This would be a big deal (and big advantage) for OneWeb if it works well.

The most overlooked yet critical component for satellite systems to help bridge the digital divide are ground antennas. I have had a team quietly working on this problem for years. 503 versions later we got it. Meet the new $15 fully steerable low power flat panel.

When and why was the first launch reduced from 10 to 4-6 satellites?

Confirmed not Kymeta, wording suggests Tyler's own startup developed it for OneWeb. I'm guessing this is an AESA style?

I wonder if part of the reason the number of satellites has dropped by 33%, but the number of launches is the same is because the satellites have gained weight?
artist, so take opinions expressed above with a well-rendered grain of salt...

According to

https://spacenews.com/oneweb-scales-back-constellation-by-300-satellites/

they're focusing on connecting boats and planes with larger, more powerful terminals first. There's probably more money in that than in connecting the masses.

Focusing on sea and air communications works well with a smaller constellation.

Article also states the satellites are more capable than originally planned. They slightly exceeded the cost per satellite, but with a lower number of higher capacity satellites their first constellation should work fine.

For OneWeb, Arianespace is returning to Baikonur for the first time since a 2013 Soyuz launch for Globalstar. Arianespace, upon winning the OneWeb launch contract in 2015 for 21 Soyuz missions, said then that most of those missions would take place in Baikonur so that the Guiana Space Center could be prioritized for European government missions.
“We are ready for launching in the second part of the year the OneWeb satellites,” Israël said. “The number of launches would depend on the readiness of the satellites.”
Israël said the Soyuz rockets for OneWeb are ready, and that Arianespace will be able to meet OneWeb’s fast-paced cadence of one launch every three weeks so long as OneWeb provides the satellites.
Greg Wyler, OneWeb’s founder, said the company is ready for the first launch and anticipates having around 150 satellites in orbit by the end of the year.
OneWeb plans on starting service with around 300 satellites, and having full, global coverage with 600 satellites.

HERNDON, Va., USA, 14 January 2019 – Airbus Defense and Space Inc. has been awarded a contract from the Defense Advanced Research Projects Agency (DARPA) to develop a satellite bus in support of the Blackjack program.

Quote
“Airbus has previously co-invested hundreds of millions of dollars in high-rate manufacturing technology and supply chain logistics to build large constellations of small satellites,” said Tim Deaver, Director of US Space Programs at Airbus Defense and Space, Inc. “Airbus is committed to growing manufacturing capability in the US and our government customers can leverage this commercial capability to develop low-earth orbit constellations to complement large existing systems.”

This contract positions Airbus Defense and Space, Inc., of Herndon, Va., and its strategic joint venture partner, OneWeb Satellites, of Exploration Park, Fl., as the ideal service providers for Blackjack.

Sounds like it will use the OneWeb manufacturing facility in Florida, hence their inclusion.

The 32-sat payload adapter.  I guess it wasn't worth designing a different one for the first flight.

"Airbus OneWeb Satellites"



Not sure how much more cost effective it is to have a robot watched by an engineer put a box on the side of a satellites rather than picking it up and placing it by hand. But still cool.

I'm kind of surprised there's nothing yet on this thread about OneWeb's successful launch of their first 6 satellites. Note that unlike Telesat and SpaceX, these are full-functionality satellites using their planned flight design, not just subscale proof of concept pathfinder satellites. The main difference between these and their operational satellites is just that they were built on the Airbus line in Toulouse instead of at the OWS Titusville plant where the ~650 operational satellites will be built.

I was a little skeptical of the approach--they could've had something on orbit a lot sooner had they gone with a simplified pathfinder, but it'll be interesting to see how these first satellites perform, and what this means for them going forward.

I was just surprised at how little there was about something that may be a pretty big deal.

Remember, there's a launch thread on this, Jon:

https://forum.nasaspaceflight.com/index.php?topic=47158.0

Thanks Chris! I tried looking for that one, but hadn't been able to find it.

I just would've thought there'd be some commentary on the main thread about what this means for OneWeb and the race to develop megaconstellations. I was just surprised how quiet it was on here, given the fact that there are others who post on here on a regular basis.

Followup, the startup has somewhat surfaced as Wafer LLC.

https://wafer.tv/

https://spacenews.com/wyler-claims-breakthrough-in-low-cost-antenna-for-oneweb-other-satellite-systems/

The spacenews article comments make an interesting point about possible patent collisions between Wafer/Wavebender and Kymeta and Alcan.

Additionally, there is the oddity that the main company is registered as a domestic LLC in Massachusetts, but a branch is registered as a foreign LCC in Florida. Is this to facilitate foreign investment and to provide an ITAR barrier?
