Space product assurance - Software dependability and safety

This Handbook provides guidance on the application of the dependability and safety requirements relevant to software defined in EN 16602-80 (equivalent of ECSS-Q-ST-80).
This Handbook provides support for the selection and application of software dependability and safety methods and techniques that can be used in the development of software-intensive space systems.
This Handbook covers all of the different kinds of software for which EN 16602-80 (equivalent of ECSS-Q-ST-80) is applicable. Although the overall software dependability and safety workflow description is mainly targeted to the development of spacecraft, the described approach can be adapted to projects of different nature (e.g. launchers, ground systems).
The methods and techniques described in the scope of this Handbook are limited to assessment aspects, not including development and implementation techniques for dependability and safety (e.g. fault tolerance techniques, or development methods like coding standards, etc.).
Although dependability is a composite term, including reliability, availability and maintainability, this Handbook addresses in particular the reliability aspects. Software maintainability and availability are not covered in depth by this handbook, because the relevant methods and techniques are still undergoing improvement. Nevertheless, whenever a link can be made to either of these two characteristics, it is explicitly mentioned in the corresponding section.

Space product assurance - Software metrication programme definition and implementation

SIST-TP CEN/CLC/TR 17602-80-04:2021

The scope of this Handbook is the software metrication as part of a space project, i.e. a space system, a subsystem including hardware and software, or ultimately a software product. It is intended to complement the EN 16602-80 (equivalent to ECSS-Q-ST-80) with specific guidelines related to use of different software metrics including their collection, analysis and reporting. Tailoring guidelines for the software metrication process are also provided to help to meet specific project requirements.
This Handbook provides recommendations, methods and procedures that can be used for the selection and application of appropriate metrics, but it does not include new requirements w ith respect to those provided by EN 16602-80 (equivalent to ECSS-ST-Q-80).
The scope of this Handbook covers the following topics:
• Specification of the goals and objectives for a metrication programme.
• Identification of criteria for selection of metrics in a specific project / environment (goal driven).
• Planning of metrication in the development life cycle.
• Interface of metrication with engineering processes.
• Data collection aspects (including use of tools).
• Approach to the analysis of the collected data.
• Feedback into the process and product based on the analysis results.
• Continuous improvement of measurement process.
• Use of metrics for process and product improvement.
This Handbook is applicable to all types of software of all major parts of a space system, including the space segment, the launch service segment and the ground segment software.

Space product assurance - Reuse of existing software

SIST-TP CEN/CLC/TR 17602-80-01:2021

This handbook provides recommendations, methods and procedures that can be used for the selection and reuse of existing software in space software systems.
This handbook is applicable to all types of software of a space system, including the space segment, the launch service segment and the ground segment software (including EGSEs) whenever existing software is intended to be reused within them.
This handbook covers the following topics:
• Software reuse approach including guidelines to build the Software Reuse File
• Techniques to support completion of existing software qualification to allow its reuse in a particular project
• Tool qualification
• Risk management aspects of reusing existing software Existing software can be of any type: Purchased (or COTS), Legacy-Software, open-source software, customer-furnished items (CFI's), etc.
NOTE Special emphasis is put on guidance for the reuse of COTS software often available as-is and for which no code and documentation are often available.
Legal and contractual aspects of reuse are in principle out of scope; how ever guidelines to help in determine the
reusability of existing software from a contractual point of view is provided in [ESA/REG/002].
Any organization with the business objective of systematic reuse may need to implement the organizational reuse processes presented in [ISO12207]. These processes w ill support the identification of reusable software products and components within selected reuse domains, their classification, storage and systematic reuse within the projects of that organization, etc. But these processes are out of scope of this handbook as the handbook is centred on the specific project activities to reuse an existing software product, not part of those organizational reuse processes more oriented to ‘design for reuse’ processes.
In addition, this handbook provides guidelines to be used for the selection and analysis of tools for the development, verification and validation of the operational software.

Space - Space Situational Awareness Monitoring - Part 30-03: Observation System Data Message (OSDM)

SIST EN 16604-30-03:2020

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 consistent data exchange between observation data providers and SSA systems;
b)   facilitate data exchange automation and ingestion of observation data from different providers;
c)   facilitate SSA system architecture performance simulations; and
d)   provide a quick way to estimate the expected performance from one observing system.
1.2   Applicability:
The Observing System Data Message standard is applicable to all SSA activities, especially Space Surveillance and Tracking (SST) as well as near-Earth objects (NEO), and other fields where the acquisition of astrometric and photometric data plays a role (e.g. space debris, observational astronomy). The standard contains a message designed to contain observing system parameters exchanged between producers and consumers of astrometric and/or photometric data. These data include observing system name, location, type (optical/radar), operator and tracking/survey performance.
The OSDM is suitable for both manual and automated interaction, but will not contain a large amount of data. The message is self contained and can be paired with several Tracking Data Messages (TDM – specified reference [1]), FITS images (specified in reference [2]), or other formats containing the observation data.
The OSDM standard only applies to the message format, structure and content. The exchange method is beyond the scope of the standard, and it is due to be specified in an ICD, though an ICD is not always required. The methods used to produce the data in the message are also beyond the scope of the standard.
1.3   Document structure:
Clause 5 provides an overview of the OSDM.
Clause 6 described the structure and content of the 'keyword = value' (KVN) version of the OSDM.
Clause 7 described the structure and content of the XML version of the OSDM.
Clause 8 describes the data and syntax of OSDM messages, in both KVN and XML.
Annex A lists agreed values for some of the OSDM keywords.
Annex B presents some examples of OSDMs.

Space engineering - Exchange of thermal analysis data

SIST EN 16603-31-04:2019

The purpose of this NWIP is to produce an ECSS standard for the Exchange of Thermal Model Data for Space Applications. The standard will be based on a draft standard resulting from an activity performed by ESA only in 2013/2014 called "Standard for Exchange of Thermal Model Data for Space Applications".
The content of the standard is already defined in draft form under the name "STEP-TAS" ("STEP-based draft application protocol for Thermal Analysis for Space"). This protocol has been implemented in a number of thermal analysis tools and is successfully used in both ESA and non-ESA space projects. The maturity of the protocol is therefore well-established.
The global objective of this document is to define and describe the standard protocol for Exchange of Thermal Model Data for Space Applications, previously known as STEP-TAS protocol.
