SALT LAKE CITY — (September 12, 2023) — Spirent has concluded a review of Xona Space Systems’ PULSAR™ production signals establishing feasibility for integration into the SimXona product line. Spirent will seamlessly integrate the Xona production signals as an evolution of the SimXona platform; support will become available to existing and new customers throughout 2024.

Xona is developing PULSAR™, a high-performance positioning, navigation, and timing (PNT) service built on a backbone of low Earth orbit (LEO) small satellites. Xona’s patented high-powered smallsat signals will improve PNT resilience and accuracy by augmenting global navigation satellite systems (GNSS), such as GPS, while operating with an independent navigation and timing system architecture.

“At Spirent, we are committed to supporting our customers throughout their entire LEO-PNT journey, from initial R&D to the production level,” stated Jan Ackermann, Director of Product Management at Spirent. “SimXona embodies this commitment by empowering our customers to evaluate and validate the integration of PULSAR™ capabilities into their PNT system, with the only Xona-certified simulation solution available in the market.”

“We’re excited to continue our collaboration with Spirent to evolve their SimXona and LEO-PNT products. We are committing to support future certification efforts to ultimately enable customers with high-performance test and evaluation tools,” said Bryan Chan, VP of Business Development and Strategy at Xona Space Systems.
