Xona Space Systems

Xona Space Systems develops and operates Pulsar, a commercial satellite constellation in Low Earth Orbit designed to deliver high-precision positioning, navigation, and timing (PNT) services. The constellation, planned for over 250 small satellites, operates approximately 20-25 times closer to Earth than GPS, providing centimeter-level positioning accuracy and signal strength roughly 100 times stronger than legacy GNSS systems. Pulsar's signals are encrypted and authenticated to resist spoofing and jamming, and the system is designed for compatibility with existing GNSS receiver hardware through software updates. The company launched Pulsar-0, its first production-class satellite, in June 2025 and is scaling constellation deployment through partnerships with satellite manufacturers while developing internal production capabilities at its Burlingame, California headquarters.

Xona operates a satellite-as-a-service business model, delivering PNT data to commercial and government customers across autonomous vehicles, robotics, precision agriculture, critical infrastructure, and defense applications. The company has received contracts and strategic funding from the U.S. Air Force Research Laboratory and SpaceWERX to develop GPS-alternative capabilities for contested environments. Xona remains privately held and has raised over $130 million in total funding, including a Series B round announced in June 2025.
