Dec. 24, 2015- Inmarsat-6 satellites dual mission will augment both L-band and Ka-band Global Xpress services - New all-electric satellites order reinforces Airbus Defence and Space’s world leadership in high power electric satellites - Contract valued in the region of $600M (€550M)Airbus Defence and Space, the world’s second largest space company, has been awarded a contract by Inmarsat, the leading provider of global mobile satellite communications services, to design and develop the first two Inmarsat-6 (I-6) mobile communications satellites, creating the most versatile mobile services satellites in its fleet.The two I-6 satellites will be based on Airbus Defence and Space’s ultra-reliable Eurostar platform in its E3000e variant, which exclusively uses electric propulsion for orbit raising. The satellites will take advantage of the reduction in mass that this electric propulsion technology enables for a dual payload mission, with an exceptionally large next generation digitally processed payload.“We are delighted to have been selected by Inmarsat to build their latest and most sophisticated satellites”, said François Auque, Head of Space Systems. “This mission for our next generation digitally processed payload represents a step change in capability and capacity. The spacecraft will complement and enhance the L-band services offered by the Airbus Defence and Space-built Inmarsat-4 and Alphasat satellites, and embark a Ka-band mission to augment Inmarsat’s globally available high-speed broadband service - Global Xpress.”“The Inmarsat-6 constellation confirms our continued commitment to delivering advanced L-band services for decades to come,” said Rupert Pearce, CEO of Inmarsat. “The new satellites will provide significantly greater L-band capacity and will be capable of supporting a new generation of more advanced L-band services.”“The Ka-band co-payload adds depth to the breadth of the unique capabilities of our Global Xpress (GX) constellation, which now spans the world.”I-6 F1 and F2 will carry a large 9m aperture L-band antenna and nine multibeam Ka-band antennas, and feature a high level of flexibility and connectivity. A new generation modular digital processor will provide full routing flexibility over up to 8000 channels and dynamic power allocation to over 200 spot beams in L-band. Ka-band spot beams will be steerable over the full Earth disk, with flexible channel to beam allocation.The first satellite (I-6 F1) is scheduled for launch in 2020 and its electric propulsion system will enable it to reach geostationary orbit in four to six months, depending on the type of launcher used. It has been designed to remain in service in orbit for more than 15 years.I-6 F1 is the 50th Eurostar E3000 satellite and the 12th Inmarsat satellite ordered from Airbus Defence and Space. This new contract reinforces Airbus Defence and Space’s position as the world’s number one in electric propulsion satellites, with six full electric high-capacity telecommunications satellites already sold. The investments made by the company in future platform and payload technologies are supported by the European Space Agency and national agencies, in particular the UK Space Agency and CNES.
July 2, 2014...Finally, Inmarsat and SpaceX have agreed terms for a third launch vehicle opportunity that can be used for other future missions, including potentially for the launch of an Inmarsat-6 generation satellite. The Inmarsat-6 satellites have not yet been designed or ordered and a first launch is targeted only towards the end of the decade.
Pearce said Inmarsat could launch Inmarsat-6B on a Falcon Heavy rocket, since the company still has an unused launch option with SpaceX, but hasn’t committed the satellite to that vehicle.
Isn't this supposed to launch on Falcon Heavy?From 2019:QuotePearce said Inmarsat could launch Inmarsat-6B on a Falcon Heavy rocket, since the company still has an unused launch option with SpaceX, but hasn’t committed the satellite to that vehicle.https://spacenews.com/inmarsat-to-place-gx-flex-next-gen-satellite-system-order-this-year/
It solely depends on potential secondary payload slot being sold as reduces cost slightly for primary payload.

I-6 F2 commences thermal vacuum testing07 Apr 2022Inmarsat's latest geostationary satellite, I-6 F2, makes its way towards thermal vacuum testing.large satellite entering a tunnel chamber with two technicians in lab coatsThe satellite is made by Airbus Defence and Space in Stevenage and Portsmouth in the UK prior to final assembly and testing in Toulouse, France. I-6 F2 will be tested thoroughly for several months. The diameter of the Airbus testing chamber pictured is 10 metres, about as high as a four-storey building, and it is capable of creating temperature extremes from -173 Celsius to 120 Celsius (-279 to 248 Fahrenheit) including rapid cycling and long-duration (30-day) temperature plateaus to simulate the harsh conditions of space.I-6 F2, almost as large as a double-decker bus and with a solar array 'wingspan' larger than a Boeing 767, will be launched in Q1 2023 by SpaceX from Cape Canaveral, Florida, USA. It follows its 'twin' I-6 F1, which was launched by MHI in Japan in December 2021.The I-6 series of satellites are the most sophisticated commercial communications satellites ever and are operated from 36,000km (22,500 miles) above the Earth at Inmarsat’s control centre in London, UK.(Image credit: Inmarsat / Airbus Defence and Space.)
Win a trip of a lifetime to watch Inmarsat’s largest communications satellite launch onboard a SpaceX rocket from Cape Canaveral in America.Have you ever wondered what it feels like to watch a live rocket launch, hear the incredible roar of the engines and feel the ground shake as it lifts off into space? Well now you have a chance to find out!Inmarsat is excited to team up with the Scouts to run a competition to win a once-in-a-lifetime trip to Cape Canaveral, Florida in America to watch the launch of its double-decker bus-sized communication satellite.The satellite, named I-6 F2, will take flight on a SpaceX rocket early next year, with Scouts’ Ambassador and world-famous astronaut Tim Peake, judging your entries. All you have to do to be in with a chance of winning one of two places for this amazing five-day trip in February 2023, is answer the following question:
At 100 sqm when unfurled, the L-band reflector on our #I6F2 🛰️ means business! It will help power twice the capacity and the fastest speeds for our ELERA network. The satellite is being rigorously tested with @AirbusDefence, ahead of launch in 2023: https://www.inmarsat.com/en/about/technology/satellites/i-6.html
A Falcon 9 will launch the Inmarsat 6 F2 satellite from pad 40 on mid-late February.
Ka-band pallet integration is complete on our #I6F2 @AirbusDefence 🛰️. These 6 large reflectors will deliver Global Xpress high-speed broadband services over the Atlantic Ocean, along with 20 steerable spot beams. Look out for launch details coming soon: https://bit.ly/3P9DlPY
Is Inmarsat I-6 F2 correct or is that repeating the Inmarsat ( https://en.wikipedia.org/wiki/RAS_syndrome )?https://www.launchphotography.com/Launch_Viewing_Guide.html calls it "Inmarsat 6 F2"
Inmarsat’s latest I-6 F2 satellite will travel from Toulouse, France, to SpaceX’s Cape Canaveral launchpad in January.Inmarsat, the world leader in global, mobile satellite communications, has agreed with Airbus Defence and Space to deliver its I-6 F2 satellite via a series of ‘stepping stones’ across the Atlantic using Airbus’ A300-600ST (Super Transporter). The aircraft is better known as Beluga, thanks to its striking similarity with the species of whale.The journey will see the satellite leave its testing facility in Toulouse and make several stops for refuelling before reaching the Kennedy Space Centre in Florida. Spacecraft experts will then have approximately three weeks for final testing and integration of spacecraft with the rocket before I-6 F2 launches on a SpaceX Falcon 9 in February.
One of the last tasks at the @AirbusSpace facility in Toulouse is to load #I6F2 🛰️ with over 1,000 kg of Xenon gas, a non-combustible liquid air propellant which will power the satellite’s all-electric propulsion system for orbit raising: https://bit.ly/3GC0k2e
First stage landing should be ASDS, yes?
As #I6F2 gets ready to bid adieu to Toulouse & travel to the Kennedy Space Center in an Airbus Beluga, we’d like to say a huge thank you to all the Inmarsat & @AirbusSpace engineers who have worked tirelessly assembling & testing our complex spacecraft. 🛰️ https://bit.ly/3GYSorZ

It will be the ninth Eurostar in orbit that is equipped with electric propulsion for orbit raising, reinforcing Airbus’ position as the world leader in electric propulsion.François Gaullier, Head of Telecommunications & Navigation Systems at Airbus, said: “I-6 F2, with its sophisticated digitally processed payload, will join Inmarsat-6 F1 (I-6 F1) in orbit giving Inmarsat even more flexibility, capability and capacity. This is the 10th geo-telecommunications satellite we have built for our long-term customer Inmarsat, a leading provider of global mobile satellite communication services, and with I-6 F1 the satellites will enable a step change in the capabilities and capacity for their ELERA services, and deliver significant additional capacity for their Global Xpress network.”I-6 F1 and I-6 F2 each feature a large 9m aperture L-band antenna and six multi-beam Ka-band antennas, giving a high level of flexibility and connectivity. They also carry new generation modular digital processors to provide full routing flexibility over up to 8000 channels and dynamic power allocation to over 200 spot beams in L-band, per spacecraft. The Ka-band spot beams are steerable over the full Earth disk, with flexible channel to beam allocation.The satellites will enable Inmarsat to further enhance its world-leading ELERA (L-band) and Global Xpress (Ka-band) networks respectively, for customers across land, sea, and air. They are also the next step in the company's plans for the world’s first multi-dimensional network, Inmarsat ORCHESTRA. The ‘network of networks’ will build on Inmarsat’s existing space-based capabilities to provide a transformational growth in capacity and new features for customers into the 2030s and beyond.Investments made by Airbus in platform and payload technologies used on I-6 are supported by the European Space Agency and national agencies, in particular the UK Space Agency and CNES, France’s National Centre for Space Studies. I-6 F2 has a launch mass of 5.5 tons, spacecraft power of 21 kW and a design life of more than 15 years.The first Airbus built Inmarsat-6 (I-6 F1) satellite was successfully launched in December 2021. It reached its geostationary testing location in summer 2022 and is scheduled to enter service in early 2023. I-6 F2 is set to follow after its successful launch and enter service in early 2024.Airbus’ geostationary telecommunications satellites have clocked up more than 1300 years of successful operation and are in service or being built for all of the world’s leading geostationary satellite operators.@AirbusSpace @InmarsatGlobal #Connectivity #SpaceMatters #NextSpace #I6F2

Inmarsat confirms successful launch of world’s most advanced satellite18 Feb 2023CORPORATE PRESS RELEASE SATELLITESSpaceX successfully launched Inmarsat’s latest I-6 F2 satellite successfully launched last night from launch pad SLC-40 at Cape Canaveral Space Force Station in Florida.Inmarsat, a world leader in global, mobile satellite communications, has announced the successful launch of its latest I-6 F2 spacecraft from the Cape Canaveral Space Force Station aboard a flight proven SpaceX Falcon 9 rocket.The launch saw I-6 F2 lift off from Cape Canaveral, Florida, reaching a top speed of almost 40,000km/h as it left Earth above central Africa. The satellite will now spend several months travelling to its geostationary orbit, 36,000km above the Equator, using its onboard electric propulsion system. It is scheduled to connect its first customers in 2024, following rigorous in-orbit technical testing. I-6 F2 follows its ‘twin’, I-6 F1, which launched from Japan in late 2021. They are the most sophisticated commercial communications satellites ever and will provide a revolutionary upgrade in Inmarsat’s global coverage services for at least the next 15 years. I-6 F1 is scheduled to connect its first customers later this year.The new I-6 satellites add further capabilities to Inmarsat’s ORCHESTRA communications network; a unique, global, multi-dimensional, dynamic mesh network that will redefine connectivity at scale with the highest capacity for mobility worldwide. ORCHESTRA enables Inmarsat’s partners and customers to keep pace with their growing data demands and enables them to empower emerging technologies in the future, like autonomous vehicles or flying taxis. The launch was seen live by Scouts Simon Shemetilo, from London, and Craig Alexander, from Reading, who had a VIP viewing experience to the event. The two were chosen by Astronaut Tim Peake after Scouts from all over the UK entered a competition hosted by Inmarsat and the association. Simon and Craig were judged as submitting the best entries for how satellites can improve life on Earth in the future.Rajeev Suri, CEO, Inmarsat, said “I want to extend my profound thanks and appreciation to our dedicated employees and partners who have made this launch a reality. Our I-6 programme has been six years in the making. Last night’s launch marked another milestone as we revolutionise global communications at scale.”“Of course, this is not the end. Along with the I-6s, we will add five more advanced spacecraft to our fleet by 2025 as part of our fully funded technology roadmap. That will allow us to continue to meet our customers’ needs into the 2030s and beyond, while enabling new technologies for a smarter, more connected Earth.”

Still no independent confirmation (via SpaceForce TLE data) of successful Inmarsat 6F2 launch after more than 48 hours
was it a direct inject or is it going to be doing gradual orbit raising over a long period? The latter creates a lot of challenges for their Elset 1 process
No, direct to GTO - not sure if was a bit subsync or supersync though. I have the impression supersync is difficult for them

IMO, "supersynchronous transfer orbit" may refer to a GTO with an apogee of 40,000+ kilometers. Anything between the 35,786-40,000 range is standard GTO.Again, it's my opinion.

Anything between the 35,786-40,000 range is standard GTO.Again, it's my opinion.Am I correct in understanding that apogee is measured from the center of earth?If so GEO apogee is 42,164 km. Steven Pietrobon estimated an apogee of 42,529 so just barely supersync?Edit: Steven Pietrobon wrote apogee, but he could have meant to write altitude. He does refer to altitude later in the same post.
I never use distance from the centre of the Earth for the apogee and perigee! That would be too confusing. I calculate my altitudes by subtracting 6378.165 km (Earth's equatorial radius) from the distance to the centre of the Earth.

For Earth orbits I usually see it called semi-major axis for the (apogee) distance from the center of the Earth.

I calculate my altitudes by subtracting 6378.165 km (Earth's equatorial radius) from the distance to the centre of the Earth.Me neither.There are times to use the altitude, and other times to use the radius.There is a value of each for perigee and apogee around Earth, or periapsis and apoapsis in general.In my calculations, they are commonly labled alt-a and alt_p vs r_a and r_p.It's pretty clear which one to use for any given calculation.It's not so obvious which is being used in conversation for orbits around GEO, so one has to be explicit when it matters.That said, was the launch of I6-F2 to a few hundred kilometers above GEO or 7,000 km above GEO?
Today before sunrise the Falcon 9 booster B1077 returned to Port Canaveral on the autonomous drone ship “Just Read the Instructions”. After sunset the SpaceX support ship “Shannon” left the Port presumably supporting the upcoming Crew 6 launch on February 27. @SpaceOffshore
It’s all systems go for #I6F2 - L-band 9m wide antenna successful deployed and ‘bloomed’ - 47m wide solar array panels successfully deployed - Electric Orbit Raising phase to GEO orbit has commencedFind out more about our special I-6 satellites: https://bit.ly/3mulnNY

The satellite is currently engaged in electrically propelled orbit-raising maneuvers en route to the 28º W.L. orbital location, with arrival anticipated on October 9, 2023.
A second Viasat communications satellite is malfunctioning in orbit, this time from the fleet of recently acquired U.K.-based Inmarsat, the company said on Thursday.The I6 F2 satellite, which Inmarsat launched in February, suffered a failure with its power system while climbing in orbit to where it planned to operate as a backup.Airbus manufactured the satellite and is, alongside Viasat, assessing whether the satellite can be recovered for use.A person familiar with the matter told CNBC that the odds of the satellite recovering are low....
Viasat’s Inmarsat-6 F2 satellite suffers power failure on way to orbital position; total loss fearedwritten by Peter B. de Selding August 24, 2023TUPPER LAKE, NY — Viasat's Inmarsat-6 F2 satellite, launched in February, has suffered a power-system failure that may end its useful life and result in a $350 million insurance claim, industry officials said.The event, which would be the first major satellite failure in London-based Inmarsat’s 40-plus-year history, would also be a rare stain on the reputation of the satellite’s prime contractor, Airbus Defence and Space, which has used its reliability record as a point of sale.
...The Company confirms that it has insurance coverage of $348 million in place for the I6 F2 satellite and will finalize its claim before the end of the year....
Viasat Shareholder Letter: Q2 Fiscal Year 2024 Financial ResultsQuoteOur satellite manufacturer and antenna supplier have made significant progress in determining the root cause of the ViaSat-3 F1 deployment anomaly. The rest of the spacecraft and payload are performing nominally, or better. Detailed analyses of the antenna status indicate we can obtain sufficient bandwidth, speed and coverage, combined with our existing and planned fleet, and partner space resources, to support our growing global mobility business. Even at less than 10% of its original design capacity, the design of ViaSat-3 F1 allows its available capacity to be allocated flexibly across an expanded coverage area. The anomaly does significantly impact the U.S. residential fixed broadband business, which will remain a smaller portion of current revenue until new capacity can be allocated. Eventually ViaSat-3 F2 or ViaSat-3 F3 will replace ViaSat-3 F1 over the Americas given the opportunities in that market, and the combination of ViaSat-3 F1 with the space assets available in other markets. The ViaSat-3 F3 antennas use a different design from a different supplier. It has a launch contract for the fourth quarter of calendar 2024 (about 1 year away) and is not affected by the anomaly. We expect the ViaSat-3 F1 anomaly investigation will conclude next week and will include recommended corrective actions for ViaSat-3 F2. The details of the corrective actions will drive the launch schedule. We expect to file insurance claims for both ViaSat-3 F1 and Inmarsat-6 F2 before the end of calendar 2023.

Submitted insurance claims for Inmarsat-6 F2 and ViaSat-3 F1 for $349 million and $421 million, respectively. The claims process is progressing as expected, with initial payments received subsequent to quarter end.
