Advanced GPS-Free Navigation for UAVs
Navigation Without Satellites
The Folterra project presents advanced navigation systems that allow UAVs to operate reliably in environments where GPS/GNSS signals are jammed, spoofed, or completely unavailable. The approach combines artificial intelligence with multi-sensor data to create a precise, resilient, and scalable navigation solution.
Using Existing UAV Sensors
Most UAVs already carry sensors such as:
​
-
Inertial measurement units (IMUs)
-
Cameras (day/night, visible or infrared)
-
Barometers and magnetometers
​
Folterra’s AI-based system takes these data streams, analyzes them in real time, and fuses them into a single, reliable positioning solution. This means many UAVs can become satellite-independent without adding extra hardware.
Enhanced with Folterra’s Sensor Module
For missions that demand maximum accuracy, a compact hardware module integrates an array of sensors — including visual, inertial, and range-finding devices. The module connects seamlessly to almost any UAV platform, giving operators a plug-and-play upgrade to GPS-free autonomy.

Core Capabilities

Adaptive Visual-Inertial Navigation
By combining motion data from onboard cameras with inertial measurements, the system continuously estimates position and orientation. AI algorithms correct for drift and adapt to changes in lighting, terrain, or environment, ensuring accuracy even in GPS-denied areas.

Terrain-Aware Mapping
The system recognizes terrain features and correlates them with existing elevation and surface data. This allows UAVs to navigate confidently in forests, mountains, urban canyons, and low-altitude missions — where satellite signals are weakest.
​

Autonomous Decision-Making
Onboard intelligence makes UAVs more than just stable flyers, it makes them adaptive decision-makers. The system can reroute around obstacles, maintain mission objectives during interference, and ensure safe flight without operator input.
​
Resilience and Safety
-
Immune to GPS jamming and spoofing
-
Operates day and night, in variable weather
-
Safe low-altitude flight with obstacle awareness
-
Built-in redundancy for mission continuity
Scalable Across Platforms
The navigation technology demonstrated in Folterra can be deployed as:
​
-
Software-only, using existing UAV sensors
-
Hardware + software module, for any UAV that needs added resilience and precision
​
This flexibility allows defense, emergency response, industrial, and commercial operators to quickly field UAVs that navigate anywhere, no satellites required.
