PREGRAD

Passive detection and tracking of small drones.

Tactical map

Everything the sensors see converges on one map

How it works

Three steps from first contact to confirmation

  1. Detection

    Cameras watch the sector continuously. AI on the edge nodes recognizes a small drone in frame and produces a bearing to the target.

  2. Triangulation

    A second camera picks up the same target. From where the bearings intersect, the system computes its position and holds the track in real time.

  3. Confirmation

    The track goes onto the tactical map. The operator confirms it with a single action — the target stays under tracking.

System

Passive detection, edge processing, triangulation.

PREGRAD detects and tracks drones. The system emits no radio signals — its operation stays invisible to SIGINT. Recognition runs on AI at the edge nodes, with no cloud and no outside link, on a self-contained network. Once a target enters the cameras' fields of view, their data is fused, the position is built in real time and placed on the tactical map; the operator confirms the track with a single action.

One barrier for any terrain

Capabilities

Forest, industrial site, river — the system deploys on any terrain by the same principle.

Forest: posts labelled ПОСТ-СЕВЕР and ПОСТ-ЮГ, bearings onto a target above the trees
Forest: posts along the treeline · 09:15 · demo data.
Industrial site: warehouses and a rail interchange, observation towers
Industrial site: warehouses and a rail junction · 17:42 · demo data.
River: posts on both banks, bearings across the channel
River: posts on both banks · 06:52 · demo data.
Track with a trajectory tail: the history of the target's movement across the map
Trajectory tail: target movement over the last few seconds · demo data.

Pregrad SDK

Different sensors — one data stream. Tracks, bearings and statuses through one interface.
