🚀 The biggest problem isn’t the GNSS outage. ➡️ What matters is when the signal returns.

👉 The biggest challenge for vehicle localization isn’t at the tunnel entrance, but at the tunnel exit.

👉 This is because the first GNSS signals are often still unstable there. Multipath effects, signal shadowing, and signal reflections can interfere with positioning.

🔵 How does ANavS solve this problem?
Through intelligent sensor fusion. While traveling through the tunnel, the vehicle’s position is continuously tracked using inertial sensors and other vehicle sensors. At the exit, returning GNSS signals are integrated into the localization only after a quality and plausibility check.

The result:
🟠 Continuous vehicle localization—before, during, and after the tunnel.
🟠 Fewer position jumps upon GNSS re-acquisition.
🟠 Resilient positioning even in challenging environments.

💡 It is precisely these seamless transitions that are crucial for resilient navigation.
