11、, Sun Nov 26 14:36:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI iv Foreword 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 technica
12、l 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 collaborates closely wit
13、h 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 Standards. Draft Inter
14、national 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 this document may
15、 be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14711 was prepared by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 14, Space systems and operations. BS ISO 14711:2003 Licensed Copy: sheffieldun shef
16、fieldun, na, Sun Nov 26 14:36:28 GMT+00:00 2006, Uncontrolled Copy, (c) BSI v Introduction This International Standard defines the steps required to develop a comprehensive space system mission operations concept for the development and operations after the boost phase of a space mission is complete
17、d. Effective concept development relies on a development process that runs concurrently with the mission and flight element development efforts, balancing performance, cost, and risk issues. This International Standard is also applicable to the mission operations support to the pre-launch and launch
18、 phases of the mission using the mission operations systems. Standard products enable industry to develop commercial off-the-shelf tools for developing a space systems mission operations concept. This International Standard is specifically tailored for unmanned space missions and may be of partial u
19、se for human flight mission operations concepts. Users of this International Standard include project managers, operations personnel, flight element engineers, and operations facility personnel who are responsible for developing and integrating the mission operations system. This International Stand
20、ard lists items to be considered and defines the contents of a mission operations concept for space systems. This International Standard is applicable for the flow of data from the integration site and/or the launch pad to the operations centre and users, but does not include the items needed for a
21、launch operations concept. A space systems mission operations concept is prepared in parallel with the mission concept and flight element design and contains increasing levels of detail as the mission matures. During the early study phases, the operations concept is a high-level overview and contain
22、s many assumptions. As the mission operations concept evolves and advances to the approval stage, the content becomes more detailed with fewer documented assumptions. The space systems mission operations concept does not detail a missions development or operational costs, but is the basis of cost es
23、timation. Developing a space system mission operations concept early in the study phase helps to minimize life-cycle costs, make acceptable risk trades, and to determine the effectiveness of using existing system capabilities. The mission operations documentation and development costs are also reduc
24、ed as all the documents are referenced to a specific operations concept rather than a set of high-level project documents. The earlier the space systems mission operations concept is developed, the more leverage there is for influencing the operability of the entire mission system, including the fli
25、ght element. This International Standard establishes early in the projects development cycle a conceptual view of the mission data system which allows for a) early understanding of data and command transfer between sensors and end users, b) testing operational capabilities, and c) training personnel
26、 as the mission operation system matures. The development of the space system mission operations concept is most beneficial when done in parallel with the flight element design, thus creating a tight coupling between the two efforts performing trade studies in the areas of cost, performance and risk

34、eral The space systems mission operations concept is a result of a co-operative effort of the various project systems: flight element, ground support equipment system, mission operations system, launch vehicle, etc. Its development is closely coupled and is implemented in parallel with the developme
35、nt of the other project systems to produce a consistent and integrated mission operations concept. The space systems mission operations concept specifies design details and emphasises the way a mission is operated. It describes the operational characteristics of the space elements being controlled.
36、The space systems mission operations concept consists of mission documentation, constraints, and characteristics. It also contains the specific required mission operations products, including operational scenarios, time lines, processes performed by personnel, hardware and software processes, derive
37、d requirements, contingency scenarios, and conflict resolution processes. It also may contain a technology plan. End-user data products are specified and, depending on the mission, may be in various forms such as analogue, digital, and physical (e.g. sample return) data products. Another end user da
38、ta product received from the mission operations system should be a lessons-learned report to help future missions. A list of elements to be considered, defined, and generated when developing a space system mission operations concept is given in 3.2. Each item of the list is described further in 3.3.
39、 This guidance specifies the broadest scope of possible mission operations, tasks, issues, and products to facilitate mission managers and engineers in assessing the full scope of their mission operations concept. 3.2 Mission operations concept guidance 3.2.1 Inputs Define or make assumptions for th
