When GPS Fails, What Do You Do?
April 20, 2026
GNSS (GPS) is no longer guaranteed in today’s operational environments. It can be:
- Jammed
- Spoofed
- Denied entirely
For autonomous drones, unmanned vehicles, or surveillance platforms, this doesn’t just pose a problem, it can end the mission.
At SentiSystems, we’ve developed a solution:
SentiNAV – a sensor fusion engine that enables reliable, real-time navigation without GNSS.
Why GNSS-Denied Navigation is Critical
From the battlefield to urban operations and offshore missions, GPS-denied scenarios are becoming the norm, not the exception. And most navigation systems simply aren’t built to survive them.
SentiNAV changes that. It delivers:
- Real-time fused data from IMUs, LiDAR, radar, and visual sensors
- Highly precise position and heading – even when satellite signals are unavailable
- “Plug-and-play compatibility” with modern and legacy platforms – integrate with your existing sensor park
Whether you’re operating ISR drones, autonomous ships, or UGVs in complex terrain, SentiNAV keeps your systems moving with full situational awareness.
“We don’t rely on a signal from space. We rely on sensors you already have.”
How It Works
1. Plug In Your Sensors Standard interfaces allow seamless integration with IMUs, LiDAR, radar, and visual systems.
2. Real-Time Sensor Fusion Our proprietary engine combines multi-modal sensor data for high-speed, high-precision navigation without relying on GNSS.
3. Export Clean Navigation Data Heading, velocity, and position are continuously delivered via ROS, CAN, or NMEA for easy integration.
The SentiSystems Advantage
SentiSystems is a pioneer in sensor fusion, founded on deep research from NTNU, one of Scandinavia’s leading tech universities. Our mission: to push the boundaries of autonomy, without compromise.
