RECOMMENDATION FOR SPACE DATA SYSTEMS STANDARDS CCSDS GLOBAL SPACECRAFT IDENTIFICATION FIELD: CODE ASSIGNMENT CONTROL PROCEDURES CCSDS 320.0-B-2 BLUE BOOK October 1998 AUTHORITY Issue: Blue Book, Issue 2 Date: November 1998 Location: Darmstadt, Germany This document has been approved for publication by the Management Council of the Consultative Committee for Space Data Systems (CCSDS) and represents the consensus technical agreement of the participating CCSDS Member Agencies. The procedure for review and authorization of CCSDS Recommendations is detailed in reference [1], and the record of Agency participation in the authorization of this document can be obtained from the CCSDS Secretariat at the address below. This Recommendation is published and maintained by: CCSDS Secretariat Program Integration Division (Code MG) National Aeronautics and Space Administration Washington, DC 20546, USA STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of member space Agencies. The Committee meets periodically to address data systems problems that are common to all participants, and to formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed RECOMMENDATIONS and are not considered binding on any Agency. This RECOMMENDATION is issued by, and represents the consensus of, the CCSDS Plenary body. Agency endorsement of this RECOMMENDATION is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever an Agency establishes a CCSDS-related STANDARD, this STANDARD will be in accord with the relevant RECOMMENDATION. Establishing such a STANDARD does not preclude other provisions which an Agency may develop. o Whenever an Agency establishes a CCSDS-related STANDARD, the Agency will provide other CCSDS member Agencies with the following information: - The STANDARD itself. - The anticipated date of initial operational capability. - The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neither this RECOMMENDATION nor any ensuing STANDARD is a substitute for a memorandum of agreement. No later than five years from its date of issuance, this Recommendation will be reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or (3) be retired or canceled In those instances when a new version of a RECOMMENDATION is issued, existing CCSDS-related Agency standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each Agency to determine when such standards or implementations are to be modified. Each Agency is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommendation. FOREWORD This document is a procedural Recommendation which establishes control procedures for Spacecraft Identification (SCID) codes. As such, it defines the procedure governing assignment, use, relinquishment, and management of SCIDs. To make the most efficient use of the available identification (ID) space in the several CCSDS-recommended data structures that contain a SCID field, all CCSDS-compatible missions will be assigned SCIDs by a single central authority, the World Data Center A for Rockets and Satellites (WDC-A-R&S), located at the Goddard Space Flight Center in Greenbelt, Maryland, USA. As specified in this Recommendation, WDC-A-R&S will accept only requests from designated Agency Representatives and only when received on approved Request Forms. This Recommendation also provides: - a list of the CCSDS Agencies' Representatives as of the date of this document; - a form for requesting and relinquishing SCIDs. Through the process of normal evolution, it is expected that expansion, deletion or modification to this Recommendation may occur. This Recommendation is therefore subject to CCSDS document management and change control procedures which are defined in Reference [1]. Current versions of CCSDS documents are maintained at the CCSDS Web site: http://www.ccsds.org/ccsds/ Questions relating to the contents or status of this Recommendation should be addressed to the CCSDS Secretariat at the address on page i.

As such it addresses the requesting, assigning, using, relinquishing, and managing of SCIDs. The purpose of the CCSDS SCID is to serve as a mechanism for the identification of: - a simple spacecraft having only one logical space-ground link; or - an association between space-based and ground-based application processes with complex spacecraft having more than one logical space-ground link. Therefore, a single spacecraft may be assigned more that one SCID. This identification may be used only throughout a spacecraft's active phases, e.g., simulations, prelaunch testing, and in-orbit operations. As quickly as practical after reception of telemetry data, the SCID should be replaced with a globally unique, unambiguous, permanent, and SCID-independent label for the spacecraft and/or payload data set(s). Thereafter, access to and identification of these data sets shall be by means of this label rather than the SCID field described in this document. These procedures are intended to eliminate the possibility that data from any given CCSDS-compatible vehicle will be falsely interpreted as being from another CCSDS-compatible vehicle during the periods of simulation, testing, or mission operations. Since the data structure (synchronization code and virtual channel data unit/transfer frame/telecommand frame) are common to many missions, misinterpretation of the identity of space vehicle or ground-based simulator assemblies is possible unless procedures are developed and followed to identify uniquely each vehicle or assembly during its active phases. Because the SCID field is only eight or ten bits long for virtual channel data units and transfer frames respectively, the SCID is not intended to provide unique identification for all times. It is inevitable that the SCIDs will have to be reused; however, at any one time, the number of vehicles under simulation, test, or active operational control is not anticipated to exceed the available numbering domains. As used throughout this document, the term SCID shall be construed to be limited in scope to the CCSDS-defined data fields. Other non-CCSDS-compatible data structures may also use this term; however, this document does not apply to the assignment and use of identification codes for non-CCSDS-compatible data structures. In such cases the potential for misinterpretation is negligible because of differences in the overall data structures. 1.2 BACKGROUND SCID codes appear in many of the CCSDS-recommended data structures used for the space-ground links and other purposes. Typical of the space-ground data structures that incorporate the SCID are: - the Conventional Mission Telemetry Frame (Reference [3]); - the Conventional Mission Telecommand Transfer Frame (Reference [2]); - the Advanced Orbiting Systems Virtual Channel Data Unit (Reference [4]). Inasmuch as there are numerous technical and administrative considerations attendant to SCID management and control, i.e., requesting, assigning, using, and relinquishing SCIDs, this document hereby establishes procedures and guidance for SCID management and control. 1.3 GLOBAL SPACECRAFT IDENTIFIER (GSCID) The GSCID is defined to be the concatenation of the 2-bit Version Number (VN) and the Spacecraft Identifier (SCID). Thus, GSCID = VN . SCID Where "." refers to the concatenation operator. The valid range of the currently defined VN field is shown in Table 1. Table 1: Bit Structure of Currently Defined VN Fields Version Binary Encoded VN Range of SCID No. of Bits in SCID Encoded Relevant CCSDS Documents 1 00 0-1,023 10 Ref. [2] & [3] 2 01 0-255 8 Ref. [4] NOTE - The binary encoded VN values of "10" and "11" are reserved for possible future use and should not be used for project-unique purposes prior to formal agreement within CCSDS for such use. The CCSDS Recommendations on telemetry and telecommand protocols (references [2], [3], and [4]) provide a mechanism for establishing an ASSOCIATION (either temporary or permanent) between space-based application process(es) and corresponding ground-based application process(es). The data streams transmitted between space and ground processes will contain IDENTIFIERS which will specify the relevant association. These identifiers are MANAGED parameters (i.e., the specific association implied by a given identifier must have been previously established). The utilization of the SCID field on a global scale necessitates its concatenation with other fields in the References and, therefore, the name Global SCID or GSCID. 1.4 APPLICABILITY This Recommendation applies to all spacecraft that are compatible with CCSDS protocols contained in those documents listed in the References section of this Recommendation. 2 SCID CODE ASSIGNMENT CONTROL PROCEDURES 2.1 CCSDS SCID MANAGEMENT SYSTEM DUTIES AND RESPONSIBILITIES CCSDS SCID assignment and management, on an international basis, must be viewed as a cooperative effort among the CCSDS Agencies, with each constituent acting as agent for the users under its cognizance. The management system comprises four elements: 2.1.1 CCSDS Secretariat shall 2.1.1 - serve as the focal point for the resolution of any issues not adequately covered by these procedures; - request that CCSDS Member Agencies appoint, maintain, and replace as necessary an official Agency Representative (AR) to handle all SCID requests from that Agency. 2.1.2 CCSDS Head of Delegation shall - provide the CCSDS Secretariat and the WDC-A-R&S with the name and address of the person authorized to be the Agency Representative (AR) as needed to keep this information current. NOTE - A list of ARs as of the date of this Recommendation is included as Annex A. 2.1.3 Agency Representative (AR) shall - submit SCID requests in accordance with the provisions of this Recommendation; - interact directly with WDC-A-R&S with regard to any issues relating to a specific SCID assignment request; - monitor the life of those CCSDS missions within his/her Agency and relinquish all SCIDs at the earliest practical time, which shall not in any event be longer than two months after receipt of the last expected telemetry signal; - inform the applicable Agency personnel of any relevant actions (i.e., SCID assignment, relinquishment) taken by WDC-A-R&S relating to that Agency. 2.1.4 World Data Center A for Rockets and Satellites (WDC-A-R&S) shall - serve as the assignment manager; - accept, from authorized ARs, requests for SCID assignments; - review and log SCID assignment requests; - assign one or more SCIDs in response to the request and notify the appropriate AR of the assignment(s); - interact directly with the appropriate AR in matters dealing with a particular SCID assignment request; - maintain complete and independent catalogs of SCID assignments for each version number and periodically provide the catalog of currently assigned SCIDs to the CCSDS Secretariat, CCSDS Heads of Delegation, and Member/Observing Agency ARs; - work with the respective ARs to recover all SCIDs, corresponding to those spacecraft whose operational phases have been completed, for subsequent reassignment. 2.2 SCID ASSIGNMENT REQUEST PROCEDURES 2.2.1 All SCID Assignment Requests by an Agency shall be submitted by the designated AR. 2.2.2 All SCID Assignment Requests shall be submitted on the approved request form as contained in Annex B. 2.2.3 A separate form shall be used for each SCID requested. 2.2.4 All SCID Assignment Requests are to be submitted in writing to: World Data Center A for Rockets and Satellites Code 633.2 NASA Goddard Space Flight Center Greenbelt, MD 20771 United States of America TELEPHONE: +1 301 286 6695 FAX: +1 301 286 1771 EMAIL: request@nssdca.gsfc.nasa.gov NOTE - Telephone communications can be used only to request information. They cannot be used to request SCIDs. 2.3 SCID CODE ASSIGNMENT PROCEDURES 2.3.1 All CCSDS SCID Assignments shall be made by the WDC-A-R&S. 2.3.2 Each SCID Code Assignment shall be globally unique during its assignment period. 2.3.3 SCID Code Assignments will be made on a spacecraft-by-spacecraft basis. User requests for reservation of a sequence of ID numbers for unspecified spacecraft will not be accepted. However, multiple SCIDs may be assigned for those missions which have multiple spacecraft or which require separate designations for protoflight spacecraft or simulations. 2.3.4 User requests for assignment of specific numerical codes will be accepted. However, the user should refer to the catalog of existing SCID assignments (see 2.1.4) to avoid requesting assignments that could result in duplication, and, therefore, denial of a request. 2.3.5 The SCIDs that are relinquished by an Agency will not be immediately reassigned. Rather, the relinquished SCIDs will be placed at the bottom of the stack of unassigned SCIDs, thereby maximizing the period of time before the relinquished number is reassigned. 2.4 SCID RELINQUISHING PROCEDURES 2.4.1 The AR shall determine, in conjunction with the mission manager, exactly when the operational phase of a mission is complete and when the related SCIDs can be relinquished. 2.4.2 The AR will submit to WDC-A-R&S a copy of the original Assignment Request/ Relinquishment form with the section entitled, "RELINQUISHMENT AUTHORIZATION" completed and signed. If the original Assignment Request/Relinquishment form cannot be located, a simple letter relinquishing the SCID will be acceptable. 2.4.3 WDC-A-R&S will place that SCID code number at the bottom of the stack of SCIDs available for assignment.
