Xona Pulsar GPS Rival Nears Launch With Six Satellites
Xona will launch six Pulsar satellites on SpaceX in October 2026, starting tests of a centimeter-precision, jam-resistant commercial GPS alternative.
Summary
Xona Space Systems plans to launch six satellites on a SpaceX rocket in October 2026, beginning customer beta tests of Pulsar, a commercial alternative to GPS and European, Chinese and Russian navigation networks. Four satellites use Aerospace Labs platforms similar to Xona’s 2025 prototype, while two built at its Burlingame, California, headquarters will seed a planned 258-satellite constellation. Passing over mid-latitudes about eight times daily, they will provide centimeter-level positioning, versus GPS’s meter-level accuracy, with signals designed to work indoors and in cities. CEO Brian Manning believes their greater strength could also discourage jamming and spoofing.
Founded in 2019 by five engineers from Stanford University’s aerospace graduate program, Xona developed an architecture that avoids costly onboard atomic clocks by synchronizing with ground references. A software modification lets existing GPS receivers use Pulsar, easing adoption and regulatory approval. TimeBeat CEO Ian Gough plans to use the pilot to verify and correct device timing worldwide. Xona targets full coverage across the U.S., Europe, Japan and South Korea by 2028. It has raised just over $300 million, including $20 million from the U.S. Space Force. CTO Tyler Reid, whose doctoral research inspired Xona and who later worked on Ford self-driving cars, sees Pulsar supporting farming robots, autonomous vehicles and safer transportation across billions of potential devices.
Positives
- Six satellites launching in October 2026 will let Xona begin Pulsar beta tests with paying-market use cases.
- Centimeter-level positioning would substantially improve on GPS’s meter-level accuracy for autonomous vehicles and farming robots.
- Existing GPS receivers can access Pulsar through a relatively simple software modification, reducing adoption and regulatory barriers.
- Signals designed for buildings and dense cities could extend reliable positioning into environments where GPS performs poorly.
- Just over $300 million raised, including $20 million from the U.S. Space Force, gives Xona substantial backing for deployment.
- Full coverage across the U.S., Europe, Japan and South Korea is targeted for 2028.
Risks & concerns
- Initial mid-latitude coverage will occur only about eight times daily until more of the 258-satellite constellation is deployed.
- Government navigation signals remain free, creating a difficult commercial challenge for Xona’s paid alternative.
- Full regional coverage is not expected until 2028, leaving Pulsar dependent on a lengthy constellation buildout.
- Brian Manning’s claim that stronger signals could deter jamming and spoofing has not yet been demonstrated through full commercial operation.
- Pulsar must overcome increasingly common navigation interference while proving reliability for safety-critical autonomous transportation.
