22、32:2014) has been prepared by Technical Committee CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN. This standard (EN 16603-70-32:2014) originates from ECSS-E-ST-70-32C. This European Standard shall be given the status of a national standard, either by publication of an identical text o
23、r by endorsement, at the latest by March 2015, and conflicting national standards shall be withdrawn at the latest by March 2015.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
24、 identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same
25、 scope but with a wider domain of applicability (e.g. : aerospace). According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark,
26、Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

27、014EN 16603-70-32:2014 (E) 6 Introduction The procedure is the principal mechanism employed by the end-user to control the space system during pre-launch functional testing and post-launch in-orbit operations. This Standard identifies the requirements to be satisfied by any language used for the dev
28、elopment of automated test and operation procedures. It also defines a reference language that fulfils these requirements. This language is called the “procedure language for users in test and operations (PLUTO)”. BS EN 16603-70-32:2014EN 16603-70-32:2014 (E) 7 1 Scope This Standard specifies: The c
29、apabilities of the language used for the definition of procedures for space system testing and operations. The PLUTO language. Clause 4 defines the context in which procedures operate. Clause 5 contains the requirements for the procedure language. Annex A specifies the PLUTO language. This includes:
30、 The “building blocks” that constitute procedures and the role that each of these building blocks plays in achieving the overall objectives of the procedure. The dynamic aspects of procedures i.e. the execution logic of each building block and execution relationships between these blocks. The syntax
31、 and semantics of the language itself. Annex B specifies the engineering units to be supported by the procedure language. Annex C specifies the mathematical, time and string functions to be supported by the procedure language. This standard may be tailored for the specific characteristics and constr
32、aints of a space project in conformance with ECSS-S-ST-00.
