Why a satellite timing service deal with Murata matters
Japanese electronics giant Murata Manufacturing has signed a memorandum of understanding with California-based startup Xona Space Systems, agreeing to explore how Xona’s satellite timing service — called Pulsar — could be embedded into components used by telecoms, data centers, financial networks, and industrial machinery. It’s a partnership that looks modest on paper but signals something bigger: serious industrial players are starting to hedge their bets against GPS.
Murata isn’t a household name in the way that Apple or Samsung is, but its fingerprints are on virtually every piece of modern electronics you own. The company makes microelectronic components — capacitors, filters, communication modules — that end up inside smartphones, cars, medical devices, and AI data center hardware. If Murata decides to bake Pulsar support into its timing devices and communications modules, Xona’s satellite timing service reach into real-world infrastructure could scale far faster than if the startup was selling direct to end customers on its own.
The quiet fragility of GPS-dependent infrastructure
Most people think of GPS as something their phone uses to find the nearest coffee shop. What’s less understood — even among technically literate audiences — is how deeply global navigation satellite systems are woven into critical infrastructure that has nothing to do with navigation. Cellular base stations use GPS timing to synchronize transmissions. Stock exchanges use it to timestamp trades. Power grids rely on it to coordinate switching events across long distances. Data centers use it to keep distributed systems in sync.
All of that depends on signals originating from satellites sitting roughly 20,000 kilometers above Earth — and those signals, by the time they reach the ground, are extraordinarily faint. That makes them vulnerable. GPS jamming and spoofing have become genuine operational concerns, not just theoretical ones. In conflict zones and contested airspace, GPS disruptions are now a regular occurrence. But the risk isn’t limited to warzones. Dense urban environments, where signal reflections off buildings introduce errors, and indoor facilities, where signals barely penetrate at all, present real-world reliability challenges for any infrastructure that needs sub-microsecond synchronization.
The industry has known about this fragility for years. What’s changed recently is the emergence of credible alternatives — and a resilient satellite timing service like Xona’s Pulsar is one of the most technically interesting ones.
What makes Xona’s Pulsar different
Xona’s core argument is straightforward: put satellites in low Earth orbit instead of medium Earth orbit, and your signals arrive at the ground roughly 50 times stronger. LEO satellites sit between roughly 500 and 2,000 kilometers up, compared to the 20,200 kilometers where GPS satellites operate. That proximity means the Pulsar satellite timing service delivers signals that are far easier to receive indoors, in urban canyons, and in industrial environments where traditional GNSS reception is unreliable.
There’s a geometry benefit too. Because LEO satellites move across the sky much more quickly than GPS birds, the angles between a receiver and multiple satellites change faster — which means positioning calculations can correct for multipath errors (the signal-bouncing-off-buildings problem) more effectively. For pure timing applications, this also translates into more consistent, higher-quality synchronization signals.
The tradeoff with LEO has historically been coverage: you need far more satellites to maintain continuous global coverage compared to a medium-orbit constellation. That’s why Xona is targeting a 258-satellite constellation at full build-out. But here’s the strategically smart part of their business model — a satellite timing service doesn’t actually need complete global coverage to be commercially useful. A data center in Frankfurt or a financial exchange in Chicago just needs reliable signal overhead at all times, which a partial constellation can deliver long before the full 258 satellites are in orbit. Xona is essentially sequencing its market entry to generate revenue from timing customers early, using that to fund the fuller navigation buildout later.
Murata’s role goes beyond evaluation
On the surface, this MOU is an evaluation agreement — Murata will assess whether Pulsar’s satellite timing service can serve its customers’ needs. But the relationship is deeper than a standard industry pilot. Murata’s corporate venture arm, Wonderstone Ventures, already invested in Xona at an early stage. That financial stake gives Murata a reason to want Xona to succeed, not just a reason to be curious about its technology.
The practical pathway here is Murata potentially integrating Pulsar signal reception into the communications modules and timing components it already sells to manufacturers across multiple industries. That’s a very different commercial dynamic than Xona having to convince each telecom operator or data center operator to adopt new receiver hardware. If the satellite timing service capability is baked into a standard Murata component, adoption becomes much more frictionless.
Xona has already signed similar agreements with established receiver makers. Furuno, the Japanese marine electronics company, and Hexagon, the Swedish industrial measurement group, have both committed to integrating Pulsar signals into commercial products. Murata adds a third distinct distribution channel — one with particularly deep roots in the consumer electronics and industrial automation supply chains that the others don’t cover as directly.
The MOU also scopes out some less obvious application areas, including off-road machinery in construction and agriculture. High-precision guidance for autonomous farming equipment and heavy construction machinery has become a serious market, and it shares the same signal-degradation problems as urban infrastructure — GPS works fine in an open field but struggles when a machine is working near large metal structures or in forested terrain. A stronger LEO-based satellite timing service could improve reliability in those edge cases, giving equipment manufacturers a dependable fallback when GPS signals degrade.
The broader race to fix the GPS dependency problem
Xona isn’t the only company pursuing this space. The UK government, stung by Brexit cutting it out of the EU’s Galileo program, spent years exploring a sovereign PNT capability before pivoting toward supporting commercial alternatives. The US Department of Defense has poured funding into resilient PNT research for years, acutely aware that adversaries have invested heavily in GPS jamming capabilities. Startups like TrustPoint and established aerospace players have various competing approaches in development.
What’s different about the Murata-Xona deal is that it’s squarely commercial rather than defense-driven. The narrative around GPS vulnerability has long been dominated by military and government applications. This partnership is about data centers and 5G — the unglamorous but economically critical infrastructure that modern economies actually run on. That framing matters for how the industry thinks about the problem, and it positions a commercial satellite timing service as a mainstream infrastructure concern rather than a niche defense priority.
For Murata, this is also a positioning play in a world where its own customers — hyperscale data center operators, telecom infrastructure builders, automotive manufacturers — are increasingly asking hard questions about supply chain resilience and infrastructure redundancy. Having a credible answer to “what happens if GPS goes down?” is becoming a selling point, not just a theoretical nicety.
Xona’s constellation is still years from full deployment, and there are real execution risks in building out 258 satellites. But the company has structured its commercial strategy to matter well before that milestone arrives. If Murata’s evaluation leads to actual product integration, the startup could have its satellite timing service embedded in critical infrastructure components before most people have even heard of Pulsar — which, when it comes to the unglamorous business of keeping the world’s networks in sync, is exactly how these things tend to work.
