Senior GNSS Estimation Engineer

Description

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.

The navigation software team at Xona is responsible for developing and maintaining the computational   processes that run our space, ground, and operational systems. As a member of   this small fast-moving team, you’ll develop software to tackle problems in integer ambiguity resolution, precision orbit determination, clock estimation, user positioning, atmospheric modelling, and integrity for safety critical applications. You’ll also work closely with the payload software team to develop test procedures and validate your products on test and flight hardware.
