EchoStar puts faith in third nanosatellite for global S-band plan

Published

on

TAMPA, Fla. — EchoStar hopes the third time will be a charm for the U.S. satellite operator racing to secure global non-geostationary S-band rights this summer.

The company plans to lock down these spectrum rights ahead of an Aug. 10 deadline with a nanosatellite launching before the end of June, EchoStar Satellite Services president Anders Johnson told SpaceNews in an interview.

Its last two nanosatellites suffered post-launch propulsion system failures that prevented them from reaching an orbit where EchoStar must provide services before the August deadline to keep the license.

EchoStar previously had until the beginning of April to secure the license, but got an extension from the International Telecommunication Union (ITU) to make its third attempt.

Tyvak Nano-Satellite Systems built all three nanosatellites. 

Securing the license by bringing the satellite into use will in essence extend EchoStar’s S-band footprint beyond Europe and parts of Africa and the Middle East, where it currently offers voice and data mobile satellite services (MSS) from geostationary orbit.

“Once we have those rights in use, that then gives us all of the raw materials to hopefully be able to fully pursue the development of a global business in the band,” Johnson said.

S-band spectrum is unique because it is dually licensed worldwide at the ITU level for terrestrial and satellite use, he added.

However, it will take time to develop and prove capabilities that draw on combined technologies. 

EchoStar plans to integrate its mobile satellite service capabilities with a complementary ground component in the future.

Its sister company, U.S. satellite TV provider Dish Network, is building out a terrestrial wireless network partly with S-band spectrum it acquired nearly a decade ago for North America.

Years in the making

Billionaire Charlie Ergen controls Dish Network and EchoStar. While Dish Network focuses on the U.S. market, EchoStar embarked on its international S-band strategy in 2013 after buying Solaris, an Irish company that was struggling to find a market for the frequencies covering Europe.

Solaris changed its name to EchoStar Mobile Limited (EML), and now provides connectivity services in and around Europe with its EchoStar-21 satellite and a partly operational payload on Eutelsat-10A.

British satellite operator Inmarsat also has an S-band license for the region, using the spectrum for its hybrid satellite and cellular European Aviation Network (EAN). 

Inmarsat’s competitors have launched legal action over how EAN is using S-band, arguing that its heavy ground network use conflicts with the license’s intent.

After buying Solaris, Johnson said EchoStar obtained S-band licenses in other places, including Mexico.

In late 2019, it acquired Canadian startup Helios Wire, which was developing a business to connect satellites with Internet of Things devices. 

That acquisition gives EchoStar worldwide S-band rights in low Earth orbit (LEO) — if it can launch and operate its upcoming satellite in time.

Helios Wire’s regulatory filings give EchoStar priority rights over “pretty much everyone else” that filed for similar frequencies, according to Johnson.

However, he added “we’re also realistic in our expectation as to exactly what that global footprint looks like, because in certain countries the S-band has already been licensed for — and deployed — terrestrially.”

There are also political barriers in certain countries that will likely block access in some areas. 

EchoStar’s vision for using the band globally depends on standards currently being developed for 5G, Johnson said, including the nonterrestrial radio components that will be a part of how next-generation wireless services are defined and operate. This affects the level of interactivity between terrestrial and satellite networks.

“That’s really where we see S-band fulfilling a role that really hasn’t existed yet,” he said, referring to how satellites are playing a part in next-generation wireless plans for the first time to expand the footprint and capabilities of 5G.

The next big milestone for 5G’s development, being coordinated by the 3GPP standards organization, is Release 17 that is expected to include non-terrestrial components when it is unveiled early next year.

In the meantime, EchoStar is developing its European S-band business as it anticipates these future 5G opportunities. 

Cellular network operators are increasingly adopting cloud and other virtualization tools for their networks, potentially making it easier for satellite service integration.

Hughes Network Systems (HNS), which EchoStar owns, unveiled a hybrid terminal May 10 for its European customers called Hughes 4510, which automatically switches to S-band satellite services when moving out of terrestrial cellular coverage areas.

“I think once 5G starts to get built out terrestrially and the whole virtualization of networks occurs in satellite and terrestrial — really for the first time, converged together in a common group of standards — that’s [when] products that will support applications such as what the 4510 is targeted to do … should proliferate quite broadly and quite quickly,” Johnson added.

Dish Network announced a partnership April 21 to use cloud services from Amazon Web Services (AWS) to build out its 5G network across the United States. 

The satellite broadcaster plans to deploy wireless services through a 5G Open Radio Access Network (O-RAN), a virtualized network that mostly runs through the cloud.

Analysts see the partnership as signaling Ergen’s 5G ambitions for enterprise markets worldwide.

Johnson declined to comment on discussions EchoStar is having with potential partners as it looks to expand S-band services internationally.

“The system as a network will be architected in the most efficient way possible,” he added.

“So that most likely includes putting nodes for the terrestrial access points at, or very proximate, to data centers.”

SpaceX announced plans May 13 to install ground stations within Google’s data centers for its Starlink broadband satellites under their cloud partnership.

Accion Systems raises $42 million in Series C to accelerate development of 4th-gen propulsion system

Published

on

Space propulsion developer Accion Systems has closed its most significant funding round yet. The company raised $42 million in a Series C led by Tracker Capital, bringing its valuation to $83.5 million.

Along with the investment, Tracker Capital also acquired a majority stake in the company. This latest injection of capital will facilitate the development and manufacturing of the company’s fourth generation propulsion system, dubbed the tiled ionic liquid electrospray (TILE) system.

The TILE system uses electrical energy to push charge particles (ions) out its back to generate propulsion. While ion engines have been around for decades, Accion uses a liquid propellant, an ionic liquid salt, instead of gas. The liquid is inert and non-pressurized, meaning there’s no risk of explosion. It also results in a product that doesn’t need bulky components like ionization chambers, and an overall smaller and lighter weight system relative to the spacecraft – key considerations in space, where every gram of payload has a high price tag.

“It lets us build really, really small systems,” Accion co-founder Natalya Bailey explained to TechCrunch. “Instead of trying to take an existing ion engine the size of a Prius and shrink it down, we can start with very small systems because of this propellant.” And she does mean small – each thruster tile is about the size of a postage stamp.

The TILE system is also scalable and modular, meaning it could feasibly be used on anything from cubesats to propelling an interplanetary spacecraft, Accion CEO Peter Kant added in a recent interview with TechCrunch. “It’s one of the few occasions where the total addressable market and the actual addressable market that we can serve are pretty closely aligned and almost overlap,” he said.

The newest generation of the TILE system is the same size as its predecessors, but Accion is increasing the number of emitters on a given chip – emitters being the technology that actually shoots out the ions, generating the momentum – by almost tenfold. “We get more ions per area and that gives us a whole lot more thrust with the same amount of space,” Kant said.

Accion is looking to ship the first fourth-gen thruster systems in the middle to late summer of 2022.

The TILE system was developed by Accion co-founders Natalya Bailey and Louis Perna while the two were at the Massachusetts Institute of Technology. The tech generated a ton of interest from big aerospace companies, but they decided to found Accion in 2014 rather than sell. The company manufactures and assembles its product at its facility in Charlestown, Massachusetts.

The TILE system was onboard commercial spacecraft, one with Astra Digital and one with NanoAvionics, that went up on SpaceX’s Transporter-2 launch at the end of June. Accion started by focusing on serving smaller spacecraft first, like cubesats, but Bailey said that was just the beginning.

“We’re going after that segment initially, and then intending to reinvest our learnings in building larger and larger systems that eventually can do big geostationary satellites and interplanetary missions and so on. The systems that went up on the most recent launcher [is] probably good for a satellite up to about 50 kilograms [. . .] For us, it’s on the smaller end of where we intend to go.”
