Meet SAF2Nav: our new resilient navigation stack
In an era where GNSS reliability can no longer be taken for granted, SAF2Nav sets a new standard for resilient navigation. Developed by SBG Systems, this navigation stack goes beyond the limits of traditional inertia by fusing multiple data sources to deliver continuous, trustworthy positioning—even in the most hostile jamming and spoofing environments.
Built on nearly two decades of sensor fusion expertise, SAF2Nav combines a modular, plug-and-play integration framework with an advanced dual-stage integrity fusion engine. Together, they enable seamless third-party sensor integration while ensuring automatic outlier rejection, continuous integrity monitoring, and reliable performance across land, air, and marine dynamics.
SAF2Nav reflects our ongoing commitment to delivering navigation you can trust — today and tomorrow. This capability is available now through a simple firmware update for Ellipse series (version 3.3) and Ekinox/Apogee/Quanta/Navsight products (version 6.0) systems.
