    Talking 3.0E o noua pozitie orbitala pentru Eutelsat

    Dupa plasarea la 3.0E a satelitului Eutelsat 3A (fost Chinasat 5C (Sinosat 3)), Eutelsat anunta:

    Eutelsat expands into new orbital position
    July 29th, 2011



    Eutelsat Communications is expanding its commercial response to high-growth video, data, telecom and broadband markets with the opening of business at the 3 East orbital position. To support further long-term expansion, Eutelsat has selected Astrium to build a tri-band satellite, which will increase and diversify its resources for markets in Africa, the Middle East, Central Asia and South America. Called Eutelsat 3B, the satellite will operate in C, Ku and Ka-bands and be launched in early 2014.

    In advance of Eutelsat 3B, resources on a satellite now called Eutelsat 3A were deployed this month to 3 East. This capacity is able to deliver users powerful coverage of Europe and North Africa for services that include GSM backhaul, data networks, IP backbone connectivity and maritime applications.

    To complement Eutelsats capacity portfolio and geographic reach, the Eutelsat 3B satellite will add resources in three frequency bands connected to fixed and steerable antennas for maximum flexibility. With a single platform assembling Ku, C and Ka transponders, users will be able to select the most relevant frequency band for different types of service.

    Up to 51 transponders on Eutelsat 3B will be configured as follows:

    A Ku-band payload of up to 30 transponders will be connected to widebeam footprints over extended Europe and East Africa. A steerable beam will add further flexibility, with coverage possible of South America or African regions. This capacity will address video contribution, corporate networks, data and telecom markets.
    A C-band payload with 12 transponders connected to a pan-African beam will respond to continued high demand for capacity for telecom services.
    A Ka-band payload of nine transponders connected to steerable beams that are in particular expected to cover Africa and South America will meet expanding connectivity requirements for corporate networks and Internet access.

    The Eutelsat 3B satellite will be based on the Astrium Eurostar 3000 platform. Weighing 6 tonnes at launch, the satellite will be designed with 15 year life expectancy. The investment required for this programme is included in Eutelsats capital expenditure outlook for the period 1 July, 2011 to 30 June, 2014.

    Puteai sa deschizi tu un thread cu informatia asta

    Fara mentiunea asta ramineai "GURA-CASCA". Asa ai deveni "GURA-SPARTA"

    Eutelsat Communications raspunde cererii in continua crestere de pe piata de telecomunicatii video si date de banda larga, adaugand o noua pozitie orbitala comerciala la 3 grade Est. Pentru a extinde reteaua sa de sateliti, Eutelsat a selectat firma Astrium pentru a construi un satelit tri-band, care va spori şi diversifica resursele sale pentru pietele din Africa, Orientul Mijlociu, Asia Centrală şi America de Sud. Denumit Eutelsat 3B, satelitul va opera n benzile C, Ku şi Ka şi va fi lansat la nceputul anului 2014.

    Pana la lansarea lui Eutelsat 3B, satelitul denumit Eutelsat 3A a fost plasat deja pe orbita n această lună, tot in pozitia orbitala de la 3 Est. Aceast satelit ofera utilizatorilor o acoperire puternica in Europa si Africa de Nord, fiind folosit, in afara de transmisiile tv, si pentru servicii GSM, reţele de date, conectivitate IP şi aplicaţii maritime.

    Eutelsat 3B insa va adăuga capacitati de transmisie in trei benzi de frecvenţă, transmisii la care utilizatorii vor avea posibilitatea sa se conecteze folosind atat antene fixe, cat si mobile, asigurandu-se astfel flexibilitate maximă. Pe aceeasi platforma satelitara vor putea fi folosite atat transpordere Ku si C, cat şi transpondere Ka, utilizatorii avand posibilitatea sa selecteze banda de frecvenţă cea mai eficienta pentru tipul de servicii la care doresc sa aiba acces.





    Cele 51 de transpondere ale Eutelsat 3B vor fi configurate după cum urmează:

    Pnă la 30 de transpondere in banda Ku vor fi conectate la un widebeam care va emite peste Europa şi Africa de Est. Un fascicul orientabil va adăuga de asemenea o mai mare flexibilitate, cu acoperire posibilă chiar si in America de Sud sau regiunile africane. Aceaste transpordere vor fi folosite pentru tansmisii video, atata de catre retele corporative, cat si cele care vor avea nevoie de transmisii de date, precum si pentru alte transmisii cerute pe pieţele de telecomunicaţii.

    Alte 12 transpondere in banda C vor fi conectate pentru a fi transmise printr-un fascicul pan-african, ca raspuns la cererea in crestere de capacitati de retransmisie pentru serviciile de telecomunicaţii din aceasta zona geografica.

    9 transpordere in banda Ka vor fi conectate la antene de emisie orientabile, care vor acoperi in special Africa şi America de Sud, fiind folosite de marile corporatii din zona, dar si pentru a facilita accesul la internet.
    Eutelsat 3B va fi un satelit bazat pe platforma Eurostar Astrium 3000. Cu o greutate 6 tone la lansare, satelitul va fi proiectat cu o speranta de viata de 15 ani.

    Lista de transpordere active de la 3 grade Est o gasiti aici.
