SEA Area
OVERVIEW - SYSTEMS ENGINEERING AREA (SEA)
Welcome to the Systems Engineering Area (SEA) Collaborative Work
Environment.
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

SEA-SEC
OVERVIEW - SECURITY WORKING GROUP (SEA-SEC)
Welcome to the Security Working Group Collaborative Work
Environment. The Security Working Group (SEA-SEC) falls
under the Systems Engineering (SEA) Areas of the CCSDS.
CCSDS develops communications and mission operation
standards that support inter and intra agency operations
and cross support. CCSDS standards include elements of
flight and ground systems that are developed and
operated by different agencies and organizations.
Over the years, ubiquitous network connectivity among
principal investigators and mission operations has
become the norm, which makes mission operations more
dangerous than in the past when operations were carried
out over closed, mission-only networks. The security
risks to both spacecraft and ground systems have
increased to the point where CCSDS must adopt existing
or develop (as necessary) Information Security standards
in order to protect both flight and ground mission
critical resources and protect sensitive mission
information.
As a result, a mission threat statement for CCSDS should
be developed in order to allow mission planners to
better understand the threats that they should plan to
counter via security requirements. CCSDS also requires a
Security Architecture as part of its overall System
Architecture. CCSDS must promote secure interoperability
for space missions. CCSDS also requires Information
Security standards as part of, or as an accompaniment to
its communications and mission operations standards.

SEA-SANA
OVERVIEW - SANA WORKING GROUP (SEA-SANA)
Welcome to the SEA SANA WG Collaborative Work
Environment. The SEA SANA WG (SEA-SANA) falls under the
Systems Engineering (SEA) Areas of the CCSDS.
The core registrar for the CMC’s activities is the SANA.
Many space mission protocols require that someone keep
track of key protocol numbering assignments that were
added after the protocol came out. Typical examples of
the kinds of registries needed are for Spacecraft IDs,
protocol version numbers, reserved APIDs and SFDU
Control Authorities. The SANA provides this key
configuration management service for CCSDS. The CMC
approves the organization that will act as the SANA. Its
public interface is focused through web-based services
provided by the Secretariat.
At present the SANA exists only as a concept. There are
many different data objects that need to be globally
accessible within the CCSDS in order to support mission
planning and operations and the activities of CCSDS
itself. A “Data Object”, within this context, is defined
as any known or imagined participant in mission
communications, planning, and operations or trajectory
propagation, tracking, attitude determination and orbit
determination.

SEA-D-DOR
OVERVIEW - DELTA-DOR WORKING GROUP (SEA-D-DOR)
Welcome to the Delta-DOR Working Group Collaborative Work
Environment. The Delta-DOR Working Group (SEA-D-DOR) falls
under the Systems Engineering (SEA) Areas of the CCSDS.
This working group is intended to provide a forum for developing
an integrated approach for delta differential one way ranging
(D-DOR) end to end services.
- Develop detailed requirements for delta differential one-way
ranging (Delta-DOR) service
- Coordinate work in other WGs (SIS/Ranging, CSS/CSTS, MOIMS/Nav)
- Develop integrated vision of service and interoperability
points
- Develop any over-arching documents, as needed
