Space engineering - Space data links - Telemetry synchronization and channel coding

This Standard establishes a common implementation of space telemetry channel coding systems.
Several space telemetry channel coding schemes are specified in this Standard. The specification does not attempt to quantify the relative coding gain or the merits of each scheme, nor the design requirements for encoders or decoders. However, some application profiles are discussed in Annex D. Performance data for the coding schemes specified in this Standard can be found in CCSDS 130.1 G 1. Annex G describes the related mission configuration parameters.
Further provisions and guidance on the application of this standard can be found in the following publications:
-   ECSS-E-ST-50, Communications, which defines the principle characteristics of communication protocols and related services for all communication layers relevant for space communication (physical- to application-layer), and their basic relationship to each other.
-   The handbook ECSS-E-HB-50, Communications guidelines, which provides information about specific implementation characteristics of these protocols in order to support the choice of a certain communications profile for the specific requirements of a space mission.
Users of this present standard are invited to consult these documents before taking decisions on the implementation of the present one.
This standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

Ingénierie spatiale - Liaison de données spatiales - Synchronisation et codage canal de la télémesure

La présente norme établit une implémentation courante des systèmes de codage utilisés dans les canaux de télémesure spatiaux.
Elle décrit plusieurs schémas de codage applicables aux canaux de télémesure spatiaux. Cette norme ne prétend quantifier ni le gain de codage relatif ou les avantages de chaque schéma, ni les exigences de conception applicables aux codeurs ou décodeurs. Certains profils d'application sont toutefois présentés à l'Annexe D. Les données relatives aux performances des schémas de codage spécifiés dans la présente norme sont définies dans la spécification CCSDS 130.1 G 1. L'Annexe G décrit les paramètres de configuration de mission associés.
Les publications suivantes contiennent des dispositions et des préconisations supplémentaires concernant l'application de la présente norme :
•   l'ECSS-E-ST-50, « Communications », qui définit les principes des protocoles de communication et des services connexes pour toutes les couches de communication spatiale (de la couche physique à la couche applicative), et décrit leurs relations de base ;
•   le manuel ECSS-E-HB-50, « Communications guidelines », qui fournit des informations sur les caractéristiques de mise en œuvre de ces protocoles afin d'orienter le choix d'un profil de communication donné compte tenu des exigences particulières d'une mission spatiale.
Les utilisateurs de la présente norme sont invités à consulter ces documents avant de prendre toute décision quant à sa mise en œuvre.
La présente norme peut être adaptée aux caractéristiques et contraintes spécifiques d'un projet spatial, conformément à la norme ECSS-S-ST-00.

Vesoljska tehnika - Vesoljske podatkovne povezave - Telemetrijska sinhronizacija in kodiranje kanalov

Ta standard določa skupno izvedbo vesoljskih telemetričnih sistemov za kodiranje kanalov.
V tem standardu je določenih več vesoljskih telemetričnih shem za kodiranje kanalov. Specifikacija ne poskuša količinsko opredeliti relativnega dobička kodiranja ali prednosti vsake sheme ali zahtev za zasnovo kodirnikov ali dekodirnikov. Vendar so nekateri profili uporabe predstavljeni v dodatku D. Podatki o delovanju za kodirne sheme, določene v tem standardu, je mogoče najti v standardu CCSDS 130.1 G 1. V dodatku G so opisani povezani konfiguracijski parametri misije.
Dodatne določbe in smernice o uporabi tega standarda je mogoče najti v naslednjih publikacijah:
– v standardu ECSS-E-ST-50 (Komunikacije), ki določa glavne značilnosti komunikacijskih protokolov in z njimi povezanih storitev za vse ravni komunikacije, pomembne za vesoljsko komunikacijo (od fizične do aplikacijske ravni), in njihove osnovne medsebojne povezave,
– v priročniku ECSS-E-HB-50 (Komunikacijske smernice), ki zagotavlja informacije o posebnih značilnostih vpeljave teh protokolov za podporo pri izbiri določenega komunikacijskega profila za posebne zahteve vesoljske misije.
Uporabniki obstoječega standarda so vabljeni k ogledu teh dokumentov, preden sprejmejo odločitve o izvajanju trenutnega standarda.
Ta standard se lahko prilagodi posameznim lastnostim in omejitvam vesoljskega projekta v skladu s standardom ECSS-S-ST-00.
