Xona Space Systems closes $19M Series A to build out ultra-accurate GPS alternative | TechCrunch


For decades, the Global Positioning System (GPS) has maintained a de facto monopoly on positioning, navigation and timing, because it’s cheap and already integrated into billions of devices around the world. But Xona Space Systems thinks a more accurate system will be necessary to scale autonomous vehicles (AVs), advanced robotics and other technologies for the twenty-first century.

The startup plans to launch a satellite constellation in low Earth orbit that would act as a commercial GPS alternative. Called Pulsar, the network could potentially cost less to operate while offering more accurate geolocation data.

Xona was founded in 2019 by seven Stanford graduate school alumni; most met during grad school. CTO Tyler Reid went on to get his PhD there and worked in the university’s GPS Research Lab, later joining Ford’s autonomous vehicles group in 2017. He worked on “localization requirements,” or the level of navigation performance an autonomous vehicle or Driver Assist function needs to operate safely, and trying to develop or procure that tech.

Many vehicles today that integrate autonomous features use a combination of technologies, like cameras, lidar sensors and radar sensors to navigate. But Xona’s CEO Brian Manning said that while these sensors work well in structured environments, like cities, their efficacy is degraded in unstructured environments, like the middle of a desert. Fortunately, being unimpeded by buildings and other features, GPS tends to work very well in those places.

“The problem, though, is that GPS just has nowhere near the level of accuracy or really availability or robustness to be a complimentary sensor,” Manning said.

“That’s when we really started to realize how big the gap is between your GPS is today, and where the needs of at least the automotive market are and where they’re very quickly going,” he continued. “What if we could build a new GPS using more of the SpaceX mentality instead of the government contracting mentality?”

Xona’s approach is certainly more SpaceX than Boeing. The 31 satellites that provide GPS are all exquisite, ultra-expensive, and synchronized with nanosecond precision using massive on-board atomic clocks. In contrast, Xona’s Pulsar service is built on a patented “cloud architecture for atomic clocks,” as Manning put it, which he claimed will dramatically drive down the cost of each satellite but still provide orders of magnitude higher levels of accuracy. Think an accuracy of several centimeters, rather than meters.

Xona launched its first demonstration satellite in 2022 to demonstrate the core patented IP, and that satellite has now reached the end of its life. The first production-class satellite will launch in June 2025, and will be built by Belgian satellite manufacturer Aerospacelab. Xona is eventually aiming to launch a constellation of 300 satellites. Different customer groups will be able to start benefitting from the service even before the full constellation is operational, Manning said.

The company has designed its signal to be backwards compatible with many existing GPS chipsets, though some are “forwards compatible,” Manning said. But in general, chipsets will only need a firmware update to access the encrypted Pulsar signal.

While it might be hard to compete with a free service like GPS, Xona is convinced that there will be a huge market for advanced positioning, navigation and timing services due to the rise of AVs and other tech. Investors are behind this goal: on Tuesday, Xona announced the close of an oversubscribed $19 million Series A round led by Future Ventures and Seraphim Space, with participation from new investors NGP Capital, Industrious Ventures, Murata Electronics, Space Capital, and Aloniq.

Rob Desborough, a GP at Seraphim Space, described our dependence on GPS as an “absolute” in a statement. “Outages could cause incalculable damage to the global economy, while enhancement opens up whole new industries,” he said. “Waiting for GPS to fail, or for hostile powers to spoof it, is not an option for our security or commercial industries.”

This new funding round will go toward getting the first production-class satellite up in orbit, as well as building out the ground segment to support Pulsar and growing the 25-person team.

UnitedHealth CEO tells Senate all systems now have multi-factor authentication after hack | TechCrunch


UnitedHealth Group Chief Executive Officer Andrew Witty told senators on Wednesday that the company has now enabled multi-factor authentication on all the company’s systems exposed to the internet in response to the recent cyberattack against its subsidiary Change Healthcare.

The lack of multi-factor authentication was at the center of the ransomware attack that hit Change Healthcare earlier this year, which impacted pharmacies, hospitals and doctors’ offices across the United States. Multi-factor authentication, or MFA, is a basic cybersecurity mechanism that prevents hackers from breaking into accounts or systems with a stolen password by requiring a second code to log in.

In a written statement submitted on Tuesday ahead of two congressional hearings, Witty revealed that hackers used a set of stolen credentials to access a Change Healthcare server, which he said was not protected by multi-factor authentication. After breaking into that server, the hackers were then able to move into other company systems to exfiltrate data, and later encrypt it with ransomware, Witty said in the statement.

Today, during the first of those two hearings, Witty faced questions about the cyberattack from senators on the Finance Committee. In response to questions by Sen. Ron Wyden, Witty said that “as of today, across the whole of UHG, all of our external-facing systems have got multi-factor authentication enabled.”

“We have an enforced policy across the organization to have multi-factor authentication on all of our external systems, which is in place,” Witty said.

When asked to confirm Witty’s statement, UnitedHealth Group’s spokesperson Anthony ​​Marusic told TechCrunch that Witty “was very clear with his statement.”

Witty blamed the fact that Change Healthcare’s systems had not yet been upgraded after UnitedHealth Group acquired the company in 2022.

“We were in the process of upgrading the technology that we had acquired. But within there, there was a server, which I’m incredibly frustrated to tell you, was not protected by MFA,” Witty said. “That was the server through which the cybercriminals were able to get into Change. And then they led off a ransomware attack, if you will, which encrypted and froze large parts of the system.”

Witty also said that the company is still working on understanding exactly why that server did not have multi-factor authentication enabled.

Wyden criticized the company’s failure to upgrade the server. “We heard from your people that you had a policy, but you all weren’t carrying it out. And that’s why we have the problem,” Wyden said.

UnitedHealth has yet to notify people that were impacted by the cyberattack, Witty said during the hearing, arguing that the company still needs to determine the extent of the hack and the stolen information. As of now, the company has only said that hackers stole personal and health information data of “a substantial proportion of people in America.”

Last month, UnitedHealth said that it paid $22 million to the hackers who broke into the company’s systems. Witty confirmed that payment during the Senate hearing.

On Tuesday afternoon, Witty also appeared in a House Energy and Commerce committee, where he revealed that “maybe a third” of Americans had their personal health information stolen by the hackers

Portal Space Systems unveils Supernova, an ultra-mobile spacecraft | TechCrunch


The era of stationary spacecraft may soon be over.

Portal Space Systems, a company headed by propulsion expert Jeff Thornberg, is looking to help usher in a new renaissance in in-space transportation with its ultra-mobile Supernova satellite bus. Think of it as maneuverability-as-a-service — tech that could propel transfers from low Earth orbit to geostationary orbit in a matter of hours.

The 500-kg Supernova is designed to be payload agnostic and to survive on orbit for at least five years while being continuously maneuvered, the company said. It’s a far cry from legacy spacecraft, which are built to carry only as much propulsion as will be needed to maintain their orbit. Portal’s designed a novel propulsion system, called solar-thermal propulsion, that will produce a massive delta-V of 6 kilometers per second, to enable rapid transfer to cislunar space, or as maneuverable assets to support national security missions.

Portal was founded by space industry veterans Jeff Thornburg, COO Ian Vorbach and VP of engineering Prashaanth Ravindran. Thornburg’s career reads like a history of the space industry writ large. Spanning nearly 30 years, it includes stints at basically ever major aerospace organization: as a military officer in the Air Force; working on liquid rocket engine tech at Aerojet; five years at SpaceX, where he eventually became the second VP of propulsion engineering; working with storied entrepreneur Paul Allen at Stratolaunch; and as a director at Amazon’s Project Kuiper.

“Then I decided I didn’t really want the big company lifestyle and really wanted to dig in on some problems that were not being addressed by any other business, and so my cofounders and I founded portal space systems in November of 2021,” he said. “It’s the only time I feel like I’ve been able to predict the future, even close.”

Given that he has spent most of his career in launch vehicle development and propulsion, he started thinking about what would come next in the industry after SpaceX cracked the code on affordable, rapid, reliable launch. He noticed other trends, too: with more spacecraft launched to orbit than ever before, on-orbit collisions become more likely. On the defense side, Thornburg also started seeing more of a national security interest in responsive space capabilities and the ability for satellites to maneuver ‘without regret.’

But satellites aren’t designed for moving around a lot in orbit; in general, they are launched with enough on-board propulsion to keep them in their intended orbit, not to dodge other objects, and certainly not with out delta-V capability to go to higher orbit. Supernova is part of a new generation of spacecraft that are looking to change that.

The company has developed Supernova’s propulsion system in-house. The solar-thermal system leverages legacy tech designed by NASA and the the Department of Defense, while innovating specific subsystems to optimize for mission performance. For example, the company is bringing a proprietary heat exchanger to that solar thermal propulsion system to deliver even higher performance over a longer lifespan.

“I think the big forcing function here for commercial is just the proliferation of these LEO constellations that they have to maneuver around, and the forcing function for the DOD is China and the future engagement that people believe we’re going to have with them over Taiwan and other issues. Both of those things have come together at the same time, which has created the opportunity that I was hoping for, but didn’t quite predict it being this significant.”

Portal has raised an undisclosed amount of venture funding from unnamed backers, and the first Supernova development is fully funded, the company said. The team has also won over $3 million across five awards from the Space Force and the DOD, including a direct-to-phase II SBIR that’s focused specifically on developing responsive space operations.

Portal is aiming to conduct an in-flight demonstration in late 2025 or early 2026. But before that mission even launches, Thornburg said the startup is looking to scale its team — which stands at around 25 people, but anticipates will swell to up to 200 in 25 years — and grow manufacturing to support the production of multiple spacecraft per year after that first demonstration.

Instagram is updating its ranking systems to surface more content from smaller, original creators | TechCrunch


Instagram is introducing a few new changes to its ranking systems to better highlight content from smaller, original creators across the social network. The Meta-owned platform says that historically, creators with large followings and accounts that share reposted content have gotten the most reach on the platform. So now it’s seeking to give all creators an equal footing in terms of reach with a set of new changes that will be implemented over the next few months.

The platform is introducing a ranking change that will give smaller creators more distribution, replacing reposts with original content in recommendations, adding labels to reposted content and removing content aggregators from recommendations.

Instagram says it has been working on a new way to rank recommendations that will show eligible content to a small audience that it thinks will enjoy it. As people engage with the content, the top performing set of Reels will be shown to a slightly wider audience, then the best of these will be shown to an even wider group, and so on. Instagram believes this change will give all creators an equal chance of finding audiences.

In addition, if Instagram finds two or more identical pieces of content on Instagram, it will only recommend the original one. This change means that the original content will directly replace the reposted content in the app’s recommendations. The company notes that it won’t replace content if it has been significantly changed. For instance, Instagram won’t replace content that has been edited to become a meme or a parody. Plus, content will only be replaced in places where Instagram recommends posts, such as the explore page, Reels and in-feed recommendations.

Instagram is also going to start adding labels to reposted content that will link users to the original creator. The label will be visible to followers of the account reposting it. The company says that for now, the original creator or the account reposting the content have the option to remove the label. It’s possible that Instagram might not let creators remove the label in the future.

Another new change will go after meme accounts or pages dedicated to reposting other creators’ content. The company says that in the coming months, accounts that repeatedly post content from other users that they didn’t create or enhance will not be shown in recommendations. Instagram notes that this change won’t affect how it shows people content from aggregator accounts they follow.
