Small size, jam proof, optical navigation system for tactical UAS

Drones can now be truly autonomous,
thanks to NavGuard’s novel optical navigation technology.

Truly autonomous BVLOS missions, can now be conducted in an ever safer and controlled manner. Explore how our jam proof optical navigation technology impacts the entire drone industry and its ability to become truly autonomous, safe and robust.

Our onboard, self-sufficient optical navigation system takes live images of the terrain. These are matched in real-time to a stored map of the mission area. Sophisticated machine vision algorithms generates continuous, low latency positioning, completely independent to the GNSS service.

Example of a night mission where NavGuard is the primary navigation of a tactical drone flying and hovering at high altitude.

NavGuard’s Sensors Product Line

NavGuard enables a truly safe and sustainable 24/7 drone missions under full GNSS blackout. Optimized for low weight, small size and low power. We mix together cutting-edge machine vision technology together with high-end optics and sensor fusion, under lean architecture design to form a plug-and-play positioning module.

NavGuard’s Core

NavGuard’s Core Technology

NavGuard’s Core Technology is based on cutting edge machine vision algorithms that process live video stream of optical images at super speeds and high efficiency. These are then compared to an on-board geo infrastructure – maps. The lightning fast matching process generates a stream of low latency accurate positioning data, similar in nature to the data structure of GNSS messages, enabling true supplement of the GNSS service.

Innovative Proprietary Machine Vision Technology

Our proprietary machine vision algorithms operates on live imagery frames, taken from an on-board camera, to digitally and continuously compare / match them to an aerial map. This process defines a correlation between the real-time image and the map – thus associating the map’s grid to the image pixels. This allows the extraction of continuous and accurate pixel-coordinates, where every pixel in the image gets a globally referenced coordinate. By doing so in real-time, image-based elements are given real-world coordinates, which in turn generates a real-time low latency, accurate and drift-free positioning. Such positioning service is critical to tactical airborne platform due to their unpredicted flight patterns.

Jam Proof Navigation and Positioning

Unlike other navigation and positioning solutions, NavGuard cannot be interrupted or jammed as it is not required to communicate with external sources or components. NavGuard’s highly accurate and drift-free position solution makes it the only relevant technology, able to serve as a true long term GNSS replacement. This becomes even more important as GNSS interruptions and jamming have become a daily event. Therefore, militaries and global aviation regulatory agencies are toughening their requirements on navigational robustness. This applies for airborne platforms in general and drones in particular, demanding a robust redundancy navigation capability second to the GNSS.
