20、nical Committee CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN. This standard (EN 16603-10-09:2014) originates from ECSS-E-ST-10-09C. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by

21、 January 2015, and conflicting national standards shall be withdrawn at the latest by January 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such p

22、atent rights. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of

23、the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Nethe

25、ineering process. Problems caused by inadequate early definition, often pass unnoticed during the exchange of technical information. This Standard addresses this by separating the technical aspects from the issues connected with process, maintenance and transfer of such information. Clause 4 provide

26、s some explanation and justification, applicable to all types of space systems, missions and phases. Clause 5 contains the requirements and recommendations. Helpful and informative material is provided in the Annexes. BS EN 16603-10-09:2014EN 16603-10-09:2014 (E) 7 1 Scope The objective of the Coord

27、inate Systems Standard is to define the requirements related to the various coordinate systems, as well as their related mutual inter-relationships and transformations, which are used for mission definition, engineering, verification, operations and output data processing of a space system and its e

28、lements. This Standard aims at providing a practical, space-focused implementation of Coordinate Systems, developing a set of definitions and requirements. These constitute a common reference or “checklist” of maximum utility for organising and conducting the system engineering activities of a space

29、 system project or for participating as customer or supplier at any level of system decomposition. This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

43、.2 Concepts and processes 4.2.1 Process The coordinate systems used within a project are identified early in the lifecycle of a project. These coordinate systems are then related via a chain of transformations to allow the transformation of coordinates, directions and other geometric parameters into

44、 any coordinate system used within the project at any time in the project life. 4.2.2 Documentation Besides the ICDs, CAD drawings and SRD, a specific document for all coordinate systems and their inter-relationships, throughout the product tree and the project life, are created, maintained and conf

45、igured. The Coordinate System Document (CSD) takes shape before the end of phase-A. 4.2.3 Coordinate system chain analysis A chain of transformations is constructed using chain elements or links. A link is composed of two coordinate systems together with the transformation between them. The product

46、tree can be mapped into a set of connected chains. For any analysis, the appropriate connected chain is used, even if other paths within the tree are later found to be useful for satellite integration, operations or processing. For subsystem or unit analysis, any link may be decomposed into a sub-ch

47、ain containing intermediate coordinate systems. The relationship between two coordinate systems can involve kinematics, dynamics, measurement or constraints. See Annex B for some examples. BS EN 16603-10-09:2014EN 16603-10-09:2014 (E) 13 The main mission chain typically includes inertial, rotating p

48、lanet-centred orbital, spacecraft mechanical, instrument and product (i.e. post-processing related) coordinate systems.” 4.2.4 Notation Experts working together within a project need to have a common understanding of the parameters and variables. Specific coordinate systems are used to obtain a conv

49、enient formulation of the kinematic and dynamic equations involved. A shared understanding of all the coordinate systems and their parameterisations is therefore paramount. This necessitates the definition of a notational convention for naming variables, coordinate systems and their inter-relationships. 4.3 Technical issues 4.3.1 Frame and coordinate system Transformations between frames, having orthogonal axes, the same handedness (right or left) and unit vectors along each axis, enjoy the properties of unitary matrices, which facilitate the calculation of i
