8、ional standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Interna
9、tional organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the r
10、ules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by a
11、t least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 20208 was prepared by the Consultative Committe
12、e for Space Data Systems (CCSDS) (as CCSDS 506.1-B-1, June 2013) and was adopted (without modifications except those stated in clause 2 of this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information transfer systems.

17、W DATA EXCHANGE FORMAT CCSDS 506.1-B-1 Page ii June 2013 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of its members. The Committee meets periodically to address data systems problems that are common to all
18、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 Recommended Standards and are not considered binding on any Agency. This Recommended Standard is issued by, and repr
19、esents the consensus of, the CCSDS members. Endorsement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever a member establishes a CCSDS-related standard, this standard will be in accord with the relevant Recommended Standard. Establ
20、ishing such a standard does not preclude other provisions which a member may develop. o Whenever a member establishes a CCSDS-related standard, that member will provide other CCSDS members with the following information: - The standard itself. - The anticipated date of initial operational capability
21、. - The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neither this Recommended Standard nor any ensuing standard is a substitute for a memorandum of agreement. No later than three years from its date of issuance, this Recommend
22、ed Standard 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 Recommended Standard
23、 is issued, existing CCSDS-related member standards and implementations are not negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such standards or implementations are to be modified. Each member is, however, strongly encouraged to direct plannin
24、g for its new standards and implementations towards the later version of the Recommended Standard.

25、ndard for Delta-DOR Raw Data Exchange Format and has been prepared by the Consultative Committee for Space Data Systems (CCSDS). It has been developed via consensus of the Delta-DOR Working Group of the CCSDS Systems Engineering (SEA) area. The Delta-DOR Raw Data Exchange Format described in this Re
26、commended Standard is the baseline concept for Delta-DOR data interchange applications that are cross-supported between Agencies of the CCSDS. This Recommended Standard establishes a common framework and provides a common basis for the format of Delta-DOR data exchange between space agencies. It all
27、ows implementing organizations within each Agency to proceed coherently with the development of compatible derived standards for ground systems that are within their cognizance. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CCSD
28、S shall not be held responsible for identifying any or all such patent rights. Through the process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control
29、procedures, which are defined in Organization and Processes for the Consultative Committee for Space Data Systems (CCSDS A02.1-Y-3).

38、one of the following subsection headings: Overview; Background; Rationale; Discussion. 1.3.2 UNIT NOTATION The following conventions for unit notations apply throughout this Recommended Standard. Insofar as possible, an effort has been made to use units that are part of the International System of U
39、nits (SI Units); units are either SI base units, SI derived units, or units outside the SI that are accepted for use with the SI (see reference 2), e.g., Hz: Hertz s: second 1.3.3 BIT AND BYTE ORDERING In this document, the following convention is used to identify each bit in an 8-bit byte. The firs
40、t bit in the byte (i.e., the most right justified when drawing figures and tables) is defined to be Bit 1, the following bit is defined to be Bit 2, and so on up to Bit 8.

41、 506.1-B-1 Page 1-3 June 2013 Byte ordering follows the convention of starting with Byte 1 (i.e., the most right justified when drawing figures and tables) and increasing to the left. 1.4 COMMON DELTA-DOR TERMINOLOGY Part of the standardization process involves the agreement on common interagency te
42、rminology and definitions that apply to interagency Delta-DOR. The following conventions apply throughout this Recommended Standard: baseline: The vector joining two tracking stations. channel: A slice of the frequency spectrum containing a spacecraft or quasar signal. raw data: Time-ordered samples
43、 of received radio signal voltage. sample: Instantaneous measurement of a radio frequency signal voltage. scan: An observation of a radio source, with typical duration of a few minutes. session: The time period of the Delta-DOR measurement including several scans. meteo data: meteorological data (co
44、nsisting of pressure, temperature, and relative humidity). 1.5 STRUCTURE OF THE DOCUMENT Section 2 provides a general overview of the Delta-DOR technique and introduces the need of the raw data exchange. Section 3 describes the basic structure and contents of the CCSDS-recommended RDEF for Delta-DOR
45、. Section 4 provides a description of the RDEF observation file. Section 5 provides details on the RDEF product file. Section 6 describes the RDEF file naming conventions. Annex A lists the parameters for which conventions need to be specified. Annex B discusses security aspects for the RDEF. Annex
46、C is a list of abbreviations and acronyms applicable to the document. Annex D provides a list of informative references. Annex E provides an example of a RDEF Observation File.
