(Main)Space engineering - System engineering general requirements
Space engineering - System engineering general requirements
This standard specifies the system engineering implementation requirements for space systems and space products development.
Specific objectives of this standard are:
• to implement the system engineering requirements to ensure a firm technical basis and to minimize technical risk and cost for space systems and space products development;
• to specify the essential system engineering tasks, their objectives and outputs;
• to implement integration and control of engineering disciplines and lower level system engineering work;
• to implement the “customer-system-supplier model” through the development of systems and products for space applications.
This Standard is intended to apply to all space systems and product, at any level of the system decomposition, including hardware, software, procedures, man-in-the-loop, facilities and services. Through the document and its annexes the requirements however apply as they are to complex systems only; for lower level elements tailoring is necessary.
Specific requirements related to system engineering, like technical specification, verification, and testing are specified in dedicated documents and standards within the set of ECSS system engineering standards ECSS-E-ST-10-XX.
Discipline or element specific engineering implementation requirements are covered in dedicated ECSS standards. These standards are based on the same principles, process and documentation model. The applicability of each these standards can therefore not be considered in isolation from the others.
ECSS-E-HB-10 “System engineering guidelines” contains guidelines related to this standard, including a description of the reference system engineering process for a space system and its products.
NOTE 1 The term “Discipline” is defined in ECSS-M-ST-10, as “a specific area of expertise within a general subject”. The name of the discipline normally indicates the type of expertise, e.g. in the ECSS system mechanical engineering, software and communications are disciplines within the engineering domain.
NOTE 2 The requirements on the system engineering process are gathered in this standard; specific aspects of the SE process are further elaborated in dedicated standards.
This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
Raumfahrttechnik - Grundsätze und Verfahrensweise
Ingénierie spatiale - Exigences générales d'ingénierie système
La présente Norme expose les exigences de mise en oeuvre de l’ingénierie système pour le développement des systèmes et des produits spatiaux.
Les objectifs précis de la présente Norme sont les suivants :
- appliquer les exigences d’ingénierie système pour créer une base technique solide et minimiser les coûts et les risques techniques pour le développement des systèmes et des produits spatiaux ;
- définir les principales tâches d’ingénierie système, leurs objectifs et leurs résultats ;
- mettre en oeuvre l’intégration et le contrôle des disciplines d’ingénierie, ainsi que les travaux d’ingénierie système de niveau inférieur ;
- mettre en oeuvre le « modèle client-système-fournisseur » à travers le développement de systèmes et de produits pour les applications spatiales.
En fonction de la catégorie de produit, il faut vérifier si la présente norme doit être appliquée et si besoin adaptée. Le tableau de préadaptation de l’article 7 présente l’applicabilité des exigences du présent document et de ses annexes selon le type de produit. Les exigences spécifiques relatives à l’ingénierie système, telles que les spécifications techniques, la vérification et les essais, sont spécifiées dans des documents et normes dédiés de la série ECSS-E-ST-10-XX, relative à l’ingénierie système de l’ECSS.
Les exigences de mise en oeuvre de l’ingénierie propres à chaque discipline ou à chaque élément sont décrites dans les normes ECSS associées. Ces normes se fondent sur les mêmes principes, les mêmes processus et le même modèle de documentation. L’applicabilité de chacune de ces normes ne peut donc être envisagée de manière indépendante.
NOTE 1 Le terme « Discipline » est défini dans l’ECSS-M-ST-10 comme étant une « spécialité entrant dans le cadre d’un sujet général ». Le nom de la discipline indique généralement le type d’expertise auquel elle est associée ; par exemple, dans le système ECSS, l’ingénierie mécanique, les logiciels et les communications sont des disciplines du domaine de l’ingénierie.
NOTE 2 Les exigences relatives au processus d’ingénierie système sont réunies dans cette norme ; les aspects spécifiques au processus d’ES sont décrits de façon plus détaillée dans des normes dédiées.
En matière de processus d’ingénierie relatif aux logiciels ainsi qu’au segment sol et aux opérations, les normes suivantes sont considérées comme étant amplement suffisantes pour le développement de ces articles :
- ECSS-E-ST-70 Ingénierie spatiale - Systèmes sol et opérations
- ECSS-E-ST-40 Ingénierie spatiale - Logiciels
- ECSS-Q-ST-80 Assurance produit des projets spatiaux - Assurance produit logiciel
La présente Norme peut être adaptée aux caractéristiques et contraintes spécifiques d’un projet spatial, conformément à l’ECSS-S-ST-00.
Vesoljska tehnika - Sistemskotehnične splošne zahteve
Ta standard določa zahteve za izvajanje sistemskega inženiringa za vesoljske sisteme in razvoj vesoljskih izdelkov. Namen tega standarda je zlasti: • izvajanje zahtev za sistemski inženiring z namenom zagotavljanja trdne tehnične podlage in zmanjševanja tehničnih tveganj in stroškov vesoljskih sistemov ter razvoja vesoljskih izdelkov; • določanje bistvenih nalog sistemskega inženiringa ter njihovih ciljev in rezultatov; • izvajanje povezovanja in nadzora nad različnimi inženirskimi disciplinami in dela v zvezi s sistemskim inženiringom na nižji ravni; • izvajanje »modela odjemalec-sistem-dobavitelj« s pomočjo razvoja sistemov in izdelkov za vesoljske aplikacije. Ta standard je namenjen za uporabo pri vseh vesoljskih sistemih in izdelkih, na kateri koli ravni razstavljanja sistema, vključno s strojno opremo, programsko opremo, postopki, modeli z vključitvijo človeka, objekti in storitvami. V celotnem dokumentu in njegovih dodatkih zahteve kot take veljajo samo za kompleksne sisteme; za elemente nižje ravni je potrebna prilagoditev. Posebne zahteve v zvezi s sistemskim inženiringom, kot so tehnične specifikacije, preverjanje in preskušanje, določajo namenski dokumenti in standardi v sklopu standardov ECSS za sistemski inženiring ECSS-E-ST-10-XX. Zahteve za izvajanje inženiringa, vezanega na discipline ali elemente, so zajete namenskih standardih ECSS. Navedeni standardi temeljijo na enakih načelih, procesu in modelu dokumentiranja. Zato uporabnosti posameznega standarda ni mogoče presojati ločeno od ostalih standardov. Dokument ECSS-E-HB-10 »Smernice za sistemski inženiring« vsebuje smernice, ki se navezujejo na ta standard, vključno z opisom postopka inženiringa za vesoljski sistem in njegove izdelke. OPOMBA 1: izraz »disciplina« je v standardu ECSS-M-ST-10 opredeljen kot »določeno strokovno področje v okviru splošne tematike«. Iz imena discipline je običajno razvidna vrsta strokovnega znanja, npr. v okviru mehanskega inženiringa sistema ECSS sta programska oprema in komunikacije disciplini s področja inženiringa. OPOMBA 2: v tem standardu so zajete zahteve za postopek sistemskega inženiringa; posebni vidiki postopka sistemskega inženiringa so natančneje določeni v namenskih standardih. Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.

European Foreword
This document (EN 16603-10:2018) has been prepared by Technical Committee CEN-CENELEC/JTC 5
“Space”, the secretariat of which is held by DIN.
This standard (EN 16603-10:2018) originates from ECSS-E-ST-10C Rev.1.
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 October 2018, and conflicting national standards shall
be withdrawn at the latest by October 2018.
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
patent rights.
This document supersedes EN 13292:1999, EN 14514:2004 and EN 14607-7:2004.
The main changes with respect to EN 13292:1999, EN 14514:2004 and EN 14607-7:2004 are:
• The main driver for the changes in this issue of the standard comes from the intention to include in
this document only requirements and remove all informative material related to the process for
inclusion in a future handbook.
• Inclusion of EN 16603-11 (ECSS-E-AS-11) "Adoption Notice of ISO 16290, Space systems -
Definition of the Technology Readiness Levels (TRLs) and their criteria of assessment" as
Normative Reference.
• Former clause 5 “System engineering process”, replaced by a brief overview of the project phases
and related system engineering tasks in the current clause 4.3 “Overview of system engineering
tasks per project phase”.
• Former Clause 4 split into an introductory clause 4 “Overview of Systems engineering” and clause
5 “General Requirements”.
• Clause 7 "Pre-tailoring matrix per space product types" added
• The remaining requ irements have been reworded for readability and consistency. Repetition of
requirements included in other related standards have been eliminated.
• Regarding the documentation model, the only significant modification originates in the
simplification of the concept of Functional Specification and Technical Specification. In EN 16603-
10-06 only one specification, the technical requirements specification (customer specification), is
considered. This is reflected in this standard, as explained in clause 5.2.3.1
• Annex A: System engineering documents delivery per review: This annex replaces and expands
old Annex B. It includes the listing of the main documents per phase of the project development
indicating when the document needs to be available.
• Document Requirements Descriptions (DRD) added in several Annexes that include all the project
documents pertinent to this standard. In the previous issue the DRDs were not included.

EN 16603-10:2018 (E)
• Annex R: Mapping of typical DDP to ECSS documents: This is an addition with respect to the
previous issue. It presents where specific subjects contained in the previously used Design and
Development Plan are located in the new set of ECSS documents.
This document has been prepared under a standardization request 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 scope but with a wider domain of applicability (e.g. : aerospace).
According to the CEN-CENELEC Internal Regulations, the national standards organisations of 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, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia,
Spain, Sweden, Switzerland, Turkey and the United Kingdom.

Scope
This standard specifies the system engineering implementation requirements
for space systems and space products development.
Specific objectives of this standard are:
• to implement the system engineering requirements to establish a firm
technical basis and to minimize technical risk and cost for space systems
and space products development;
• to specify the essential system engineering tasks, their objectives and
outputs;
• to implement integration and control of engineering disciplines and
lower level system engineering work;
• to implement the “customer-system-supplier model” through the
development of systems and products for space applications.
Depending of the product category, the application of this standard needs to be
checked and if needed tailored. The pre-tailoring table in clause 7 contains the
applicability of the requirements of this document and its annexes according to
product type. Specific requirements related to system engineering, like technical
specification, verification, and testing are specified in dedicated documents and
standards within the set of ECSS system engineering standards ECSS-E-ST-10-XX.
Discipline or element specific engineering implementation requirements are
covered in dedicated ECSS standards. These standards are based on the same
principles, process and documentation model. The applicability of each these
standards can therefore not be considered in isolation from the others.
NOTE 1 The term “Discipline” is defined in ECSS-M-ST-10, as “a
specific area of expertise within a general subject”. The
name of the discipline normally indicates the type of
expertise, e.g. in the ECSS system mechanical
engineering, software and communications are
disciplines within the engineering domain.
NOTE 2 The requirements on the system engineering process are
gathered in this standard; specific aspects of the SE
process are further elaborated in dedicated standards.
For engineering process both for SW and for Ground Segment and Operations
the following standards are considered fully sufficient for development of these
items:
• ECSS-E-ST-70 Space engineering - Ground systems and operations
• ECSS-E-ST-40 Space engineering - Software

Overview of system engineering
4.1 The system engineering discipline
System engineering is an interdisciplinary approach governing the total
technical effort to transform requirements into a system solution.
A system is an integrated set of elements to accomplish a defined objective.
These elements include hardware, software, firmware, human resources,
information, techniques, facilities services, and other support elements.
In this standard the concept of “system” is used in a wide sense. The highest
level, often called “mission level” or “space system”, consists usually of one (or
more) space segment(s), of a ground segment, and of a user segment. Elements
of system decomposition are also considered a system. For the purpose of this
standard the system can be any element at any level of decomposition as
defined by the function tree (see Annex H) or the product tree (see ECSS-M-ST-
10 Annex B). The scope of an element can include hardware, software,
procedures, man-in-the-loop, facilities and services.
From the perspective of the considered system, requirements originate from the
next upper level (the customer) and elements are procured from the next lower
level (the suppliers).
NOTE 1 The customer-supplier model is described in
ECSS-S-ST-00.
NOTE 2 Through this standard the notion of customer
refers to several actors ,in relation to the project
phase. In fact a customer can be e.g. a scientific
community in phase 0, a commercial user in
phase A or an Agency in phase B. A supplier can
on the other hand be an Agency in both phase 0
and phase A.
Figure 4-1 shows the boundaries of system engineering (for which the indicated
interactions between the identified major disciplines is not exhaustive but
indicative), its relationship with production, operations, product assurance and
management disciplines (and their cross-interaction is indicated as “interface
areas” in the figure) and its internal partition into the following system
engineering sub-functions:
• requirement engineering, which consist on requirement analysis and

Scope
This standard specifies the system engineering implementation requirements
for space systems and space products development.
Specific objectives of this standard are:
• to implement the system engineering requirements to establish a firm
technical basis and to minimize technical risk and cost for space systems
and space products development;
• to specify the essential system engineering tasks, their objectives and
outputs;
• to implement integration and control of engineering disciplines and
lower level system engineering work;
• to implement the “customer-system-supplier model” through the
development of systems and products for space applications.
Generally, System Engineering is a discipline that can find beneficial application
to the development and production of a wide variety of systems and throughout
the product decomposition hierarchy. However the requirements in this Standard
were developed to be appropriate for application as they are to complex space
systems and products only; for lower level elements tailoring is necessary. The
pre-tailoring table in Section 7 contains the applicability of the requirements of
this document and its annexes according to product type.Specific requirements
related to system engineering, like technical specification, verification, and testing
are specified in dedicated documents and standards within the set of ECSS
system engineering standards ECSS-E-ST-10-XX.
Discipline or element specific engineering implementation requirements are
covered in dedicated ECSS standards. These standards are based on the same
principles, process and documentation model. The applicability of each these
standards can therefore not be considered in isolation from the others.
NOTE 1 The term “Discipline” is defined in ECSS-M-ST-10, as “a
specific area of expertise within a general subject”. The
name of the discipline normally indicates the type of
expertise, e.g. in the ECSS system mechanical
engineering, software and communications are
disciplines within the engineering domain.
NOTE 2 The requirements on the system engineering process are
gathered in this standard; specific aspects of the SE
process are further elaborated in dedicated standards.
This standard may be tailored for the specific characteristic and constrains of a
space project in conformance with ECSS-S-ST-00.

Overview of system engineering
4.1 The system engineering discipline
System engineering is defined as an interdisciplinary approach governing the
total technical effort to transform requirements into a system solution.
A system is defined as an integrated set of elements to accomplish a defined
objective. These elements include hardware, software, firmware, human
resources, information, techniques, facilities services, and other support
elements.
In this standard the concept of “system” is used in a wide sense. The highest
level, often called “mission level” or “space system”, consists usually of one (or
more) space segment(s), of a ground segment, and of a user segment. Elements
of system decomposition are also considered a system. For the purpose of this
standard the system can be any element at any level of decomposition as
defined by the function tree (see Annex H) or the product tree (see ECSS-M-ST-
10 Annex B). The scope of an element can include hardware, software,
procedures, man-in-the-loop, facilities and services.
From the perspective of the considered system, requirements originate from the
next upper level (the customer) and elements are procured from the next lower
level (the suppliers).
NOTE 1 The customer-supplier model is described in
ECSS-S-ST-00.
NOTE 2 Through this standard the notion of customer
refers to several actors ,in relation to the project
phase. In fact a customer can be e.g. a scientific
community in phase 0, a commercial user in
phase A or an Agency in phase B. A supplier can
on the other hand be an Agency in both phase 0
and phase A.
Figure 4-1 shows the boundaries of system engineering, its relationship with
production, operations, product assurance and management disciplines and its
internal partition into the following system engineering sub-functions:
• requirement engineering, which consist on requirement analysis and
validation, requirement allocation, and requirement maintenance;
• analysis, which is performed for the purpose of resolving requirements
conflicts, decomposing and allocating requirements during functional
analysis, assessing system effectiveness (including analysing risk factors);
12
---------------------- Page: 14 ----------------------
kSIST FprEN 16603-10:2016
FprEN 16603-10:2016 (E)
and complementing testing evaluation and providing trade studies for
assessing effectiveness, risk, cost and planning;
• design and configuration which results in a physical architecture, and its
complete system functional, physical and software characteristics;
• verification, which objective is to demonstrate that the deliverables
conform to the specified requirements, including qualification and
acceptance;
• system engineering integration and control, coordinating the various
engineering disciplines and participants throughout all the project
phases.
Figure 4-2 shows system engineering sub-functions, their inter-relationships
and their main activities during the system engineering process.
System engineering sub-functions are applied in an iterative mode during
implementation of the system engineering process described in clause 4.2.
Within the frame of a project, the system engineering function is generally
implemented by a system engineering organisation of the supplier which is in
charge of transforming the requirements of the customer into a system solution
delivered by the supplier. For the purpose of this standard, the ‘system
engineering function’ only is referred to in the normative statements,
independent of whether the supplier has a formal ‘system engineering
organisation’ or not.
NOTE With respect to the next lower level, the
supplier plays the role of the customer.

4.2 The system engineering process
The system engineering activities of a project are conducted by an entity or
resources within the project team of a supplier. This entity or the resources that
perform this function is called in this document “system engineering function”.
The system engineering process is in turn applied by each system engineering
function of each supplier of the elements of the product decomposition.
The system engineering process consists of activities to be performed by the
system engineering function within each project phase. The objective is to
obtain a product which satisfies the customer technical requirements within
pre-established objectives of cost and time. The requirements for these activities
are described in clause 5.
The system engineering process is intrinsically iterative across the whole life of
a project, in particular in the initial phases (i.e. 0, A, and B) of the development
of a complex system (e.g. a spacecraft), procured through a multi-layered set of
suppliers.
During these phases, the system engineering function derives design oriented
technical solutions using as an input to the design-independent customer
requirements contained in a technical requirements specification (TS). This is
achieved through an iterative top-down process by trading off several design
solutions at an increasing level of detail.
NOTE For definition and requirements for a technical
requirements specification see ECSS-E-ST-10-06.
Through this process the system engineering function performs a
multidisciplinary functional decomposition to obtain logical lower level
products (both hardware and software). At the same time the system
engineering function decides on balanced allocations, throughout the system, of
resources allocated by the customer and respects agreed margin philosophies as
a function of the relevant technology readiness levels.
The functional decomposition defines, for each level of the system, the technical
requirements for the procurement of subassemblies or lower level products as
well as the requirements for the verification of the final characteristics of each
product.
The system engineering process uses the results of these lower level verification
activities to build a bottom-up multi-layered evidence that the customer
requirements have been met.
The system engineering process is applied with various degrees of depth
depending on the level of maturity of the product (e.g. new development or off-
the-shelf).
The system engineering process can be applied with different level of tailoring
as agreed between customer and supplier in their business agreement.
The system engineering function has interfaces with those other functions in
charge of management, product assurance, engineering disciplines, production,
and operations and logistics.
NOTE The project phases are defined in ECSS-M-ST-
10.

4.3 Overview of system engineering tasks per project
phase
4.3.1 Overview
The allocation of specific system engineering requirements per phase depends
strongly on the type of business agreement established between customer and
supplier and the nature and level of complexity of the system subject of the
agreement. The breakdown and the details of the tasks are defined in the
business agreement specific documents.

work (SoW).
