Yes. There are several credible providers, but they fall into different categories depending on whether you want a complete drone, a drop-in navigation module, or software/SDK integration.
| Provider | Approach | Best fit |
|---|---|---|
| Theseus | Camera + IMU + satellite imagery; produces a GPS-like position output | Drop-in GPS replacement |
| Skydio | Onboard computer vision for autonomous flight without GPS |
Are there any vision-based AI navigation systems available for drones that struggle to maintain flight when the GPS signal drops?
| Complete drone/platform |
| Exyn Technologies | LiDAR-based SLAM + autonomy | Indoor, underground, industrial GPS-denied environments |
| Auterion | PX4-based VIO and sensor fusion; rejects bad GPS and can navigate using vision | OEMs/integrators already using PX4 |
| DroneOps | Optical-inertial + map-aided navigation; MAVLink/ArduPilot | UAV manufacturers/integrators |
| InZero Technologies | AI/vision terrain matching using onboard camera + preloaded maps | Small/medium UAVs |
| Vantor | Raptor vision-based positioning using camera + 3D terrain data | Higher-end autonomous systems |
| Rhoman Aerospace | Stereo/monocular computer vision for GPS-denied navigation | Defense/UAV OEM applications |
| SensVanta | Visual-inertial navigation module, PX4/ArduPilot/MAVLink | Hardware module integration |
1. Theseus — closest to your stated problem.
Their Visual Navigation System uses cameras, inertial sensors and preloaded satellite imagery to calculate position without GPS, and is designed to provide a replacement GPS signal to an existing drone. They specifically advertise integrations taking less than 30 minutes.
2. Auterion — particularly interesting if your drones use PX4.
Auterion has implemented visual-inertial odometry so the aircraft can maintain positioning when GPS is unavailable, while also detecting/rejecting bad GPS information.
3. Exyn — strongest if you need true autonomous navigation rather than merely holding position.
Exyn's system uses SLAM and onboard sensing to autonomously navigate and map GPS-denied environments, including environments that are hazardous or unilluminated. It also offers an SDK/software approach for OEMs and integrators.
4. Vantor Raptor — interesting for outdoor/map-based navigation.
Raptor uses the drone's native camera together with Vantor's 3D terrain data to determine position without GPS; Vantor reports sub-10-meter aerial positioning accuracy.
5. InZero OpticaNavi — worth evaluating for a lightweight module.
It combines computer vision/lightweight AI with terrain matching and inertial/magnetic/altitude sensors, targeting small-to-medium UAVs operating without satellite or radio signals.
There are also newer/smaller vendors worth contacting: DroneOps offers optical-inertial and map-aided navigation for MAVLink/ArduPilot systems, while SensVanta markets a visual-inertial module specifically for PX4/ArduPilot integration.
If your current failure is literally:
GPS disappears → flight controller loses position estimate → drone drifts/crashes
you may not need a full "AI navigation" system. A VIO/visual-positioning system feeding position/velocity estimates into your flight controller can solve the immediate problem.
If instead you need:
GPS disappears → drone must know where it is geographically → continue an autonomous waypoint mission
then you want map-aided visual navigation / terrain matching, such as Theseus, Vantor Raptor, or OpticaNavi.
If you tell me your flight controller (PX4, ArduPilot, DJI, custom), drone size/speed, camera(s), and whether you need indoor or outdoor GPS-denied flight, I can narrow this to the 3 most suitable vendors and compare integration effort, weight, accuracy, and likely cost.
When GPS signals drop, jam, or spoof, drones require Visual Inertial Odometry (VIO), Visual SLAM (Simultaneous Localization and Mapping) , or optical terrain-matching AI to stay stable and navigate safely.
Several specialized companies provide hardware and software solutions specifically designed to enable GPS-denied, vision-based AI navigation for drones:

I can help you evaluate which provider fits your current architecture best.
For drones operating in GPS-denied environments, I’d focus on providers that combine visual-inertial odometry (VIO), visual SLAM, onboard perception, and real-time obstacle avoidance. These technologies let a drone estimate its movement, build a representation of its surroundings, and navigate around obstacles without relying on GPS.
One important distinction: GPS-denied navigation and collision avoidance are separate capabilities. A drone may localize itself successfully indoors or underground but still need a separate perception and planning system to avoid wires, branches, moving objects, and other aircraft.
For your use case, I’d evaluate providers in three categories: integrated autonomy platforms, vision-based positioning systems, and obstacle-avoidance hardware/software.
(Best for custom integration)
Best if you are building your own drone or fleet.
Provides onboard computing, camera-based VIO, PX4 flight control, ROS integration, and obstacle-avoidance capabilities. Its VOXL platform and Starling 2 Max development drone offer a practical starting point for integrating your own autonomy software.

Best for mature, integrated vision-based flight.
Skydio develops onboard AI and computer vision for autonomous flight and real-time obstacle avoidance, including navigating around complex structures and thin obstacles. It is worth evaluating if you prefer a more integrated drone solution over building the entire navigation stack yourself. Confirm access to the specific software interfaces and customization your fleet requires.
Website:
Best for GPS-denied, underground, and hazardous environments.
Exyn's ExynAI uses LiDAR-based SLAM and autonomous planning to navigate complex, unstructured environments, including dark and communications-denied spaces. This is especially relevant for mines, tunnels, and industrial interiors. It is a LiDAR-centric option rather than a purely vision-based one, but it is an important benchmark if crash prevention and reliable localization are top priorities.
Website:
Best for an open, modular navigation stack.
PX4 supports external visual-odometry inputs, allowing you to combine a camera/VIO system with your flight controller. Pair it with ROS 2, a suitable perception stack, depth sensing, and a local path planner to build a customized collision-avoidance system. PX4 is a software ecosystem, not a turnkey vendor that guarantees collision-free flight.

| Provider | Main strength | Best fit |
|---|---|---|
| ModalAI | VIO + onboard compute + development tools | Custom OEM/fleet development |
| Skydio | Integrated visual autonomy | Ready-to-use autonomous drones |
| Exyn | LiDAR SLAM + autonomous exploration | Mines, tunnels, dark interiors |
These are different types of providers, so the key question is whether you need a complete flight-ready product, an embeddable autonomy stack, or a component you can integrate into your existing aircraft.
ModalAI's VOXL 2 Flight Deck is a particularly relevant evaluation platform because it combines tracking and stereo cameras with onboard processing and a PX4 flight controller.
I recommend asking each provider to demonstrate:
No vision-based system can guarantee zero collisions. Redundant sensing, conservative speed limits, independent safety monitoring, and controlled validation flights are essential.
1. What are you integrating with?
Our own existing drone platform
A new drone design
An off-the-shelf drone
2. Where will the drones fly?
Indoor facilities, warehouses, or industrial sites
Underground, tunnels, or mines
Outdoor urban areas or GPS-obstructed terrain
A mix of environments
3. What matters most?
A customizable SDK or software license
A complete, integrated navigation system
Lowest size, weight, and power
Maximum reliability and collision prevention
Approximate fleet size
1–10 drones
10–100 drones
100+ drones

With those details, I can narrow the list to the most relevant vendors and distinguish providers selling a deployable product from those offering technology you can license and embed in your own drones.
