CEOS WGISS & Subgroup Meeting, Budapest, May CCSDS Structure

CEOS WGISS & Subgroup Meeting, Budapest, May 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

CEOS WGISS & Subgroup Meeting, Budapest, May 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)

CEOS WGISS & Subgroup Meeting, Budapest, May 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)

CEOS WGISS & Subgroup Meeting, Budapest, May 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

CEOS WGISS & Subgroup Meeting, Budapest, May 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

CEOS WGISS & Subgroup Meeting, Budapest, May 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

CEOS WGISS & Subgroup Meeting, Budapest, May 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.

CEOS WGISS & Subgroup Meeting, Budapest, May Recent General Issues o China invited to join CCSDS o Relationship between CCSDS and ECSS n ECSS: European o Issued new newsletter: CCSDS Link o for more CCSDS info
