Compatibility

Backwards compatible.
Future proof.

Pulsar broadcasts alongside existing GNSS signals, delivering a seamless upgrade in performance within your current technology stack, unlocking localization at scale so you can focus on the differentiated challenges that set your product apart.

Upgrade capability, not hardware.

Upgrade capability, not hardware.

Works where you do. Upgrade your existing GNSS devices with Pulsar’s capabilities with a firmware update.

Plays nice with others. Bespoke frequency modulation broadcasts Pulsar’s dual-band signals alongside existing GNSS without causing interference.

Flexes to every need. Compatible across device classes from smartwatches to aviation-grade receivers.

Precision

Accuracy where it counts.

Ultimate accuracy for every device, delivered directly from Low Earth Orbit.

Meet your new signal. Pulsar’s X1 and X5 signals unlock native 2 cm x 4 cm spatial precision directly from Low Earth Orbit – no special hardware required.

No time to wait.  Faster orbital motion means convergence within seconds from startup -- meaning more time working and less time waiting.

Synchronized Certainty. Stable, ultra-precise temporal reference accurate to within 10 nanoseconds, fully traceable to multiple UTC standards.

Expected performance of full constellation in open sky.

POWER

Through trees.
Through walls.
Power through it all.

Pulsar is built for the environments where signals bounce, fade, and fail. With 100x stronger signal power at the device than GPS, it maintains high reliability in dense cities, under heavy foliage, and even indoors – ensuring consistent performance where it matters most.

Work confidently where GNSS doesn’t today.

  • See through walls. High strength signal maintains coverage inside low rise buildings, dense canopy, and roofs.

  • Deflect reflections. Faster orbital motion minimizes errors from reflected signals in complex or cluttered settings.

  • Power saving. With stronger signals, Pulsar unlocks unparalleled power efficiency for battery powered and embedded systems.

Encrypted.
Authenticated.
Enduring.

Pulsar is engineered with the world’s first range-authenticated navigation signal — so you can rely on high-precision navigation for ages to come.

Cryptographic trust

Fully authenticated digital signals based on provable cryptography standards provide robust protection against spoofed or forged positioning.

Jamming resistance

Stronger signals, custom waveforms, and dynamic modulation techniques help Pulsar maintain performance even in contested or noisy environments.

Systemwide redundancy

Pulsar is designed for resilience, with built-in failover paths and rapid replenishment capabilities to ensure continuous service.

What is Pulsar?

Pulsar is Xona’s Low Earth Orbit satellite constellation providing next-generation positioning, navigation, and timing (PNT) services. It delivers centimeter-level accuracy, authentication, and signal strength up to 100x greater than legacy GPS, enabling reliable navigation even in urban canyons, forests, and in interference.

How is Pulsar different from GPS and other GNSS systems?

Unlike traditional Medium Earth Orbit (MEO) systems such as GPS, Galileo, or BeiDou, Pulsar satellites orbit in Low Earth Orbit (LEO) which broadcast an independent signal that doesn't interfere with existing GNSS systems while bringing centmeter-level accuracy, 100x signal strength, and state of the art protection against spoofing and jamming.

Where is Pulsar available today?

Signals from Pulsar-0 are actively being received and tested across regions of the United States and Canada, with full constellation service rollout planned over the next few years.

How does Pulsar integrate with existing GPS or GNSS receivers?

Pulsar is compatible with most standard GNSS hardware. Many receivers can ingest Pulsar signals via firmware updates, enabling hybrid PNT performance that blends Pulsar’s LEO accuracy and authentication with legacy GNSS coverage for seamless global operation.

How many Pulsar satellites will be launched?

The planned constellation includes approximately 300 satellites to ensure continuous global coverage, with Pulsar-0, the first production-class satellite, already in orbit and validating key technologies for signal authentication and performance.

How can I start developing with Pulsar?

Developers can request access to Pulsar test data, receiver specifications, and software development kits (SDKs). Integration tools allow evaluation with existing GNSS receivers and simulated performance of the complete Pulsar constellation.

What is LEO PNT?

Pulsar is among the first operational LEO PNT constellations. Low Earth Orbit Positioning, Navigation, and Timing (LEO PNT) is a new architecture for satellite navigation that uses fast-moving satellites 20 times closer to Earth than GNSS, delivering stronger, more secure navigation signals.
