VERTICAL-01 / MILITARY
Tunnel warfare detection without entering the tunnel.
Cross-border tunnel networks, IED emplacement routes, and fortified underground command infrastructure present a class of threat that aerial ISR and conventional ground sensors cannot address. The Tarysar SDS detects, localizes, and classifies underground activity from externally emplaced sensors — no entry required.
THREAT-01 / CONTEXT
The threat model: typology and operational patterns.
Cross-border military tunnel networks range from shallow excavations (3–8m depth, narco-construction methods) to deep-bore infrastructure with reinforced concrete lining, ventilation systems, and electrical power (10–50m depth). The deeper variants are the harder detection problem — GPR alone cannot reach them, and aerial ISR sees nothing.
IED emplacement tunnels are typically shallower (1–4m) and shorter (20–100m), with the detection challenge being that they are dug quickly and used once. The seismic and acoustic signatures of active excavation are the primary detection window.
Fortified underground command infrastructure requires persistent monitoring — the facility is built once, used repeatedly, and the activity pattern of personnel transiting it is the detection vector. This is where the 72-hour battery cycle of persistent Tarysar mesh nodes becomes operationally relevant.
| Type | Depth | Primary sensor |
|---|---|---|
| IED emplacement | 1–4m | Seismic + acoustic |
| Cross-border logistics | 3–30m | GPR + seismic |
| Reinforced command bunker | 10–50m | Acoustic (personnel) |
| Active excavation | any | Seismic (machinery) |
Classification from open-source reporting and field doctrine. No classified intelligence sources.
FIT-02 / REQUIREMENTS
How the Tarysar system addresses military requirements.
What the system does: detect, localize, classify, and alert — at ranges up to 200m per node. What it does not do: provide real-time map rendering of full tunnel networks, or operate as a standalone counter-UXO tool. It is a sensor-effector detection system, not a tunnel mapping survey instrument.
-
GPS-denied operation — by design, not by workaround
The entire communication and positioning stack is built for GPS-absent environments. 915 MHz mesh relay requires no satellites. Node-to-node positioning uses relative time-of-flight, not GPS coordinates. Standard condition: GPS jamming present.
-
ITAR-compatible hardware and documentation
Tarysar products are subject to US export control regulations. All defense program engagements include end-user certificate procedures. The hardware and software architecture has been designed with ITAR dual-use review in mind.
-
Two-person team deployment under 45 minutes
A 100m corridor with 4 sensor nodes can be deployed by a two-person team in under 45 minutes in tested conditions. Magnetic wall-mount and ground-stake variants accommodate different corridor surface types. No specialized equipment required for emplacement.
-
No entry required for detection
Sensors emplace at the perimeter of the suspected tunnel access points, intersections, or above known routes. Classification and alert happens before any operator decision to enter. Human-in-the-loop override governs effector dispatch at all stages.
-
72-hour persistent battery cycle
Passive acoustic and seismic modes run continuously. GPR active sweep cycles on 30-minute default intervals. Designed for persistent area surveillance, not scheduled inspection. Operational battery life: 72 hours on standard pack.
Defense program inquiry.
Qualified defense programs can request a technical specification brief and scenario discussion. We engage at the technical and operational level — program office, engineer, and field operator audiences.
