The CMC approves the organization that will act as the SANA. Its public interface is focused through web-based services provided by the Secretariat. The SANA is the CCSDS operational core registrar for the CMC’s activities. The day-to-day operation of the SANA is conducted by the SANA Operator as defined in the SANA Procedures Yellow Book, CCSDS 313.0-Y-0.3. Technical oversight of the activities of the SANA Operator are delegated to the SANA Steering Group (SSG).
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.
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.

The CCSDS Secretariat edits, formats, and publishes CCSDS Recommendations (in their various stages of maturity) and provides one definitive repository for all CCSDS documentation. The Secretariat also assists in scheduling and supporting all CCSDS meetings.
An important role of the Secretariat is to support the CMC process of formal Agency review. The vehicle for such review is the ‘Review Item Disposition’ or ‘RID’. When a document requires formal review, the Secretariat will announce the review opportunity to the CCSDS Agencies and will provide instructions that define how, when, and to whom the Agency comments (in the form of completed RIDs) are to be submitted.
The Secretariat provided a wide range of Web-based information services in support of the technical development work of CCSDS. These include archived mailing lists, document manipulation and sharing services, document libraries, electronic balloting facilities and a system to log and distribute Concept Papers that are derived early in the development process. The Secretariat shall also provide Web-based information services that cater to the two-way flow of information between CCSDS and its customers and industrial suppliers.

The Data Compression Working Group (SLS-MHDC) falls under the Space Link Services (SLS) Areas of the CCSDS.
On-board data compression is needed to make full use of limited spacecraft resources like data storage and downlink capacity. Multispectral & hyperspectral images can occupy enormous data volumes, and so compression algorithms specifically designed to exploit the three-dimensional structure of such images can provide tremendous benefit to space missions.
The Multispectral & Hyperspectral Data Compression working group has developed the CCSDS-123.0-B-1 standard, a state-of-the-art low-complexity lossless compressor.
The working group is now working on extending the CCSDS-122.0-B-1 (two-dimensional) image compressor by adding a spectral transform stage to provide multispectral and hyperspectral (three-dimensional) image compression.

The Space Link Coding & Synchronization Working Group (SLS-C&S) falls under the Space Link Services (SLS) Areas of the CCSDS.
Agencies’ new generations of space missions require telecommand and telemetry capabilities beyond current technologies to interconnect a spacecraft with its ground support system, or with another spacecraft. These new needs are for higher data rates, better link performances, together with lower cost, mass and power and higher security.
The wide range of environment (space-Earth or space-space, near Earth congested bands and deep space link operations in extreme conditions of SNR, links dependent of atmospheric conditions in the new high frequency bands, optical links) requires coding systems with different levels of power efficiency and bandwidth efficiency, or different levels of link reliability or delivered data quality;
This work will concentrate on updating the existing set of Channel Coding Blue Books to incorporate recommended coding scheme for new bandwidth efficient codes with low complexity. The update work includes also the extraction of the coding layer out of CCSDS 211.0-B Prox-1 Protocol.

The Service Management Working Group (CSS-SM) falls under the Cross Support Services (CSS) Area of the CCSDS
The use of Space Link Extension services require the exchange of information that will allow a space flight mission to acquire those services from SLE service providers. The current ad hoc mechanisms for arranging, scheduling, control, and monitoring of SLE services are fragile and manually intensive. Production of the currently-specified suite of SLE services is coupled to the underlying radio frequency, modulation, coding, and link characteristics. There are no current standards for arranging, scheduling, control, and monitoring of TT&C services. The potential user base for a service management standard for arranging, scheduling, control, and monitoring of SLE and TT&C services is larger than the space Agencies that constitute the CCSDS membership.

Delay Tolerant Networking Working Group (SIS-DTN) falls under the Space Internetworking Services (SIS) Areas of the CCSDS.
The Delay Tolerant Networking Working Group is specifying the protocols needed to implement the Solar System Internetwork (SSI) concept. These protocols support the portion of the SIS communication domain where large delays, intermittent connectivity, and/or unidirectional communications links may be present.
The main internetworking protocol in the Solar System Internet is the Bundle Protocol (BP). BP is a message-oriented store-and-forward communication protocol with optional reliability that is suitable for use when contemporaneous end-to-end connectivity cannot be guaranteed. BP routers may store data (bundles) before forwarding them, possibly for long periods of time. This allows routers to forward data even if the outbound communication link is not available when the data arrives. The Bundle Protocol and all the supporting protocols in the SSI suite are designed for these conditions. This is in contrast to many of the protocols in the Internet Protocol (IP) suite that at least implicitly assume low delays and end-to-end connectivity. The working group is specifying a profile of the Bundle Protocol as specified in Internet RFC5050 for use by CCSDS.
BP has been demonstrated in a number of experiments both on the ground and with spacecraft, including the Deep-Space Networking Experiment (DINET), the Earth-Observing Mission-1 (EO-1) spacecraft, and various single- and multi-agency experiments on the International Space Station (ISS).
In addition to the Bundle Protocol, the working group is specifying a profile of the Licklider Transmission Protocol (LTP, RFC5326) for use in CCSDS missions, as well as network management and security protocols.
The group works with and leverages work done in the terrestrial DTN community, including the Internet Research Task Force’s DTN Research Group (http://www.dtnrg.org).

The Applications Support Services Working Group (SOIS-APP) falls under the Spacecraft Onboard Interface Services (SOIS) Areas of the CCSDS.
The Applications Support Services Working Group defines standard services that are provided to onboard software applications. These services isolate the flight software from the underlying hardware details and thereby increase the portability and reuse potential of the flight software. Furthermore, the service access points constitute cross support interfaces.
The standard services that are addressed by this working group are those that have been identified during previous CCSDS SOIF activities as being common requirements in all spacecraft missions, and providing the maximum benefit for flight software development. Furthermore, it is explicitly recognized that interoperability and cross support capabilities need to be provided throughout the project lifecycle, and particularly during application development, integration, and testing, not just during operations.

The Data Archive Interoperability Working Group (MOIMS-DAI) falls under the Mission Operations and Information Management Services (MOIMS) Areas of the CCSDS.
Agencies need to reduce the cost and increase the automation associated with acquiring and ingesting data and metadata to archives. Archives, including both mission and final, need appropriate metadata to accompany data objects to facilitate long term preservation. Currently submission requirements are usually totally ad hoc by mission, or by a given multi-mission archive or final archive. Producers of information for archives often seek guidance on how to submit such information. The OAIS reference model and the Producer-Archive Interface Methodology Abstract Standard set a context for all archives. Further, registries are of increasing importance as the holders of re-usable metadata in the exchange of information. This work will establish an extensible framework for a Submission Information Package (SIP). It will include mandatory and optional elements, with the ability to recognize categories of information and relationships.

The Spacecraft Monitor and Control Working Group (MOIMS-SC) falls under the Mission Operations and Information Management Services (MOIMS) Areas of the CCSDS.
There is a general trend toward increasing mission complexity at the same time as increasing pressure to reduce the cost of mission operations, both in terms of initial deployment and recurrent expenditure. Current closed, or monolithic¹, mission operations system architectures do not allow the re-distribution of functionality between space and ground, or between nodes of the ground system. The SM&C WG is defining a service oriented architecture consisting of set of standard services, which constitutes a framework that enables many similar systems to be assembled from compliant plug-in¹ components. These components may be located anywhere, provided they are connected via a common infrastructure. This allows components to be re-used in different mission-specific deployments: between agencies, between missions, and between systems. By layering the services themselves, the service specifications can be made independent of the underlying technology and the application coding language. Specific technology adapters enable the deployment of the service framework over a given technology. This in turn makes it possible to replace the infrastructure implementation as well as component implementations. It is also possible to transparently bridge between different infrastructure implementations, where these are appropriate to different communications environments (e.g., space or ground) or simply reflect different agencies deployment choices.

The objective of the Space Internetworking Services (SIS) Area is to address the communications services and protocols supporting end-to-end communications among applications, particularly where those communications may span multiple heterogeneous physical and data link technologies. Areas addressed by SIS include the networking infrastructure to support application-to-application communication onboard a single spacecraft, communications among multiple spacecraft, and communications between space-based applications and their counterparts on Earth and/or other planetary bodies.
The SIS Area deals with communication services and protocols that are independent of specific link technology (as a lower layer bound) and independent of application-specific semantics (as an upper bound). Thus the SIS area covers essentially the network through application layers of the OSI reference model.
SIS protocols use the underlying communication and infrastructure services provided by the Space Link Services (SLS) and Spacecraft Onboard Interface Services (SOIS) areas and any other onboard networks, and provide the networked connectivity needed by applications developed in other CCSDS areas such as Mission Operations and Information Management Services (MOIMS) and Spacecraft Onboard Interface Services (SOIS). The SIS services provide hardware-independent mechanisms for identifying end systems, and provide communications services that allow users to disregard whether the communication is over a single data link layer or over multiple hops. The suite of capabilities developed by the SIS Area accommodates all ranges of delay, interactivity, and directionality, although not all protocols are appropriate for all environments.
The services provided by SIS protocols free applications from having to have intimate knowledge of the underlying communications protocols and mechanisms, and from having to know the physical location(s) of the entities with which they are communicating. This enables applications to focus on the application-specific protocols and interactions necessary to achieve their goals.

A space link interconnects a spacecraft with its ground support system or with another spacecraft. Agencies’ new generations of space missions require telecommand and telemetry capabilities beyond current technologies. These new needs are for higher data rates, better link performances, more performing ranging systems, together with lower cost, mass and power and higher security.
More specifically, SLS area 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). Two additional functions are also covered by the SLS area : data compression for end to end data transfer optimization, and ranging for accurate orbit determination.
The area is composed of specialized working group whose objective is to develop specific recommendations. One recommendation will typically cover one OSI layer or sub-layer. This layering of recommendations maximizes flexibility and interoperability with other commercial protocols (e.g. : TCP/IP).

The Cross Support Services (CSS) Area addresses how space network resources are made available by one organization to another for the purpose of “Cross Support”. The objective of the CSS Area is therefore to define what services are required at various cross-support interface points, and how those services are exposed, scheduled and used by organizations that want to confederate their infrastructure in order to execute a mission.

The objective of the Mission Operations and Information Management Services (MOIMS) Area is to address all of the flight execution phase applications that are required to operate the spacecraft and its ground system in response to mission objectives, and their associated detailed information management standards and processes. The focus of this Area is primarily on the “mission operations” functions that occur on a timescale driven by the flight path of the space vehicle. In many cases a dedicated community conducts these mission operations, while “mission utilization” occurs on a timescale that is convenient for users and is often conducted by a separate community. The MOIMS Area ensures that application standards exist which facilitate the smooth transition of space mission information between the “mission operations” systems and the “mission utilization” systems.

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.

The Systems Architecture Working Group (SEA-SA) falls under the Systems Engineering (SEA) Areas of the CCSDS.
The work done in the other Working Groups is focused upon services and protocols provided by specific components of space data systems. In order for these Working Groups to generate standards in such a way that every standard is consistent and coherent with any other standard generated by CCSDS, CCSDS requires a reference architecture that can be used as a common framework by all the Working Groups of CCSDS and also by engineers in the member Agencies who use CCSDS standards to build systems and to provide services. The reference architecture should encompass both informatics and telematics aspects of space data systems and cover all problem areas associated with space data systems (such as organizational, functional, operational and cross support issues).
POINTS OF CONTACT
Chair: Shelbun Cheng
Deputy Chair: Paul ThompsonThe System Engineering Area (SEA) supports the work of the CCSDS by providing :

The CCSDS Engineering Steering Group (CESG) provides technical management across the various CCSDS Areas and ensures top-level technical coordination of the overall international standardization process. It ensures that all developments occur in accordance with procedures, schedules, and resources that have been negotiated with the CMC. To do its job the CESG adopts and applies uniform architectural views that guide the systems protocols, policies and procedures used for international space mission cross support. The CESG is directly responsible for executing the actions associated with entry into and movement along the CCSDS standardization tracks, including making recommendations to the CMC for approval of specifications as they progress through the various stages of standardization.

The CCSDS Management Council (CMC) is the executive management oversight group of the organization. The CMC is populated by Principal Delegates who are independently supported by each of the Members (one per agency). The CMC is responsible for staying technically and politically informed about important long-term issues in the field of international space mission cross support and for keeping an eye on the “big picture” of the CCSDS program of work. It therefore focuses on long-range planning and coordination among the various CCSDS discipline-oriented domains, on making sure that adequate resources exist to do work, and that customer requirements are satisfied in a timely manner.
