Navigation independent of orbit.
The world's first commercially available GPS-denied navigation system for fixed-wing UAVs. Absolute position from the terrain itself: no satellites, no ground station, no cloud.
How TerrainSLAM knows where it is
Terrain-referenced navigation, rebuilt for small fixed-wing aircraft. Every fix ties the aircraft back to real coordinates, so errors don't pile up the way they do with dead reckoning.
Look down
A downward camera observes the ground passing beneath the aircraft. Processing compensates for heat shimmer, haze and changing light, and adapts as altitude changes.
Match the terrain
What the camera sees is matched against terrain data loaded before flight, onboard, to fix the aircraft's true position on the Earth's surface.
Feed the autopilot
Absolute coordinates go to the autopilot as an independent navigation source. Autopilot-agnostic and plug-and-play, with no ROS stack required.
Built for where GPS fails
Jammed, spoofed or simply unavailable, TerrainSLAM keeps navigating. The aircraft always knows where it is.
GPS-independent positioning
Zero reliance on GPS or any satellite signal. True global coordinates, not relative tracking or dead reckoning.
All-weather operation
Heat shimmer, fog, haze and changing light are compensated for in real time. Atmospheric interference is no longer a mission abort.
Altitude adaptive
Processing adjusts across the whole flight envelope, from low-altitude inspection runs to high-altitude survey.
Fixed-wing native
Built for higher speeds and forward-only flight from the ground up, not adapted from a quadcopter system.
Edge-native hardware
Runs entirely onboard on affordable off-the-shelf embedded computers, including Raspberry Pi and NVIDIA Jetson families.
At a glance
The Bizix stack runs on affordable, off-the-shelf embedded hardware. No expensive sensors, no data centres, no complex dependencies.
- Deploys in minutes, not days
- Plug-and-play with leading autopilot platforms
- No cloud connectivity required in flight

Where it flies
Anywhere GPS is a single point of failure.
BVLOS operations
An independent navigation source strengthens the redundancy case for beyond-visual-line-of-sight approval.
Mining and resources
Deep pits, canyons and remote sites where satellite coverage is poor.
Defence and security
Contested electromagnetic environments where GPS is jammed or spoofed.
Agriculture and infrastructure
Long survey runs, corridors, bridges and power lines.
Navigating Over Low-Feature Terrain: Water, Salt Pans and Honest Uncertainty
Open water, salt pans and uniform crops give a terrain matcher little to work with. What an honest navigation system should do when the ground goes quiet.
Designing a GPS-Denied Navigation Trial: Ground Truth, Metrics and Failure Cases
A trial that only flies easy ground on clear days proves very little. How to design a GPS-denied navigation trial that tells you something useful.
