The work of preparing International Standards is normally carried out
10、 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 non-governmental, in liaison with ISO, also take part in the work. ISO col
11、laborates 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, Part 2.The main task of technical committees is to prepare International Sta
12、ndards. 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 casting a vote.Attention is drawn to the possibility that some of the elements of
13、 this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 10784-2 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 14, Space systems and operations.ISO 10784 consists of the follo
14、wing parts, under the general title Space systems Early operations: Part 1: Spacecraft initialization and commissioning Part 2: Initialization plan Part 3: Commissioning reportISO 10784-2:2011(E)iv ISO 2011 All rights reservedBS ISO 10784-2:2011IntroductionThe three parts of ISO 10784 provide spacec
15、raft (SC) manufacturers and operators with a specific form and format for writing SC initialization plans and commissioning reports required to configure and verify the SC to perform normal mission operations. Often, SC manufacturers and operators have defined these plans and reports uniquely for ea
16、ch programme, or regional, national and corporate organizations have unique initialization plans and commissioning reports. The three parts of ISO 10784 aim at establishing a common language and form for SC stakeholders. The use of one form and format will simplify stakeholder understanding of initi
17、alization and commissioning activities.ISO 10784-2:2011(E) ISO 2011 All rights reserved vBS ISO 10784-2:2011BS ISO 10784-2:2011INTERNATIONAL STANDARD ISO 10784-2:2011(E)Space systems Early operations Part 2:Initialization plan1 ScopeA general definition of initialization is that it begins at separat
18、ion of the spacecraft (SC) from the launcher. In some cases, a more exact definition will be that initialization begins in flight, upon planned change in mode or state of the SC from the launch configuration. Commissioning is completed when the SC, including its payload, is certified for initial mis
19、sion operations. Prior to certification for mission operations, the SC is described as a test article in the three parts of ISO 10784. ISO 10784 does not include a requirement for contingency plans, but does include a statement of the need for contingency planning.This part of ISO 10784 provides SC
20、manufacturers and operators with a specific form and format to write spacecraft initialization plans required to configure and verify the SC to perform normal mission operations. Since the SC is considered a test article at this phase of its operational life, ISO 17566 is used as a normative referen
21、ce in constructing the initialization plan. It provides SC manufacturers, operators and other stakeholders with a common language and form to verify and document spacecraft initialization prior to normal SC mission operations.2 Normative referencesThe following referenced documents are indispensable

25、tion plan4.1 Introduction clause of the initialization plan4.1.1 GeneralThe introduction clause is a preliminary element which shall be used to give general information or commentary about the technical content of the initialization plan and about the reasons prompting its preparation. Because the s
26、pacecraft is not yet certified for operations, it is described as a test article. The introduction shall include a brief description of initialization and its objectives. It shall not contain requirements.4.1.2 ObjectiveThe objective subclause shall specify the desired initialization outcome in term
27、s of SC certification, acceptance or other development. The objective may reference other clauses or subclauses which appear later in the document.4.1.3 ScopeThe scope subclause shall define, without ambiguity, the SC, the range of testing covered by the plan and the applicability of the plan in rel
28、ation to fulfilling SC initialization objectives.The initialization plan document shall provide input information for the generation of overall commissioning objectives. The initialization plan document may be a part of the overall spacecraft programme test plan.4.1.4 BackgroundThe background subcla
29、use is optional. If included, it may discuss the background of the spacecraft programme if that information benefits the overall understanding of the initialization plan.4.2 Referenced documentation4.2.1 GeneralThis clause shall provide a list of the documents to which reference is made in the initi
30、alization plan.Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained.4.2.2 Normative referencesNormative references are published standards and specifications that provide requirements or constraints for initialization.
