2. CEOS WGISS Meeting, Hanoi May 2007. 2 CCSDS Structure

3. CEOS WGISS Meeting, Hanoi May 2007. 3 ISO TCs o ISO TC20 Aircraft and Space Vehicles o Sub-Committee-13 (SC13 (CCSDS)) n Space Data and Information Transfer Systems o Sub-Committee-14 (SC-14) n Space Systems and Operations o Debate about have a new TC for Space n Merger has not been agreed

4. CEOS WGISS Meeting, Hanoi May 2007. 4 SYSTEMS ENGINEERING AREA (SEA) o Area Director, Peter Shames (NASA JPL) o the System Engineering Area (SEA) is responsible for describing the overall architecture for space mission communications, operations, and cross-support. n System Architecture WG n Information Architecture WG n Security WG n Space Assigned Numbers Authority (SANA) BoF n Space Ground Interoperability Architecture (SGIA) BoF n Special Interest Group (SIG) that has just started to develop XML Standards & Guidelines (XSG). o Working on: n The Reference Architecture for Space Data Systems (RASDS) n Reference Architecture for Space Information Management (RASIM)

5. CEOS WGISS Meeting, Hanoi May 2007. 5 MISSION OPERATIONS AND INFORMATION MANAGEMENT SERVICES AREA (MOIMS) o Area Director, Nestor Peccia (ESA) o The MOIMS Area includes all of the flight execution phase applications required to operate the spacecraft mission and its ground system in response to mission objectives, and associated detailed information management standards and processes. n Data Archive Ingestion (DAI) - follow-up to OAIS n Navigation (NAV) n Information Packaging & Registries (IPR) – includes XFDU n Spacecraft Monitor & Control (SM&C) n SAFE format for archiving being worked on in this Area

6. CEOS WGISS Meeting, Hanoi May 2007. 6 CROSS SUPPORT SERVICES AREA (CSS) o Area Director, Gerard Lapaian (CNES) o The CSS Area concerns the extension of the space link on the ground between the ground station and the Mission Data Operation Service. o Working on n Service Mangement Specifications n Data Transfer Service Toolkit

7. CEOS WGISS Meeting, Hanoi May 2007. 7 SPACECRAFT ONBOARD INTERFACE SERVICES AREA (SOIS) o Area Director, Patrick Plancke (ESA/ESTEC) o the SOIS Area objective is to radically improve on- board data systems design and development process by defining generic services that will simplify the way flight software interacts with flight hardware. n Time Critical Onboard Applications Services (TCOAS) WG n Time Critical Onboard Networking (TCONS) WG n Onboard Bus and LAN (OBL) WG n Plug and Play BoF n Wireless S/C Interfaces BoF

8. CEOS WGISS Meeting, Hanoi May 2007. 8 SPACE LINK SERVICES AREA (SLS) o Area Director, Jean-Luc Gerner (ESA/ESTEC) o The SLS Area is responsible for developing efficient space link communications. It concentrates on layers 1 & 2 (of OSI protocol stack), namely: RF & modulation, channel coding and data link layer, for both long-haul (e.g.: spacecraft to ground) and proximity links (e.g.: orbiter to lander). o Also covers: data compression for end to end data transfer optimization, and ranging for accurate orbit determination. o Several Working Groups

9. CEOS WGISS Meeting, Hanoi May 2007. 9 SPACE INTERNETWORKING SERVICES AREA (SIS) o Area Director, Robert Durst (MITRE) o The SIS Area provides services and protocols to address networked interactions of many forms: between spacecraft and earth-based resources; among spacecraft; between spacecraft and landed elements; and within heterogeneous spacecraft. n Cislunar Space Internetworking (CSI) WG n Asynchronous Messaging Services (AMS) WG n CFDP Interoperability Testing WG n IP-over-CCSDS BoF.

10. CEOS WGISS Meeting, Hanoi May 2007. 10 Recent General Issues o ESA’s SAFE Format being proposed for long- term digital archive of ESA data. o http://www.ccsds.org/ for more CCSDS info http://www.ccsds.org/
