8、ndation . 6 Bibliography . 7Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body intereste
9、d 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 collaborates closely with the International Electrotechnical Com
10、mission (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 Standards. Draft International Standards adopted by the techni
11、cal 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 this document may be the subject of patent rights. ISO sh
12、all not be held responsible for identifying any or all such patent rights. ISO 10784-3 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 14, Space systems and operations. ISO 10784 consists of the following parts, under the general title Space systems Early
13、operations: Part 1: Spacecraft initialization and commissioning Part 2: Initialization plan Part 3: Commissioning report ISO 10784-3:2011(E)iv ISO 2011 All rights reservedIntroduction The three parts of ISO 10784 provide spacecraft (SC) manufacturers and operators with a specific form and format for
14、 writing SC commissioning reports required to configure and verify the SC to perform normal mission operations. Often, SC manufacturers and operators have defined these reports uniquely for each programme, or regional, national and corporate organizations have unique commissioning reports. The three
15、 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 and comprehension of initialization and commissioning activities.

16、O 10784-3:2011(E) Space systems Early operations Part 3: Commissioning report 1 Scope A general definition of initialization is that it begins at separation of the spacecraft (SC) from the launcher. In some cases, a more exact definition will be that initialization begins in flight, upon planned cha
17、nge in mode or state of the SC from the launch configuration. Commissioning is completed when the SC, including its payload, is certified for initial mission operations. Prior to certification for mission operations, the SC is described as a test article in the three parts of ISO 10784. ISO 10784 do
18、es not include a requirement for contingency plans, but does include a statement of the need for contingency planning. This part of ISO 10784 outlines general descriptive information for SC initialization and commissioning as might be appropriate for programme management, project engineering or prog
19、ramme test documentation. Since the SC is considered a test article at this phase of its operational life, ISO 17566 is used as a normative reference in constructing the commissioning report. It provides SC manufacturers, SC operators and other stakeholders with a common language and form to verify
20、and document spacecraft initialization and commissioning prior to normal SC mission operations. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest e
21、dition of the referenced document (including any amendments) applies.
