Skynet 5A, 5B, 5C, 5D



Skynet 5A [Astrium]

Skynet 5 is the programme to update the UK's military satellite communications capability for the British Ministry of Defence. The Skynet 5 system will provide the next generation of secure global military satellite communications system, initially through the transfer of ownership, operation and enhancement of the existing Skynet 4 infrastructure and then by incorporating new Skynet 5 satellites and associated ground segment from the middle of this decade. The programme will be delivered in the form of a service provision contract.

Under contract to Paradigm Secure Communications, sel ected in February 2002 as preferred bidder for the Skynet 5 secure global military satellite communications programme, Astrium is responsible for the replacement of the existing Skynet 4 ground and space assets (for which the company is prime contractor) by a new, integrated Skynet 5 system. Astrium has supported the Skynet 5 programme fr om its outset, including various concept studies carried out over the past five years. The contract for two satellites was awarded in October 2003. In December 2005 Paradigm deceided not to insure the first two satellites, but to procure a third one as a spare, as well as a option to a fourth satellite.

Astrium ready to ship Skynet 5D for December launch
By:   Dan Thisdell London
09:50 12 Nov 2012
 

One of the UK Ministry of Defence's most radical private sector supply contracts is set to mark its halfway point with a dramatic increase in capability, as Astrium Services starts the final push towards a 19 December launch of the fourth satellite in its Skynet 5 secure communications constellation.
SKynet 5D Astrium

By adding another layer of redundancy to the existing three satellites - the first of which was launched in 2002 - the new 5D spacecraft, designed for a 12-year service life, has allowed the UK MoD to extend until 2022 its 10-year old Skynet 5 X-band and UHF contract with Astrium Services, which formerly ran the scheme as Paradigm.

The new spacecraft will also extend the geographic reach of the service. In addition, as Astrium Services has also acquired the payload of the Anik G1 satellite - set for launch in early 2013 - within the next few months Skynet's provision of X-band services will stretch fr om 178˚W to 135˚E, leaving just a narrow strip of the Pacific out of range. X-band is used for communication beyond theatre and has the advantage of being highly secure.

Speaking in Toulouse on 6 November, wh ere final checks had been completed before Skynet 5D was to be packed for shipping to the European spaceport in Kourou, French Guiana, for integration with its Ariane 5 rocket, Astrium Services executive director for government communications Simon Kershaw said the new spacecraft would provide also at least 11 new NATO-compliant UHF channels for tactical communications by UK and other forces which buy Skynet communications support. UHF, he added, is a "rare commodity" for troops in the field.

In addition to tactical and out-of-theatre communications, Skynet provides personal mobile phone and internet access for troops in Afghanistan and other theatres.

In addition to the UK, customers have included NATO, the US Department of Defense and the armed forces of Australia, Canada, the Czech Republic, France, Germany, the Netherlands, Poland, Portugal and Slovenia.

Astrium has two major Skynet ground stations in addition to its satellite and connections control centre in Corsham, Wiltshire, and provides a number of mobile ground stations for forward deployment. Agreement with the MoD is "imminent", adds Kershaw, for the development of a less capable but more-easily deployable ground station which could also find its way on to ships.

ЦитатаArianespace's launcher family cadence: Ariane 5 joins Soyuz in mission preparations at the Spaceport

November 27, 2012 - Ariane Flight VA211

The Spaceport is once again handling parallel campaigns with two different members of the Arianespace launcher family, as a heavy-lift Ariane 5 has moved to the Final Assembly Building to be readied for its December 19 flight, while a medium-lift Soyuz is now complete at a separate complex in French Guiana for a nighttime launch this Friday.

Arianespace's mission with Ariane 5 is to orbit the Mexsat Bicentenario telecommunications satellite for Mexico and the European Skynet 5D military relay platform. The launch is designated Flight VA211 in the company's numbering system, signifying the upcoming 211th liftoff of an Ariane family vehicle from the Spaceport.

With the transfer of Flight VA211's Ariane 5 to the Final Assembly Building within the Spaceport's ELA-3 launch complex today, it will be ready to receive the dual payload for Arianespace's seventh flight with the heavy-lift workhorse vehicle in 2012.

In separate activity across the Spaceport in its northwestern sector, the Soyuz for Arianespace's next medium-lift mission has been equipped with its Pléiades 1B observation satellite passenger at the ELS launch complex. This is Flight VS04, notating Soyuz' fourth mission at the Spaceport since it entered service at the facility in October 2011 - and the second liftoff in 2012 of the Russian-built vehicle from French Guiana.

ЦитатаPayload integration is completed for Arianespace's year-ending Ariane 5 mission with Skynet 5D and Mexsat Bicentenario

October 14, 2012 - Ariane Flight VA211

The Skynet 5D satellite has joined its Mexsat Bicentenario co-passenger on Ariane 5, marking a new milestone in preparations for Arianespace's seventh and final heavy-lift flight of 2012 from the Spaceport in French Guiana - scheduled for December 19.

Encapsulated in an ogive-shaped payload fairing, Skynet 5D was lowered into place on Tuesday over Mexsat Bicentenario - which had been installed atop Ariane 5's cryogenic core stage during activity the previous day inside the Spaceport's launch vehicle Final Assembly Building.

Skynet 5D is riding as the upper passenger in Ariane 5's payload "stack," to be deployed first in the launch sequence. This is the fourth satellite in the Skynet 5 series built by Astrium, which is the prime contractor for the British military satellite program - operated as a Private Finance Initiative with the United Kingdom's Ministry of Defence.

The Astrium Services business of Astrium operates the Skynet military satellite constellation and the ground network for all beyond-line-of-sight communications to the U.K. Ministry of Defence and the Cabinet Office. Astrium Services also provides Skynet-based communication services to other forces around the world, including the United States, Portugal and Australia.

The Skynet 5D relay platform is expected to reinforce and extend the operational services provided by the three Skynet 5 satellites already in orbit. It will be located over the Middle East - at a 53 deg. East orbital slot.  The first three Skynet 5 satellites also were launched by Arianespace on Ariane 5 vehicles.

Larger fuel tanks on this latest Skynet spacecraft will enable it to be repositioned more frequently to meet operational needs. Skynet 5D will extend the total commercially-owned X-band (Super High Frequency) to over 2 GHz of high powered beams across the globe.  To provide additional UHF capacity on Skynet 5D for military and government customers worldwide, Astrium Services earlier this year signed a multi-million dollar contract with Harris CapRock.

The Mexsat Bicentenario passenger to be launched December 19 with Skynet 5D on Ariane 5 is based on Orbital Sciences Corporation's GEOStar-2 spacecraft platform. It will provide communications services to Mexico and its surrounding waters from the 114.9 deg. West Longitude orbital slot and has a design mission lifetime of 15 years.

Orbital was sel ected by Boeing to provide the Fixed Satellite Services (FSS) segment of the Mexsat satellite system for the Federal Government of Mexico, with this contribution consisting of the Mexsat Bicentenario spacecraft and the FSS ground segment - including satellite command and control ground equipment and software, as well as training and operational documentation.

The year-ending Ariane 5 mission with Mexsat Bicentenario and Skynet 5D is designated Flight VA211 in Arianespace's numbering system, signifying the 211th liftoff for an Ariane family vehicle fr om the Spaceport.


The payload fairing containing Skynet 5D is readied in the Spaceport's Ariane 5 Final Assembly Building for installation atop its launcher.

ЦитатаOn a theme of "10," Arianespace completes another year of launch successes

December 19, 2012 - Ariane Flight VA211

Arianespace's Ariane 5 flight with the Skynet 5D and Mexsat Bicentenario satellite passengers today wrapped up another busy year of company launch activity, with its successes highlighted by the theme of "10."

During 2012, the Arianespace launcher family performed a total of 10 missions from the Spaceport in French Guiana, led by the heavy-lift Ariane 5 with its 10-metric-ton payload lift performance - which has logged 53 consecutive successes during the past 10 years.

Arianespace's mission cadence in 2012 was called "remarkable" by Chairman & CEO Jean-Yves Le Gall.

"It confirms the interest, effectiveness and availability of our launcher product line - which enables us to launch all satellites, for all of our customers, to all orbits," he said during comments after today's flight.  "In addition, 2012 also marked a yearly record in terms of payload mass placed into orbit, since - for the first time - we have reached a total of nearly 75 tons, of which 20 tons was for the Edoardo Amaldi Automated Transfer Vehicle!"

The Arianespace launcher family missions performed from French Guiana this year were composed of seven heavy-lift Ariane 5 flights, two with the medium-lift Soyuz, and the lightweight Vega's inaugural launch.

Le Gall paid homage to all of the players who contributed to the 2012 successes, including the European Space Agency, France's CNES space agency, the Spaceport teams in French Guiana, Europe's industrial network for Ariane and Vega, the Russian companies for Soyuz, and the team at Arianespace.

Along with the Spaceport's launch successes was an additional Soyuz mission - performed from the Baikonur Cosmodrome in Kazakhstan by Arianespace's Starsem affiliate.

"And I can add that if you liked 2012, you will love 2013!" Le Gall stated in his concluding remarks.

For tonight's mission, Ariane 5 deployed its Skynet 5D payload first, followed by Mexsat Bicentenario during a 36-minute flight profile that came after an on-time departure from French Guiana at 6:49 p.m.

Underscoring Ariane 5's continued high level of accuracy, the launch vehicle's estimated orbital parameters at injection of its cryogenic upper stage were:
- Perigee: 249.8 km. for a target of 249.7 km.
- Apogee: 35,981 km. for a target of 35,972 km.
- Inclination: 1.99 deg. for a target of 2.00 deg.

Skynet 5D was orbited for Astrium Services as the fourth in the British military's Skynet 5 satellite system, and weighed approximately 4,800 kg. at launch.  This spacecraft is designed to reinforce and extend the operational services provided by the three other Skynet 5 satellites - all orbited by Ariane 5 - and will be located over the Middle East at a 53 deg. East orbital slot.  The Skynet program is operated as a Private Finance Initiative with the United Kingdom's Ministry of Defence.

Mexsat Bicentenario weighed an estimated 3,000 kg. for liftoff, and is based on Orbital Sciences Corporation's GEOStar-2 platform.  It is to provide communications services to Mexico and its surrounding waters from the 114.9 deg. West Longitude orbital slot. Orbital was designated by Boeing to provide the Fixed Satellite Services (FSS) segment of the Mexsat satellite system for the Federal Government of Mexico.

As Arianespace celebrated a 2012 to remember in terms of its launch activity, the company already is looking to next year's activity. Preparations are well advanced for a Starsem Soyuz mission from Baikonur Cosmodrome with six Globalstar constellation spacecraft at the start of February, as well as an Ariane 5 launch at the Spaceport - which is to orbit the Amazonas 3 and Azerspace/Africasat-1 telecommunications satellites during the first week in February.


The year-ending Ariane 5 mission of 2012 was a dual-payload flight performed from the Spaceport's ELA-3 launch complex in French Guiana.


The Skynet 5D and Mexsat Bicentenario satellites were lofted on the heavy-lift Ariane 5 launcher's 53 consecutive successful mission.
