CCSDS Overview

• The goal  For Space Data Systems, enhance
  interoperability and cross-support, while also
  reducing risk, development time and project
  costs, for government, industry, agencies,
  vendors and programs.
• Interoperability between agencies teams
  translates to operational flexibility, capability
  and access to additional resources
• CCSDS Started in 1982 developing at the lower
  layers of the protocol stack. The CCSDS scope
  has grown to cover standards throughout the ISO
  communications stack, plus other Data Systems
  areas (architecture, archive, security, XML
  exchange formats, etc.)

Some Organizational Interrelationships

• Typical IOAG communiqué to CCSDS

IOP Interoperability Plenary highest level
interagency agreements on space interoperability

• R 12.9.1 The IOAG requests the CCSDS
• to initiate the transition to an end-to-end
  networked communications architecture by
• developing a standard for CCSDS encapsulation
  service
• developing the DTN suite as standards
• developing a recommended practice for the
  deployment of the IP suite.

IOAG Interagency Operations Advisory Group
interoperable mission support infrastructure (Comm
Nav only)
CCSDS open international standards for space
mission interoperability
SFCG Space Frequency coordination Group space
agency spectrum management forum
Close Coordination for Internetworking
SISG
IOAG SISG Space Internet Strategy Group New
Intl agreements for Internetworking (ISO Layer
3) in Space

Some Organizational Interrelationships
OMG Object Management Group Industry standards
for exchange of application information among
vendor products CCSDS/OMG have some common
standards and periodic joint meetings
IETF Internet Engineering Task Force IRTF
Internet Research Task Force Open international
standards for IP suite and DTN CCSDS uses such
industry standards as a basis, whenever possible
ECSS European Consortium for Space Standards -
European regional standards for space mission
support CCSDS/ECSS coordinate on compatible
standards
AIAA American Institute of Aeronautics and
Astronautics North American regional standards
for space mission support Regional Standards
coordination, and AIAA provides Secretariat
support for CCSDS, ISO TC20/SC13 and SC14

Sampling of technical topics

• New Low-Density Parity Check codes
• LDPC codes provide better performance in space
  environment
• New codes specific to mission environments (Near
  Earth, Deep Space)
• Agencies currently downselecting from multiple
  options
• XML activities in many areas
• Data Archive, Registries, Repositories, etc.
• CCSDS XML Special Interest Group (SIG) working
  towards consistent approach across multiple
  standards
• Spacecraft Monitor and Control (SMC)
• One of the most active working groups,
  considering name change to Mission Operations
  WG because of current ground focus
• Service Oriented Architecture approach to
  application-level services
• Goals Interoperable monitor/control services,
  application portability between flight/ground or
  between partner agencies.
• New sub-areas starting Time services,
  automation services, planning/scheduling
  services, remote software management svcs.
• XML Telemetry and Command Exchange (XTCE) also in
  this area
• Worked jointly with OMG, getting broad acceptance

12
Sampling of Technical Topics (Cont.)

• Recently approved new work areas

CCSDS Summary

• Take-home message Still much work to be done
• Enabling interoperability between international
  agencies for future missions both Earth-Orbital
  and Exploration
• Long-range vision automated routing and delay
  tolerant networking for deep space crosslinks
  between spacecraft and surface systems
• Near-term need evolutionary approach to sustain
  cross-support agreements with other agencies.
• Organizations with a stake in the future of Space
  Operations and the expertise to contribute to
  CCSDS should become engaged.
