Xona, the California-based startup building a low-Earth-orbit alternative to GPS, has closed a $170 million Series C round to accelerate deployment of its Pulsar positioning, navigation, and timing (PNT) constellation and expand its in-house manufacturing capacity. The round, announced March 26, brings the company's total funding to roughly $320 million and positions Xona as the most well-capitalized commercial PNT player going after one of the most strategically important — and historically government-controlled — pieces of global infrastructure.
The financing was led by Mohari Ventures Natural Capital, with participation from Craft Ventures, ICONIQ, Woven Capital, NGP Capital, Samsung Next, and Hexagon, among others.
[HIGHLIGHT]Xona is building a 258-satellite LEO constellation called Pulsar, designed to provide signals that are stronger, more resilient, and harder to jam than GPS — while remaining compatible with existing GPS user equipment. The company says the entire constellation can be built "for the cost of a single GPS satellite on orbit today."[/HIGHLIGHT]
The Round in Detail
The $170 million Series C is the largest financing in Xona's history and follows the $150 million the company had raised across earlier rounds. The capital will support two principal initiatives: production at a new factory in Burlingame, California, and the broader buildout of the Pulsar constellation.

Mohari's lead is itself notable. Jay Zaveri, founder and partner at Natural Capital and a strategic partner to Mohari Ventures, articulated the underlying thesis in stark terms when he described GPS — designed 50 years ago — as a system whose signals are "weak, unencrypted, easily jammed," and said "the world has outgrown it."
That framing captures the investor case for Xona: GPS is foundational infrastructure that the entire global economy depends on, but it was architected for a different era and a different threat environment. Pulsar is a bet that the next era of resilient navigation and timing will run, at least in part, on commercial LEO.
What Pulsar Actually Is
Pulsar is a commercial PNT service designed to operate as an alternative or backup to the Global Positioning System. GPS underpins navigation and timing for both military and civilian applications — from precision-guided weapons to mobile networks to financial settlement systems — but its signals are vulnerable to jamming, spoofing, and other forms of disruption, particularly in contested environments.
Xona's satellites operate in low Earth orbit, much closer to Earth than GPS's medium Earth orbit. That proximity means Pulsar's signals arrive on the ground much stronger than GPS signals, making them inherently harder to jam and easier to authenticate. Combined with modern signal architecture, Pulsar is intended to provide a meaningful step-change in PNT resilience.
A key product decision: Pulsar is designed to work with existing GPS devices. Xona moved its signal architecture from C-band to L-band frequencies after determining that most users lack compatible C-band equipment. That compatibility decision was, in CEO Brian Manning's framing, the unlock for scaling.

Constellation Buildout
Xona's first production-class satellite launched in June 2025, and over a dozen commercial receiver partners are already tracking its signals — an early validation that the technology works as designed and that user-equipment compatibility is real.
The next major milestone is later this year. The company plans to launch six additional satellites on a SpaceX rideshare mission in the fourth quarter of 2026, with broader deployment ramp-up expected in 2027.
The longer-term target is striking: 258 satellites within a few years, at a total program cost the company says is comparable to a single GPS satellite on orbit today. That economics gap — driven by LEO mass production rather than bespoke MEO satellite procurement — is the central reason a commercial company can credibly attempt what only governments have historically built.
Vertical Integration and Manufacturing
A meaningful portion of the Series C capital will fund Xona's shift toward in-house spacecraft manufacturing. Early Pulsar satellites were built in partnership with Belgian manufacturer Aerospacelab. Of the six spacecraft scheduled to launch this year, four were produced by that partner and two are the first designed and built in-house at Xona.
The company expects to manufacture the remainder of the constellation internally. That move toward vertical integration is consistent with the broader pattern across mass-manufactured satellite operators: as constellation size and per-unit cost pressure grow, owning the manufacturing process becomes a structural advantage.
Beyond Burlingame, Xona is expanding its operations footprint:
- **Montreal** — Growing operations to tap local aerospace engineering talent
- **London** — Newly opened office to support European customers
- **Furuno (Japan)** — Established positioning and navigation industry partnership
- **Topcon** — Additional positioning and navigation industry partnership
Customer Strategy
Xona's go-to-market approach is unusual for a constellation operator: it does not need the full 258-satellite system in orbit before delivering meaningful commercial value. Initial demand is expected from industries requiring high-precision timing — telecommunications, banking, and data centers — which can begin using Pulsar with a relatively small number of satellites in orbit.
That phased revenue profile gives Xona a more capital-efficient growth path than a typical broadband mega-constellation, where service quality depends on a large number of satellites being live at once.
In parallel, Xona is targeting U.S. military users. The Space Force awarded the company a Strategic Funding Increase (STRATFI) agreement, combining $20 million in government funding with $30 million in private capital — $50 million in total — to support development of the constellation. The STRATFI signal is meaningful: it indicates real Department of Defense interest in commercial PNT alternatives, not just tolerance.
[QUOTE]"There's a very clear need. They're looking to diversify their PNT capabilities … and the administration is very much looking at commercial capabilities." — Brian Manning, Co-Founder and CEO, Xona[/QUOTE]
Why It Matters Now
The timing of Xona's raise reflects three converging forces in the broader PNT and defense-tech environment:
1. **GPS vulnerabilities are operationally visible.** Jamming and spoofing of GPS signals — once a niche concern — have become routine in conflict zones and have spilled over into commercial aviation, shipping, and civil applications. The cost of GPS dependence is no longer theoretical.
2. **Critical infrastructure depends on PNT.** Telecom networks, financial settlement systems, and data centers all rely on precision timing that today comes mostly from GPS. A resilient commercial alternative is increasingly being treated as a category of critical infrastructure in its own right.
3. **The Pentagon is buying commercial PNT.** The STRATFI agreement and broader military interest in alternative PNT signal a structural shift: defense procurement is moving from "GPS only" to "GPS plus commercial augmentation," opening a meaningful procurement market for companies like Xona.
[HIGHLIGHT]Xona is positioned at the intersection of two of the most important trends in defense-tech: the operational reality that GPS is no longer a sufficient single point of trust for navigation and timing, and the procurement reality that the Department of Defense is now actively buying from commercial PNT providers.[/HIGHLIGHT]
What the Money Funds
The $170 million Series C is targeted at three priorities:
- Scaling production at the new Burlingame factory
- Continuing constellation deployment, including the Q4 2026 SpaceX rideshare launch and the 2027 ramp-up
- Building out international operations and customer-facing teams across Montreal, London, and partner geographies
The Bottom Line
Xona's $170 million Series C is more than a fundraising milestone. It is the clearest signal yet that commercial LEO PNT has moved from aspirational pitch to credible infrastructure category. The company has a launched satellite, more than a dozen receiver partners actively tracking its signals, a clear constellation roadmap, a vertically integrating manufacturing strategy, and now $320 million in total capital plus a Space Force STRATFI agreement.
If Pulsar can hit its 2026 deployment milestones and ramp through 2027, Xona has a credible path to becoming the first commercial PNT operator at constellation scale — and a foundational layer for resilient navigation and timing across both the military and the commercial economy.
