System Engineering Area

The System Engineering Area (SEA) supports the work of the CCSDS by providing:
  • Overall architecture for space mission communications, operations, and cross-support.
  • Coordination and collaboration with the other areas about architectural choices and options.
  • Supporting the CESG in evaluating consistency of all area programs of work with the defined architecture.
  • Creating such working groups and BoFs as are required to progress the work of CCSDS.
