GNSS (GPS) creates upwards of $500B in economic value in North America every year, supporting everything from consumer applications, to transportation, to time sync for critical infrastructure. As these industries progress towards autonomy, the performance and security demands of their Position, Navigation, and Timing (PNT) systems are increasing beyond what GNSS can support, leaving a need for a cost-effective global solution.

Using lessons we've learned at places like SpaceX and Blue Origin, Xona is building a modern commercial satellite system at the rapid pace of the new space industry leveraging the recent wave of technology and regulatory advancements. Building on our patented small satellite architecture, we are developing a robust and accurate service that is an independent alternative to GNSS rather than a correction, solving the longstanding challenge of obtaining a reliable high accuracy solution. Our satellite system will provide the first ever high-accuracy global navigation and timing services with the security and resilience that modern applications need to operate safely at scale.

As an RF Engineer at Xona, you'll be designing, implementing, testing, and optimizing RF wireless systems to enable our next-generation GNSS system. From spacecraft payload electronics to ground monitoring systems, your work will ensure the end-to-end RF broadcast system delivers Xona’s high-accuracy and high-precision PNT service.
