVISAT 1700 procedures

ROSETTA 700 procedures

Engineering Tools - Operations Preparation

SCOS-2000 – Spacecraft Control Operations System supports all functions needed to acquire, process, display and archive TM and to send and archive TCs:

• Runs on UNIX Platforms (SUN/Solaris or PC/LINUX)

• Modern layered architecture

• Supports packet TM and TC CCSDS standards and ESA PUS standard

• Highly scalable (from single WS or PC – ‚SCOS-2000 in a box‘, to complex configuration with over tens of WS)

• Multi-mission support (constellations) – architecture design

- Studies eg. Related to Galileosat)

• Satellite check-out eg. Herschel-Planck

- Satellite level

- Instrument (P.I.) level

Engineering Tools - SCOS-2000

Software Infrastructure for Modelling SATellites (SIMSAT)

• Dec/alpha VMS version currently used – phased out

• PC/Windows-NT version (current baseline)

• Move towards LINUX/PC version (2005-2006)

Generic models

• Customisable and re-usable

• Currently available models include: position and environment, 1750 processor emulation, ERC32 emulation (all missions from Cryosat), power distribution, OBDH protocol, packet TM encoding and TC decoding, ground station equipment

• Will be upgraded to support new simulator model portability standards in the near future

• Future: 64-bit Intel processor emulation
