Xona Space Systems Offers Commercial Backup Amid Jamming Threats

A California satellite startup, Xona Space Systems, is developing a low-Earth-orbit navigation network called Pulsar, designed to provide a commercial backup to GPS and other government systems. The system is intended to offer high-accuracy location and timing services, including centimeter-level positioning, and is harder to jam due to its stronger signal and authentication features. Xona has launched its first production-class satellite, Pulsar-0, and plans to deploy a larger constellation of about 300 satellites. The company raised $170 million in Series C funding to accelerate deployment and has already seen significant interest from customers in various markets. This development was first reported by AeroTime.
