Space data and information transfer systems — Space link extension (SLE) — Forward communications li...
This document defines the Communications Link Transmission Unit (CLTU) service in conformance with the transfer services specified in reference [1], Cross Support Reference Model—Part 1: SLE Services. The Forward CLTU service is a Space Link Extension (SLE) transfer service that enables a mission to send Communications Link Transmission Units (CLTUs) to a spacecraft.
This document defines, in an…
Space data and information transfer systems — Attitude data messages
This document specifies two standard message formats for use in transferring spacecraft attitude information between space agencies: the Attitude Parameter Message (APM) and the Attitude Ephemeris Message (AEM). Such exchanges are used for:
- preflight planning for tracking or attitude estimation support;
- scheduling attitude and data processing support;
- carrying out attitude operations;
-…
Space data and information transfer systems — Space link extension — Application program interface f...
This document defines the Application Program Interface in terms of:
the components that provide the services of the API;
the functionality provided by each of the components;
the interfaces provided by each of the components; and
the externally visible behavior associated with the interfaces exported by the components.
It does not specify:
individual implementations or products;
the internal…
Ventilateurs — Classification du rendement des ventilateurs — Partie 5: Ventilateurs accélérateurs
Le présent document établit une classification du rendement de tous les types de ventilateurs entraînés par des moteurs dont la puissance électrique absorbée est comprise entre 5,5 kW et 155 kW (susceptibles de se situer dans une fourchette de 500 mm à 1600 mm de diamètre avec des moteurs d’une puissance nominale comprise entre 5,5 kW et 150 kW selon l’IEC 60034‑30‑1).
Le présent document n'…
Fans — Efficiency classification for fans — Part 5: Jet fans
This document establishes a classification of fan efficiency for all jet fan types driven by motors with an electrical input power range from 5,5 kW to 155 kW (and this is likely to be in the size range 500 mm to 1600 mm diameter with motors rated between 5,5 kW and 150 kW from IEC 60034-30-1).
This document is not applicable to jet fans for use in enclosed car parks.
This document can be used by…
Wheels and rims for pneumatic tyres — Vocabulary, designation and marking
This document presents a vocabulary of terms related to, and systems for the designation and marking of, wheels and rims intended for use with pneumatic tyres. The intention is to define fundamental wheel and rim terms rather than provide a comprehensive tabulation of all wheel design features. Also specified are the content, location and minimum size of the wheel and rim marking, with the…
Information technology — ASN.1 encoding rules — Part 8: Specification of JavaScript Object Notation ...
This document specifies a set of JavaScript Object Notation Encoding Rules (JER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1, Rec. ITU-T X.681 | ISO/IEC 8824-2, Rec. ITU-T X.682 | ISO/IEC 8824-3 and Rec. ITU-T X.683 | ISO/IEC 8824-4. It is implicit in the specification of these encoding rules that they are also to be used for…
Information technology — ASN.1 encoding rules — Part 4: XML Encoding Rules (XER)
This document specifies a set of basic XML Encoding Rules (BASIC-XER) that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1 and Rec. ITU-T X.681 | ISO/IEC 8824-2. This document also specifies a set of Canonical XML Encoding Rules (CXER) which provide constraints on the basic XML Encoding Rules and produce a unique encoding for any given ASN.…
Information technology — ASN.1 encoding rules — Part 3: Specification of Encoding Control Notation (...
This document defines a notation for specifying encodings of ASN.1 types or of parts of types.
It provides several mechanisms for such specification, including:
– direct specification of the encoding using standardized notation;
– specification of the encoding by reference to standardized encoding rules;
– specification of the encoding of an ASN.1 type by reference to an encoding…
Information technology — ASN.1 encoding rules — Part 2: Specification of Packed Encoding Rules (PER)
This document specifies a set of Packed Encoding Rules that may be used to derive a transfer syntax for values of types defined in Rec. ITU-T X.680 | ISO/IEC 8824-1. These Packed Encoding Rules are also to be applied for decoding such a transfer syntax in order to identify the data values being transferred.
The encoding rules specified in this document :
– are used at the time of…
