Built on two decades of expertise

We’ve taken nearly two decades of sensor fusion mastery and evolved it. SAF2Nav isn’t just an update, it’s a new framework designed to secure missions against the growing threats of signal interference.

At the core of SAF2Nav lies a modular, security-driven architecture designed to ensure continuous, trustworthy navigation—even in contested and GNSS-denied environments. Let’s take a look in the following scheme:

Versatile sensor aiding

Select from a wide range of compatibility-tested external sensors or integrate your own generic aiding sources.

We provide a complete API, seamless integration into the sensor fusion algorithm, built-in quality monitoring, and automatic estimation of external sensor biases, scale factors, and misalignment.

Adaptive kinematic profiles

Maximize accuracy with profiles designed for your specific motion dynamics. Whether on land, air, or sea, the fusion algorithm adapts instantly to your vehicle’s behavior.

Dual-stage integrity

Built-in quality checks validate both raw input and output positioning, ensuring reliable, continuous, and mission-ready navigation.

Spoofing integrity supervisor

A new spoofing integrity supervisor monitors multiple sensors and parameters to detect anomalies instantly. Drastically reduces time-to-alert, critical for mission safety.

Our solutions are designed to reduce mission‑preparation workload. Since entering external information—such as weather conditions—adds operational constraints, our systems are engineered to operate fully autonomously. SAF2Nav automatically estimates the key error parameters of the aiding sensors, including internal biases, scale‑factor errors, wind speed for air‑data systems, or water speed for DVLs. It also compensates for any residual misalignment between the sensors and the vehicle to ensure reliable and accurate navigation performance.

SAF2Nav ensures reliable navigation everywhere: in harsh environments, under Electronic Warfare pressure, in demanding robotic applications, or in high‑precision survey missions.
As a flexible and powerful platform, it covers all key applications and we continuously evolve it to stay ahead of new threats, technologies, and mission challenges.
