Consultative Committee for Space Data Systems

From Wikipedia, the free encyclopedia

The Consultative Committee for Space Data Systems (CCSDS) was formed in 1982 by the major space agencies of the world to provide a forum for discussion of common problems in the development and operation of space data systems. It is currently composed of ten member agencies, twenty-two observer agencies, and over 100 industrial associates.

Since its establishment, it has been actively developing Recommended Standards for data- and information-systems standards to

1. reduce the cost to the various agencies of performing common data functions by eliminating unjustified project-unique design and development, and
2. promote interoperability and cross support among cooperating space agencies to reduce operations costs by sharing facilities.

[edit] Recommendations

The CCSDS develops recommendations, called Blue Books, for standards in order to:

• Reduce the cost of performing space missions
• Enable cross support for space missions
• Improve understanding of space related data
• Preserve archived space related data

[edit] Benefits of CCSDS

• Promotes Understanding of Exchanged Data

• Reduces Nonrecurring Costs:
  • Fewer Project-Specific Developments
  • Shorter Test Times
  • Less Training of Staff is Needed

• Reduces Recurring Costs:
  • More Commercial Off-the-Shelf COTS Hardware is Needed
  • Fewer Facilities Because of Load Leveling
  • Only Selected Redundancy is Needed
  • More Automation, Less Staff

• Mitigates Mission Risk
• Enables Ingest and Access Data Archives

[edit] Important CCSDS Standards

• Telemetry Channel Coding
• Packet Telemetry
• Space Link Extension Services (SLE)
• Space Communications Protocol Specifications (SCPS)
  • SCPS-FP
  • SCPS-TP
  • SCPS-SP
  • SCPS-NP
• Proximity-1 Space Link Protocol
