Xona bets a paid GPS alternative can win: Pulsar satellites start going live

Builds a low-earth-orbit satellite constellation (Pulsar) selling precision navigation and timing as a commercial service.

Enough device makers will pay for centimeter-level, jam-resistant positioning that a private constellation can out-earn a free government signal.

Over $300 million from venture investors since 2019, including $20 million from the US Space Force.

Five engineers met in Stanford University's aerospace graduate program; Tyler Reid's PhD thesis argued low-earth-orbit satellites could improve navigation. Over 'pizza and beer chats' they asked whether fixing GPS's jamming and precision limits could be a business. CEO Brian Manning's knee-jerk was 'this is dumb' — until he realized the market isn't the free service, it's the hardware: billions of devices sold every year that desperately want better performance.

A prototype launched in 2025 proved the architecture: satellites that keep time without expensive onboard atomic clocks by leaning on proximity to Earth and constant contact with ground-based sources of truth. In October 2026 a SpaceX rocket is scheduled to launch six satellites — four on an Aerospace Labs platform like the prototype, two built entirely in-house in Burlingame, California — as the foundation of the 258-satellite Pulsar constellation.

GPS was designed as a free public good: easy to jam and only meter-accurate, which is not enough for machines that act on their own position.

The money is in the hardware, not the signal: billions of receivers ship every year, so customers pay for better performance without Xona having to meter the signal itself.

Low-earth-orbit proximity lets satellites sync to ground truth rather than carry atomic clocks, the costliest part of navigation satellites.

A signal legacy chips can already hear means adoption without a hardware replacement cycle — and an easier regulatory road than a new broadcast.

Jamming and spoofing of satellite navigation are increasingly common in conflicts, and the US Space Force itself put $20 million in.

Competing with free means selling what it can't do — precision, indoor reach, jam resistance — and designing for the installed base: a signal old chips can hear makes billions of devices your market.

As of 2026-10-09, six satellites — four on an Aerospace Labs platform like the 2025 prototype, two built in-house in Burlingame, California — were awaiting a SpaceX launch later that month. Beta testing with customers such as TimeBeat begins once the constellation passes mid-latitudes about eight times daily. Xona targets full US, European, Japanese and South Korean coverage by 2028, with the US government clearly interested as jamming incidents multiply.
