Xona's GPS Alternative Prepares for Launch
Original: Xona’s commercial GPS alternative is about to go live
Why This Matters
First commercial navigation constellation could redefine precision GPS markets worth billions.
Xona Space Systems will launch six satellites via SpaceX this month, beginning commercial operations for Pulsar, a precision navigation alternative to GPS targeting self-driving cars and farming robots.
Founded in 2019 by five Stanford aerospace engineering graduates, Xona Space Systems is days away from its first operational satellite launch. Six satellites are scheduled to ride a SpaceX rocket into orbit this month — four built on Aerospace Labs platforms (similar to a prototype launched last year), and two built entirely in-house at Xona's Burlingame, California HQ. Those two represent the template for Pulsar, the company's planned 258-satellite constellation.
The pitch isn't to replace GPS so much as to supplement it. Government-operated navigation networks like GPS, Galileo, GLONASS, and BeiDou are free but susceptible to jamming and lack the centimeter-level precision required for autonomous vehicles and agricultural robotics. Xona's signals are stronger, more precise, and — critically — receivable by existing GPS hardware with only a software update, sidestepping a major adoption barrier.
The timing architecture is also notable: Xona's satellites maintain precision timing without onboard atomic clocks, instead leveraging low-Earth orbit proximity and ground-based synchronization. CEO Brian Manning told TechCrunch that while GPS appears free to end users, the real market is hardware — billions of devices sold annually to buyers hungry for better performance.
