RangeMark Launches Patented Long-Range Marker Identification for Drones – 1 km Detection, No GPS or RF

Where AI vision estimates, RangeMark by Sodyo Ltd. decides. Built on 30-plus patents, the technology delivers deterministic identification of passive, battery-free markers at ranges conventional visual codes were never built to reach — with no GPS, RF, cellular, or network connectivity.

, /PRNewswire/ — Autonomous drones have never seen better. AI-powered vision can detect, track, and classify objects with remarkable sophistication. Yet one gap has stayed stubbornly open across the industry: a drone can capture a crisp image of an object hundreds of meters away and still not know what it is looking at. It can estimate. It cannot confirm.

Today, RangeMark closes that gap. A patented long-range visual identification technology from Sodyo Ltd., RangeMark lets drones and remote systems detect a passive marker in the visual field from up to 1 kilometer away, then decode it into a unique, machine-readable identity — returning a deterministic verification result rather than a probabilistic guess. It requires no GPS, no cellular, no RF, and no network connectivity.

The distinction matters more as autonomy scales. AI vision can tell a drone that it is probably looking at a rooftop, a vehicle, or a person. RangeMark tells it which rooftop, which vehicle, and — critically — whether that person is a friendly force.

Alon Raz, CEO of Sodyo: “The industry has done extraordinary work teaching drones to see. But seeing was never the hard part – knowing is. RangeMark turns a marked point anywhere in the physical world into a point of certainty, from up to a kilometer away, with nothing but a camera and a printed marker, something no existing visual technology can deliver at that range. It took more than a decade of patented work to make it that simple. When a machine can be certain, it can be trusted to act on its own.”
