The US Federal Communications Commission has granted full authorization for Xona Space Systems to operate the world’s first commercial navigation constellation alongside GPS. The California-based company’s Pulsar system will transmit signals up to 100 times stronger than GPS from low Earth orbit, using the same L-band frequency that existing receivers already support. The approval marks a fundamental shift in American navigation infrastructure, introducing private-sector competition to a domain that has been exclusively government-operated for decades.
What the FCC Decision Means
On August 4, 2026, Xona announced that the FCC had authorized its complete low Earth orbit satellite constellation to transmit commercial navigation signals. The decision extends an earlier license granted for Pulsar-0, the company’s demonstration satellite, which became the first commercial spacecraft permitted to broadcast radionavigation signals in the L-band spectrum used alongside GPS.
The expanded authorization covers the production constellation rather than a single test mission. It positions Xona as the only FCC-authorized private navigation constellation designed to operate beside government-run systems from the United States, Europe, China, and Russia.
“From the beginning, we were told that what we wanted to do was impossible,” said Brian Manning, Co-Founder and CEO of Xona. “A commercial company had never built a system like Pulsar, and no one had been authorized to introduce a new, high-power navigation signal alongside GPS. This decision is the culmination of years of engineering, testing, and coordination, clearing the way for a capability the world increasingly needs”.
Why Stronger Signals Matter
The core technical premise behind Pulsar is straightforward: signals from low Earth orbit arrive at ground receivers with far more power than signals from GPS satellites orbiting at medium Earth orbit, roughly 12,000 miles above the planet. Xona claims its signals will be up to 100 times stronger than GPS.
That power advantage translates directly into resilience. GPS signals are notoriously weak by the time they reach Earth, which makes them vulnerable to jamming and spoofing. A stronger signal is harder to drown out and harder to counterfeit. Xona’s proprietary signal incorporates a dynamic cryptographic watermark specifically designed to protect users against spoofing attacks.
The company engineered Pulsar for the established L-band rather than a less widely used navigation frequency. More than six billion Global Navigation Satellite System-enabled devices already rely on this portion of the spectrum, giving Xona a path to support existing receivers through software or firmware updates rather than requiring new hardware.
Regulatory Hurdles and Industry Coordination
Transmitting at higher power near GPS required Xona to prove to regulators that Pulsar would not disrupt existing navigation or aviation services. The company coordinated testing with the FCC, other US agencies, aviation stakeholders, and foreign governments.
This process assessed signal performance, interference risks, and coexistence with critical systems supporting aviation, emergency response, communications, and financial markets.
“Making room for something new required us to demonstrate that we understood the importance of what was already there,” said Christina Youn, General Counsel and Vice President of External Affairs at Xona. “GPS supports aviation, communications, emergency response, financial markets and countless systems people rely on every day. We did not ask regulators or the industry to take our claims on faith. We designed for coexistence, subjected that design to rigorous scrutiny, and then proved it through live transmissions from orbit”.
Orbital Testing Already Underway
Pulsar-0 has completed more than 350 transmission passes across four continents since its June 2025 launch. More than a dozen commercial receivers have independently tracked its live signals, and tests have demonstrated operation with existing GNSS hardware in real-world environments.
With regulatory clearance secured, Xona can now move from orbital demonstration toward deployment. The company plans to launch its first six production satellites in October 2026, expanding manufacturing at its Burlingame facility to support the deployment.
A Changing Navigation Landscape
The FCC approval arrives at a moment when GPS resilience has become a priority for US policymakers. Legislation included in the House-passed National Defense Authorization Act for fiscal year 2027 would direct the president to accelerate GPS modernization, including deployment of the full GPS IIIF constellation and prioritization of the L5 signal for civilian and military applications.
The US Space Force is currently operating 32 satellites in the GPS constellation and has contracted Lockheed Martin to build up to 24 next-generation GPS IIIF satellites, with 14 currently on contract. The GPS IIIF satellites will introduce anti-jamming capabilities 63 times greater than earlier generations for military users.
Xona’s Pulsar system is not intended to replace GPS. Instead, it functions as a complementary layer, offering a second source of positioning, navigation, and timing data that can operate independently or alongside the government constellation. For industries that depend on uninterrupted navigation—aviation, autonomous vehicles, financial trading, telecommunications—the availability of a commercial alternative represents a meaningful step toward reducing single-point-of-failure risk.
The company’s path from a single demonstration satellite to a fully authorized production constellation illustrates how private capital and commercial innovation are beginning to reshape a domain that was once the exclusive province of government space programs. Whether Pulsar achieves operational scale will depend on execution over the coming months, but the regulatory foundation is now firmly in place.
