Designed to ensure ultra-reliable navigation performance for drones, autonomous systems and robotic vehicles, the company’s products provide robust protection in the most challenging of environments.
Resilient anti-jamming for UxV GNSS signals
The GNSS signals utilized for UAV and unmanned systems navigation, positioning and autonomous operations are highly susceptible to radio-frequency interference, both from unintentional sources as well as intentional attacks.
Small drones utilized for many commercial and industrial applications may crash or become highly unstable if their autopilots cannot compensate for sudden signal loss. The continued widespread use of RF devices and the expanding availability of low-cost jamming devices have caused these issues to become even more of a concern as time goes on.
