Xona Space Systems, a California start-up building its own satellite navigation network, has raised $250 million just as its first production satellites reach orbit. The Series D round was “led by Steve Jurvetson’s Future Ventures, with participation from new and existing investors”, and “values Xona at $2.45 billion”, the company said in a release on 22 October.
The money arrives at the point where Xona has to turn a demonstration into a service. It says the round takes its “total capital raised since 2019 to more than $570 million”. Six new Pulsar satellites went up this month, and four of them are meant to begin beta service for paying customers in early 2027.
Six satellites in orbit, four aimed at beta service
The satellites flew on SpaceX’s Bandwagon-5 rideshare mission, which TSN covered on 20 October. Xona calls it its “largest launch to date”. According to the release, “Four will support initial beta service in multiple countries beginning in early 2027, while two spacecraft designed and manufactured entirely in-house will validate the architecture”.
The company’s chief executive, Brian Manning, set out the coverage in a blog post before launch. Four satellites built on an Aerospacelab bus will give “a revisit time of ~12 hours”. Early customers “across the US, Canada, and most of Europe will receive 8 broadcasts a day, each lasting approximately 25 minutes”.
That is intermittent coverage, not a replacement for GPS, and Xona says as much. Its first target market is critical timing infrastructure, where systems already carry precision clocks. A Pulsar signal passing overhead can act as “an independent check that helps a system determine whether the GNSS information it is receiving makes sense and whether it can be trusted”, Manning wrote.
Xona’s performance claims are still its own
Xona’s pitch rests on how GPS can fail. The release describes satellite navigation “signals vulnerable to jamming, spoofing and disruption”. It says Pulsar offers “centimeter-level precision and signals up to 100 times more powerful than GPS, with demonstrated resistance to jamming and the ability to reach receivers indoors”.
In a separate post on the round, Manning said a test satellite, Pulsar-0, launched last year, has made “more than 500 transmissions, demonstrated positioning accuracy better than two centimeters”, and shown that existing commercial receivers can be upgraded “without physical modifications”. These are Xona’s figures. No independent test results have been published alongside them.
The company also claims “the first and only FCC authorization for a private navigation constellation operating alongside government GNSS systems”. Manning described the change in focus this way: “The last several years were about proving that a commercial company could build a fundamentally better navigation system. Now we’re putting that system into operation.”
Xona says its factory in Burlingame is “manufacturing at a cadence of multiple satellites per week”. The two in-house satellites now in orbit were built by its Burlingame team.
A rare space bet from Jurvetson
The lead investor is the notable part of the deal. Jurvetson, whom Xona describes as “a longtime SpaceX board member” and an early backer, “has invested in just three space companies throughout his career: SpaceX, Planet and Xona”, according to the release. “The pace of innovation at Xona is remarkable,” he said. “In just over a year, the company has advanced from a validation mission to deploying the foundation of an entirely new global navigation network.”
Timing customers are the realistic first market
The valuation prices in a network Xona has not yet built. Four satellites passing overhead eight times a day can check a GPS fix, but they cannot give anyone continuous positioning. Full coverage needs many more spacecraft, and that is where the new money, and the claim of several satellites a week, will be tested. Until then, the most credible early customers are the ones Manning names: operators of timing systems that can coast on their own clocks between passes and use Pulsar as a second opinion.
That is a real market, and one where timekeeping itself is changing, from the vote to end leap seconds to chip-scale optical clocks that could one day be portable. A cheap, independent check against a jammed or spoofed GPS signal is easier to sell than a whole new navigation system.
The harder question is adoption. Xona’s claim that receivers can use Pulsar with a firmware update, rather than new hardware, is the most important number in the pitch, because it decides how quickly device makers can switch the signal on. Its performance figures, from the 100-times signal strength to the two-centimetre accuracy, come from the company’s own tests. Outside verification, and the first beta customers’ experience, will show whether they hold up in use.
The next milestone is the start of beta service in early 2027. Xona has not said when continuous coverage will begin.
