Xona raises $170M to build a GPS replacement with 100x stronger signals
What's the deal? Xona Space Systems has raised $170M in a Series C led by Natural CapitalDealroom has a profile for this one. Try Dealroom →, with participation from a group of venture and strategic investors.
The Burlingame, California-based company is building Pulsar, a commercial GPS alternative in low Earth orbit (LEO) designed to deliver centimetre-level accuracy and signals 100 times stronger than traditional GPS — compatible with existing devices via a software update.
The capital will fund deployment of a 258-satellite constellation and scale production at Xona's new California factory, with the first US-made satellites set to launch later in 2026.
Why now? GPS, designed more than 50 years ago, is increasingly vulnerable to jamming and spoofing — a critical problem as autonomous vehicles, drones, precision agriculture, and defence systems demand far greater positioning reliability than legacy infrastructure can provide. Rival nations are also investing heavily in next-generation LEO navigation, making this a race with national security stakes.
Xona has been building toward this moment. In 2025 it broadcast the first fully authenticated satellite navigation signal from orbit and recorded the highest positioning accuracy ever achieved from space. More than a dozen commercial receiver partners are already tracking Pulsar signals, with field testing underway across agriculture, construction, and defence.
What could go wrong? Building and launching 258 satellites is an enormous undertaking. Delays in constellation deployment would leave Xona's commercial proposition incomplete — a handful of satellites cannot replace GPS. The company also faces competition from well-funded government-backed programmes in China and Europe pursuing similar LEO positioning infrastructure.
The signal: Xona is part of a new class of companies betting that the infrastructure layer of the autonomous era — positioning, timing, connectivity — is as investable as the machines that depend on it. The round's investor mix is telling: alongside traditional VCs sit industrial and defence-adjacent players like HexagonDealroom has a profile for this one.
