    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard specifies requirements for Guarantees of Origin of electricity from all energy sources and of Hydrogen. This standard will establish the relevant terminology and definitions, requirements for registration, issuing, transferring and cancellation in line with the RED and Cogeneration. This standard will specify how to create accounts and associated ownership rights. This standard will also cover measuring methods and auditing procedures. These Guarantees of Origin may be traded and/or used for Disclosure/Labelling. This standard is suitable for certification purposes. This standard will specify the requirements on the issuing bodies and on the auditing bodies.

    Beskrivelse
    The purpose of this Standard is to define the Factors Of Safety (FOS), Design Factor and additional factors to be used for the dimensioning and design verification of spaceflight hardware including qualification and acceptance tests. This standard is not self standing and is used in conjunction with the ECSS-E-ST-32, ECSS-E-ST-32-02 and ECSS-E-ST-33-01 documents. Following assumptions are made in the document: - that recognized methodologies are used for the determination of the limit loads, including their scatter, that are applied to the hardware and for the stress analyses; - that the structural and mechanical system design is amenable to engineering analyses by current state-of-the-art methods and is conforming to standard aerospace industry practices. Factors of safety are defined to cover chosen load level probability, assumed uncertainty in mechanical properties and manufacturing but not a lack of engineering effort. The choice of a factor of safety for a program is directly linked to the rationale retained for designing, dimensioning and testing within the program. Therefore, as the development logic and the associated reliability objectives are different for: - unmanned scientific or commercial satellite, - expendable launch vehicles, - man-rated spacecraft, and - any other unmanned space vehicle (e.g. transfer vehicle, planetary probe) specific values are presented for each of them. Factors of safety for re-usable launch vehicles and man-rated commercial spacecraft are not addressed in this document. For all of these space products, factors of safety are defined hereafter in the document whatever the adopted qualification logic: proto-flight or prototype model. For pressurized hardware, factors of safety for all loads except internal pressure loads are defined in this standard. Concerning the internal pressure, the factors of safety for pressurised hardware can be found in ECSS-E-ST-32-02. For loads combination refer to ECSS-E-ST-32-02. For mechanisms, specific factors of safety associated with yield and ultimate of metallic materials, cable rupture factors of safety, stops/shaft shoulders/recess yield factors of safety and limits for peak Hertzian contact stress are specified in ECSS-E-ST-33-01. Alternate approach The factors of safety specified hereafter are applied using a deterministic approach i.e. as generally applied in the Space Industry to achieve the structures standard reliability objectives. Structural safety based on a probabilistic analysis could be an alternate approach but it has to be demonstrated this process achieves the reliability objective specified to the structure. The procedure is approved by the customer. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

    Space data and information transfer systems – Orbit data messages

    Oprindelse:
    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    ISO 26900:2012 specifies three standard message formats for use in transferring spacecraft orbit information between space agencies and commercial or governmental spacecraft operators: the Orbit Parameter Message (OPM), the Orbit Mean-Elements Message (OMM), and the Orbit Ephemeris Message (OEM). Such exchanges are used for a) pre-flight planning for tracking or navigation support, b) scheduling tracking support, c) carrying out tracking operations (sometimes called metric predicts), d) performing orbit comparisons, e) carrying out navigation operations such as orbit propagation and orbit reconstruction, f) assessing mutual physical and electromagnetic interference among satellites orbiting the same celestial body (currently primarily Earth, Moon, and Mars), g) performing orbit conjunction (collision avoidance) studies, and h) developing and executing collaborative manoeuvres to mitigate interference or enhance mutual operations. ISO 26900:2012 includes sets of requirements and criteria that the message formats have been designed to meet.
