Zero Industries is developing a light, cheap, plug-and-play GPS-denied navigation solution for drones in contested battlefield environments. We developed a Visual Positioning System (VPS) with Computer Vision and Data Fusion (VINS) for autonomous drone navigation. Our mission is to provide autonomy to every European defence asset, contributing towards a sovereign and independent Europe. We are supported by Project Europe and incubated by ISAE-SUPAERO, in Toulouse, France.
