EN 16603-50:2022

Space engineering - Communications

This Standard specifies the requirements for the development of the end­to­end data communications system for spacecraft.
Specifically, this standard specifies:
- The terminology to be used for space communication systems engineering.
- The activities to be performed as part of the space communication system engineering process, in accordance with the ECSS-E-ST-10 standard.
- Specific requirements on space communication systems in respect of functionality and performance.
The communications links covered by this Standard are the space­to­ground and space­to­space links used during spacecraft operations, and the communications links to the spacecraft used during the assembly, integration and test, and operational phases.
Spacecraft end­to­end communication systems comprise components in three distinct domains, namely the ground network, the space link, and the space network. This Standard covers the components of the space link and space network in detail. However, this Standard only covers those aspects of the ground network that are necessary for the provision of the end­to­end communication services.
NOTE Other aspects of the ground network are covered in ECSS-E ST 70.
This Standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S ST 00.

Raumfahrttechnik - Kommunikation

Ingénierie spatiale - Communications

La présente norme spécifie les exigences de développement du système de communication de données de bout en bout pour les engins spatiaux.
En particulier, la présente norme spécifie :
• la terminologie à utiliser pour l'ingénierie des systèmes de communication spatiale ;
• les activités à mener dans le cadre du processus d'ingénierie des systèmes de communication spatiale, conformément à la norme ECSS-E-ST-10 ;
• des exigences spécifiques concernant les systèmes de communication spatiale en termes de fonctionnalité et de performances.
Les liaisons de communication traitées dans la présente norme sont les liaisons espace-sol (c’est-à-dire de l’espace vers le sol et du sol vers l’espace) et espace-espace utilisées pendant l’exploitation des engins spatiaux, et les liaisons de communications avec les engins spatiaux utilisées lors des phases d'assemblage, d'intégration et d'essais, et pendant les phases opérationnelles.
Les systèmes de communication de bout en bout des engins spatiaux comprennent des composants de trois catégories distinctes, à savoir le réseau sol, la liaison spatiale et le réseau spatial. La présente norme traite en détail des composants de la liaison spatiale et du réseau spatial. Toutefois, elle ne traite que des aspects du réseau sol qui sont nécessaires à la fourniture de services de communication de bout en bout.
NOTE Les autres aspects du réseau sol sont traités dans l'ECSS-E-ST-70.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques à un projet spatial, selon la norme ECSS-S-ST-00.

Vesoljska tehnika - Komunikacije

Ta standard določa zahteve za razvoj celovitega podatkovnega komunikacijskega sistema za vesoljska plovila.
Ta standard podrobno določa predvsem:
–   terminologijo, uporabljeno za inženiring za vesoljske komunikacijske sisteme;
–   dejavnosti, ki se izvajajo kot del inženirskega postopka za vesoljski komunikacijski sistem, v skladu s standardom ECSS-E-ST-10;
–   posebne zahteve za vesoljske komunikacijske sisteme glede funkcionalnosti in delovanja.
Komunikacijske povezave, zajete v tem standardu, so povezave vesolje-zemlja in vesolje-vesolje, ki se uporabljajo med operacijami vesoljskih plovil, in komunikacijske povezave do vesoljskega plovila, ki se uporabljajo v času sestave, integracije, preskušanja in upravljanja.
Celovite komunikacijske sisteme za vesoljska plovila sestavljajo tri različna področja: zemeljsko omrežje, povezava z vesoljem in vesoljsko omrežje. Ta standard podrobno zajema komponente povezave z vesoljem in vesoljskega omrežja. Vendar pa ta standard zajema le tiste vidike zemeljskega omrežja, ki so nujni za zagotavljanje celovitih komunikacijskih storitev.
OPOMBA:    Drugi vidiki zemeljskega omrežja so zajeti v standardu ECSS-E-ST-70.
Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
