Momentus Inc. (“Momentus” or the “Company”), a commercial space company offering in-space infrastructure services, and Xona Space Systems, a San Mateo-based startup creating a secure and precise Position, Navigation, and Timing (PNT) satellite service, today announced a service agreement to advance Xona’s 2022 Alpha mission.

Xona’s patent-pending system architecture is combining the efficiency and innovation of the new space era with the world of satellite navigation to help enable modern intelligent systems to operate safely in any conditions, anywhere on the planet. Once complete, their low Earth orbit smallsat constellation will provide a resilient alternative to Global Navigation Satellite Systems (GNSS) with more than 10x better accuracy.

Xona is developing a truly innovative system to enhance the reliability and precision of global PNT and GNSS. As an infrastructure company, Momentus is excited to partner with other like-minded pioneers to help build out the future services needed to enable human presence in space while improving life on earth,” said Dawn Harms, Momentus CEO.

We have been very impressed with the capabilities and services that Momentus offers with their Vigoride spacecraft,” said Xona CEO Brian Manning. “There is a rapidly growing demand for higher performance navigation and timing services as well as alternatives to GNSS. Forming this partnership with Momentus represents a key milestone in our technology development roadmap as we work towards our on-orbit demonstration and deployment of the full constellation to meet these needs.”
