FCC Clears Xona’s 258-Satellite Navigation Plan but Initially Limits Deployment to 16
Xona Space Systems now has federal spectrum authority for a planned 258-satellite navigation constellation, but it does not yet have an unrestricted path to deploy all 258 spacecraft. The Federal Communications Commission’s conditional authorization initially permits 16 satellites, leaving interference control, orbital-debris review and production-scale deployment as the program’s governing constraints.
The decision expands the license previously covering Xona’s Pulsar-0 demonstrator. It allows the California company to transmit independently generated commercial navigation signals in L-band spectrum adjacent to the GPS L1 and L5 channels, rather than on those same channels. That distinction is central: Pulsar is intended to supplement existing positioning, navigation and timing infrastructure without displacing GPS.
The authorization governs spectrum access under specified technical conditions. It is not certification that Pulsar has achieved Xona’s claimed accuracy, security, receiver compatibility or service reliability. Those performance claims will still have to be demonstrated as the operational constellation and customer equipment mature.
Interference protection remains a hard operating boundary
Xona says its proprietary waveforms are designed to avoid harmful interference with GPS, aviation navigation systems and other authorized services. The FCC’s conditions turn that design objective into an operating requirement: Xona must halt transmissions immediately if Pulsar causes harmful interference.
This coexistence requirement helps explain why the authorization is important without making it equivalent to service approval. L-band is already occupied by navigation systems supporting aviation, communications and other timing-dependent infrastructure. Introducing another signal nearby requires tight control of emissions and coordination with existing users, particularly when the new architecture is designed to produce substantially stronger signals at the receiver.
Xona attributes a projected signal strength of up to 100 times conventional GPS to orbital distance. GPS satellites operate roughly 12,500 miles above Earth, while low-Earth-orbit spacecraft generally fly from a few hundred miles to about 1,200 miles. The shorter transmission path can provide a stronger received signal, but Xona’s 100-times figure remains a company claim rather than a performance finding established by the FCC decision.
Low orbit also imposes a fleet-size tradeoff. A spacecraft closer to Earth covers less territory and moves across a user’s sky more quickly than a GPS satellite at medium-Earth-orbit altitude. Xona therefore plans 258 satellites to build toward continuous global navigation, rather than relying on a constellation numbering only in the dozens.
The first 16 satellites define the next deployment phase
Before Xona can deploy spacecraft beyond the initial 16, it must obtain further FCC approval based on an updated orbital-debris assessment. The authorization also sets deployment deadlines: half of the planned constellation must be in orbit by July 2032, with the full system completed by July 2035.
Those conditions make staged deployment more than a financing or launch-scheduling exercise. Xona must move from a demonstrator and small production batches to repeatable spacecraft assembly while maintaining spectrum compliance and satisfying the additional debris review.
Pulsar-0 launched in June 2025 and has completed more than 350 transmission passes across four continents, according to Xona. The company plans to launch six production satellites on a SpaceX rideshare mission in October 2026. Two buses in that batch were designed and built at Xona’s Burlingame, California, factory; four were produced through its relationship with Belgian manufacturer Aerospacelab.
The Burlingame facility opened in April and is intended to assemble the remaining spacecraft. That shifts the program’s focus toward factory throughput, environmental testing, supply-chain control and launch integration the less visible work required to turn a successful signal demonstration into an operational service.
Xona expects early commercial use to concentrate on precise timing for telecommunications, financial infrastructure and data centers. Six satellites could support intermittent service, while the company says roughly 16 operating spacecraft would provide more persistent timing coverage. Continuous global navigation would require a substantially larger portion of the planned fleet.
The October launch is therefore the next concrete engineering milestone, not the completion of Pulsar. It will begin testing whether Xona can translate conditional spectrum access, a low-orbit signal architecture and two satellite-production paths into the first operational layer of a 258-spacecraft network.
