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.

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 montaže, integracije, testiranja in delovanja. Celoviti komunikacijski sistemi za vesoljska plovila sestavljajo tri različna področja, in sicer 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.

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 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
