9、s). 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. International organizations, governmental and n
10、on-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 rules given in the ISO/IEC Directives, Pa
11、rt 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 at least 75 % of the member bodies castin

The Committee meets periodical
19、ly 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 in themselves considered bind
20、ing on any Agency. CCSDS Recommendations take two forms: Recommended Standards that are prescriptive and are the formal vehicles by which CCSDS Agencies create the standards that specify how elements of their space mission support infrastructure shall operate and interoperate with others; and Recomm
21、ended Practices that are more descriptive in nature and are intended to provide general guidance about how to approach a particular problem associated with space mission support. This Recommended Practice is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommend
22、ed Practice is entirely voluntary and does not imply a commitment by any Agency or organization to implement its recommendations in a prescriptive sense. No later than three years from its date of issuance, this Recommended Practice will be reviewed by the CCSDS to determine whether it should: (1) r
23、emain 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 Practice is issued, existing CCSDS-related member Practices and implementations are not
24、 negated or deemed to be non-CCSDS compatible. It is the responsibility of each member to determine when such Practices or implementations are to be modified. Each member is, however, strongly encouraged to direct planning for its new Practices and implementations towards the later version of the Re
25、commended Practice.

43、the key to ensuring the correct functioning of various onboard systems and structures, the responses of these systems in their operational working environments, and the long-term reliability of the spacecraft. These data are also highly significant when compiling lessons learned that will be applied
44、 to building better space systems and increasing the reliability of future space components. (Refer to reference 3 for a comprehensive overview of application domains and for a detailed summary of RF communications and restrictions in differing operational environments.) The quantity of acquired spa
45、cecraft functional data depends on the ability to monitor required parameters at precise locations within a given project time and cost envelope. Hundreds and often thousands of data measurement locations are required, steadily increasing the mass (acquisition systems, cables, and harnesses) and the
46、 project costs and time (installation and verification of each new sensor). The use of wireless technologies is foreseen to reduce the integration effort, cost, and time typically required to instrument a high number of physical measurement points on a space structure. Technicians should need less t
47、ime to integrate and verify their installations, while the risk of mechanically damaging interfaces during the process should be reduced. Large structures should see health monitoring equipment mass reduced, while last-minute changes in the instrumentation (e.g., addition/removal of sensing nodes at
48、 measurement points) should be easier to accept at project level. One of the byproducts of using wireless technologies in space systems is the extra flexibility introduced when implementing wireless fault-tolerance and redundancy schemes. An overriding consideration in this document is the desire to
49、 provide recommendations that utilize wireless technology to augment the overall networking infrastructure in a spacecraft rather than to provide dedicated data transport to particular end-to-end application-specific subsystems. That is, although the recommendations specified in this document are related to relatively small-scale Personal Area Networks (PANs) rather the more familiar Local Area Networks (LANs) such as Ethernet, the desire is for w
