    Talking Astra 3B 23.5°E

    ASTRA 3B 23.5°E

    -este construit pe o platforma EADS Astrium Eurostar-3000 si este prevazut a fi lansat in 24.03.2010 cu o racheta Ariane-5ECA;



    ASTRA 3B arrives for Arianespace’s year-opening launch of 2010
    February 11, 2010


    Image above: The ASTRA 3B satellite was airlifted to French Guiana by an Antonov An-124 cargo jetliner, which landed at Rochambeau International Airport near Cayenne.

    The first of two satellite payloads for Arianespace’s initial Ariane 5 mission of 2010 has arrived in French Guiana.

    SES ASTRA’s ASTRA 3B spacecraft was delivered by an Antonov An-124 cargo jetliner, which landed yesterday at Rochambeau International Airport near the capital city of Cayenne.

    Built by EADS Astrium, ASTRA 3B is a state-of-the-art Ku- and Ka-band spacecraft designed for the distribution of both direct-to-home broadcast services and two-way broadband services across Europe and the Middle East. It will be positioned at the increasingly important 23.5 deg. East orbital position for SES ASTRA.

    ASTRA 3B has a payload power of 10 kW, and can operate at a relay capacity of up to 60 transponders in Ku-band and 4 in Ka-band. It is based on the Eurostar E3000 satellite bus, and is equipped with six mission antennas – four of which are side-mounted and will be deployed in orbit. With a launch mass of 5,470 kilograms, ASTRA 3B has been designed for a nominal lifetime of 15 years.

    Liftoff of the upcoming dual-payload Ariane 5 mission is set for March 24, initiating another busy schedule in which Arianespace has planned a total of seven flights for its heavy-lift workhorse during 2010. In addition, three missions are targeted with the medium-lift Soyuz from its new Spaceport launch facility, and the lightweight Vega vehicle’s maiden flight also could occur before year-end from the Spaceport.

    Beams:

    * Ku-band Europe Beam (predicted)

    * Ku-band S1 Spot Beam (predicted)

    * Ku-band S2 Spot Beam (predicted)

    Launch delay for Arianespace's Ariane 5 mission with the ASTRA 3B and COMSATBw-2 satellite payloads
    March 18, 2010 – Ariane Flight V194

    The flight of Arianespace’s initial Ariane 5 in 2010 has been postponed to allow for certain additional verifications on the launch vehicle.

    This delay is in line with Arianespace’s policy of ensuring the total readiness of its launchers as part of the company’s commitment to quality and reliability.

    The Ariane 5, with its integrated payload of the ASTRA 3B and COMSATBw-2 satellites, is in a safe mode inside the Final Assembly Building at Europe’s Spaceport in French Guiana.

    A new date for the mission will be announced as soon as possible.

    Default astra3B 23,5

    Lansarea de saptmana asta este importanta pentru ca va aduce ceva nou:
    si anume un satelit care are Spot Beams pt EU si Middle East prin reutilizarea frecventelor Eu - ME
    Se vorbeste mult pentru ca sa va vedea cum va functiona o astfel de combinatie va depinde viitorul pt pozitia 19,2 si 28,2 est.
    Mai jos este linkul cu detalii:
    http://www.ses.com/ses/layout/upcomi...et_17Feb10.pdf

    Oricum se pare ca a avut loc o schimbare de strategie 1N va fi la 19,2 si va fi lansat in 2011 iar pentru 28,2 va mai fi lumina pana in 2013....dupa care...nu se stie....

    http://www.ses.com/ses/siteSections/...ches/index.php

    Dar sa vedem cum va merge 3B referitor la spoturile foarte inguste si puternice + reutilizarea frecventelor - aici e tot spilul....

    Dar cum nu toate lansarile reusesc.....putem spera....la un foc de arfificii...

    Talking Ariane 5 makes history with its successful mission to orbit ASTRA 3B and COMSATBw-2

    Ariane 5 makes history with its successful mission to orbit ASTRA 3B and COMSATBw-2
    May 21, 2010 – Ariane Flight V194

    Arianespace delivered another dual-satellite payload into orbit today with a milestone flight that utilized the 50th Ariane 5 launch vehicle.


    Image above: Tonight’s mission with ASTRA 3B and COMSATBw-2 was the 50th launch of an Ariane 5 vehicle.

    Lifting off from the Spaceport in French Guiana, this Ariane 5 ECA version successfully orbited the ASTRA 3B commercial telecommunications satellite for Luxembourg-based SES ASTRA, along with the COMSATBw-2 secure military relay spacecraft for Astrium GmbH on behalf of the German Bundeswehr (armed forces).

    With today’s mission, Arianespace’s workhorse heavy-lift launch vehicle has lofted payloads weighing a combined total of more than 300,000 kg. since its maiden liftoff in 1996.

    During the past 50 flights, Ariane 5s have carried commercial telecommunications satellites; military relay, reconnaissance and early warning spacecraft; Earth observation platforms and meteorological satellites; scientific space probes, experimental and developmental payloads, and the first Automated Transfer Vehicle for servicing of the International Space Station.

    “And this success will continue: after today’s flight Arianespace’s order book still has 34 geostationary orbit satellites to launch – which is a new record – along with six missions with the ATV [Automated Transfer Vehicle] and 17 launches for Soyuz,” said Arianespace Chairman & CEO Jean-Yves Le Gall in post-launch comments at the Spaceport’s mission control center. “Since the start of 2010, Arianespace already has signed seven new contracts, with several others now in advanced negotiations, several others now in advanced negotiations.”

    This evening’s mission with ASTRA 3B and COMSATBw-2 was the 194th flight of an Ariane family launcher since 1979. Payload lift performance for the launch was approximately 9,115 kg. – which included 7,970 kg. for the two satellites, plus the associated integration hardware and the launcher’s SYLDA 5 dual-payload dispenser system.

    The on-time liftoff occurred at the start of a launch window that opened at 7:01 p.m. local time in French Guiana. Ariane 5 provided another high-precision delivery, with the following provisional parameters at the injection of the vehicle’s cryogenic upper stage:
    - Perigee: 248.5 km. for a target of 248.4 km.
    - Apogee: 35,970 km. for a target of 35,969 km.
    - Inclination: 3.00 deg. for a target of 3.00 deg.

    ASTRA 3B was released first into geostationary transfer orbit, being separated from the upper passenger position of Ariane 5’s dual payload “stack” at approximately 27 minutes into the flight. The satellite was produced for SES ASTRA by EADS Astrium, and it had an estimated liftoff mass of 5,470 kg.

    Configured with 60 Ku-band transponders and four Ka-band transponders, ASTRA 3B was the 10th satellite orbited by Arianespace for SES ASTRA, and the 33rd for the SES group – one of the world’s leading providers of satellite transmission capacity. ASTRA 3B will be located at 23.5 degrees East, which is ASTRA's orbital position for delivering Direct-to-Home (DTH) broadcast services to Benelux and Eastern European countries, and this location also will serve public and private satellite communication networks across Europe and the Middle East.

    The COMSATBw-2 lower passenger on Ariane 5 was deployed at approximately 33 min. into the flight. This 2,440-kg. satellite was designed, integrated and tested by Thales Alenia Space on behalf of EADS Astrium – the program’s space segment prime contractor – and it was the 34th military satellite orbited by Arianespace.

    COMSATBw-2 will operate from an orbital position of 13.2 deg. East, providing secure broadband network for uninterrupted communications between the German government, military authorities and armed forces deployed around the world. It is equipped with four SHF-band transponders and five UHF-band transponders, and will join COMSATBw-1 – orbited last October by another Ariane 5.

    Today’s launch had previously been postponed, and Le Gall thanked all who contributed to resolving the technical issues that were encountered. “This flight is the 40th Ariane 5 launch since I joined Arianespace, and more than anyone, I fully appreciate what we owe all of you,” Le Gall added. “I particularly want to thank you for the work performed during the past several weeks, which enabled us to succeed with this superb launch.”

    Le Gall announced that Arianespace’s next Ariane 5 mission is planned for June, with the ARABSAT-5A and COMS-1 satellites.
