Re: l'avenir d'Eutelsat 5W

Messagepar krystof » 13 Jan 2020 21:56

Le champs du cygne pour 5WA, son contrôle de poste nord/sud est off depuis décembre. Donc son orbite va s'incliner progressivement pour laisser la place à 5WB, pas d'impact sur les réceptions grand public mais cela commence a être visible sur les paraboles de grand diamètres (240 mini).


Malgres le problème de déploiement du panneau solaire sud de 5WB, il pourra assurer de manière pérenne un certain nombres de services (cela sous entends donc pas tous), pour l'instant cette migration partielle est planifiée dans la nuit du 20 au 21 janvier 2020, suivront quelques ajustements (PIRE, plan de référence,...), prévoir a terme un écart de polarisation par rapport à 5WA d'~3.5°(en principe invisible sur les paraboles grand public dont la contre-polar est correctement ajustée).

The swan fields for 5WA, its north / south substation control has been off since December. So its orbit will gradually tilt to leave room for 5WB, no impact on receptions for the general public, but it is starting to be visible on large diameter dishes (240 mini).

Despite the problem of deploying the 5WB south solar panel, it will be able to provide a certain number of services on a long-term basis (this does not therefore mean all), for the moment this partial migration is planned for the night of 20 to 21 January 2020 , will follow some adjustments (EIRP, reference plane, ...), in the long term foresee a polarization difference compared to 5WA of ~ 3.5 ° (in principle invisible on parabolas for the general public whose counter-polar is correctly adjusted) .

Eutelsat 5West B is alive,
A new plan will be required to support 5 west as Eutelsat 5West B cannot cover all transponders so a back up satellite may be needed here @ 5 west to work with the damaged 5 West B ?
Unless as now looks possible some Italian TV migrates to another satellite.

Not far to go now https://www.n2yo.com/?s=44624
When Eutelsat 5West B arrives @ 5 west tracking will show that it has passed 5 west in the next few days this is normal & will corrected later.

Default Eutelsat 5 West B Ku band satellite starting 20 to 21 January 2020

There are 3 Ku band beams for Eutelsat 5 West B transmissions are due to start from 5° west next week,

This will allow Eutelsat 5 West A to move from here to another place this will also be the end of C band transmissions from 5° west,

It has been established in this thread that the main transponders will be for Fransat & French Multi-Streams & they will probably be on the new Transalpine beam,

There is an Algerian spot beam that may be used there has been no Algerian TV from 5° west for a few years now & with the reduced capacity of 5 West B this may not be possible.

the algerians have their own satellite at 24,8* with similar beam so propably you are right 5W wont be needed

Do you know, what satellite dish size will be necessary for trans-alpine beam in north moravia-silesia? I think that 100 cm should be enough.

Until the new satellite starts @ 5 west next week it is just guess work a 100cm may be OK on the transalpine beam but if they use the European beam then a 100cm will be no problem in your location.

I know that European beam is no problem in my location, it's the same as Wide beam on old E5WA, but I think that french multistream will use Trans-alpine beam and European beam could be useful only for dish allign, if it will be activated. There is also a problem with solar array. Do you think that multistream muxes will be crypted?
