The scope of the SpaceFibre standard is the detailed specification a very high-speed serial link protocol stack reaching from link level Quality layer  down to the Physical layer. The higher layers like packet, network and higher level protocols are the same as for SpaceWire and specified in the respective standards ECSS-E-ST-50-12C and ECSS-E-ST-50-51C to 53C.

This standard specifies the requirements, also known as "relifing requirements", for the planned, intentional storage, control, and removal from storage of electronic, electrical and electromechanical parts which are intended to be used for space applications.
This standard covers the relifing of all components as defined by ECSS-Q-ST-60 and ECSS-Q-ST-60-13.
The relifing process is a lot quality control activity.  The inspections and tests defined do not constitute an up-screening or up-gradin...view more

It defines the terminology for the activities within these areas.
It defines the specific requirements for electrical subsystems and payloads, deriving from the system engineering requirements laid out in ECSS-E-ST-...view more

This activity will be the update of EN16603-20-06 (published 2014).
This activity was started in ECSS to implement as urgent classified Change Requests.

This Standard specifies star sensor performances as part of a space project. The Standard covers all aspects of performances, including nomenclature, definitions, and performance requirements for the performance specification of star sensors.
The Standard focuses on:
- performance specifications (including the impact of temperature, radiation and straylight environments);
- robustness (ability to maintain functionalities under non nominal environmental conditions).

1.1   Purpose:
The "Scheduling and Commanding Messages" (SCM) specifies a standard format for observing system commanding and scheduling. This document aims to ease the planning and operation processes and to reduce the effors from researchers that use several different observing systems and/or simulation software products.
The SCM establishes a common language for exchanging information on planning, scheduling, and executing observations of celestial objects. In the end this will:
a)   Facilitat...view more

1.1   Purpose:
The Observing System Data Message (OSDM) is a standard message format to be used in the exchange of optical telescope, laser ranging station, and radar (observing systems) information between Space situational Awareness (SSA) data providers, owners/operators of observing systems, and other parties. These messages can inform SSA data providers, which are the consumers of observing system output data, on the parameters of the observing systems.
The OSDM standard will:
a)   enable con...view more

This document establishes general test requirements for launch vehicles equipped with liquid-propellant engines, launched from stationary ground-, sea- and air-based launchers, in all phases of their development.

This document provides requirements for launch system designers or interface designers regarding interfaces between LV and EGSE, which is used to support on-line processing. It defines electrical interface types, design requirements, environment requirements, verification methods (analyses and tests), and interface check operation requirements. This document is intended to minimize design costs and reduce risks from errors resulting from miscommunication. It does not limit LV or EGSE organizatio...view more

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,...view more

In general terms, the scope of the consolidation of the electrical interface
requirements for electrical (hold down and release or deployment) actuators in
the present ECSS-E-ST-20-21 and the relevant explanation in the handbook
ECSS-E-HB-20-21 is to allow a more recurrent approach both for actuator
electronics (power source) and electrical actuators (power load) offered by the
relevant manufacturers, at the benefit of the system integrators and of the
Agency, thus ensuring:
• better qual...view more

The document defines the requirements for the interfaces of simulation models between simulation
environments.

This document regards the test procedures for assessment of robustness to security attacks.
Starting from the definition of security attacks taxonomy and security metrics, this TR aims to:
1. Specify test facilities to be used in the tests of GPBT. This comprises both hardware and software equipment.
2. Define relevant test scenarios applicable to security performances. Also the field test needed for validation of scenarios will be properly described.
3. Define end-to-end test procedures com...view more
