Xona raises US$250 million for a low-orbit navigation network that aims to replace GPS

What happened

• Xona Space Systems announced on October 22, 2026 a US$250 million Series D at a US$2.45 billion valuation, bringing its total capital to more than US$570 million.
• The round is led by Steve Jurvetson’s Future Ventures, with new and existing investors.
• According to CEO Brian Manning, they launched six Pulsar satellites this week. Four will begin serving users in 2027 and two are the first built entirely in its Burlingame factory.
• Xona says its Pulsar-0 prototype made more than 500 transmissions and achieved positioning accuracy better than two centimeters.

Why it matters

• GPS was designed for another world: today autonomous machines, power grids and telecom networks depend on precise time and position, and a weak signal from 20,000 kilometers away is easy to interfere with.
• Xona’s bet is to drop to low orbit. That is the company’s own reading and it still has to be seen working at scale: there will be no commercial service until 2027.
• For mining, precision farming and power operators in Chile, which today use medium-orbit constellations, an additional source of position and time would be a backup. Compatibility with existing receivers, according to Xona, is achieved without physical changes.

The number

Under 2 centimeters. Positioning accuracy that Xona says it demonstrated with Pulsar-0 in orbit.

Context

Pulsar-0 was last year’s test satellite. On October 7 the company named a new chief operating officer as Pulsar entered scaled production. All accuracy figures come from the company itself.

What’s next

• Service with four of the six satellites in 2027.
• Scaling to global coverage, with no satellite counts or dates.

Bottom line

Low orbit is filling with different uses: Google plans to send AI chips to orbit to escape the power limit on the ground, and Japan launched the MMX probe to Mars to bring back samples from Phobos.
