Launching a commercial navigation alternative
Startup Xona Space Systems is preparing to test its commercial navigation and timing service as it launches six satellites into orbit. The upcoming launch aims to challenge government-provided satellite networks, such as GPS, by offering precise geolocation and timing data designed for hardware and devices.
Founded in 2019 by five aerospace engineering graduates from Stanford University, Xona developed an architecture allowing its satellites to maintain time without onboard atomic clocks by operating close to Earth and communicating with ground sources. The company solved technical challenges to ensure existing GPS receivers can use its signals through simple software modifications, easing regulatory pathways for broadcasting.
Satellite constellation and future rollout
A SpaceX rocket is scheduled to carry the six satellites into orbit. Four of the spacecraft are built around platforms from Aerospace Labs, while the remaining two were constructed entirely at Xona’s headquarters in Burlingame, California. These two internally built satellites form the foundation of the company’s planned 258-satellite operational constellation, named Pulsar.
Once in orbit and passing mid-latitudes about eight times a day, Xona will begin beta testing Pulsar with real customers, including electronic timing firm TimeBeat. By 2028, the company aims to deliver full coverage across the United States, Europe, Japan, and South Korea.
Market applications and backing
Unlike the meter-level precision of standard GPS, Pulsar is designed to offer centimeter-level precision. Xona states that the signal is powerful enough to be detected inside buildings, navigate urban environments, and deter potential jammers and spoofers.
To date, Xona has raised just over $300 million from venture investors, which includes a $20 million contribution from the U.S. Space Force. Company leadership sees potential applications for the technology in autonomous vehicles and civil aviation, aiming to provide a high standard of safety for mass transportation.
