SYSTEM-00 / ARCHITECTURE

The Tarysar Subsurface Detection System.

A three-module stack: distributed sensor cluster, sub-GHz mesh relay network, and edge-compute command interface. No GPS dependency. No cloud uplink required. Operational at 200m depth.

ARCH-01 / THREE MODULES

Sensor cluster. Mesh relay. Command interface.

The Tarysar SDS is deployed as a set of self-contained sensor cluster units, each housing passive acoustic transducer arrays, a ground-penetrating radar sub-system, seismic geophones, and a local edge processor.

Nodes form a 915 MHz LoRa mesh automatically on power-up — no pre-configuration, no base-station dependency. The command interface runs on a ruggedized tablet or laptop, receiving encrypted alert packets from the nearest mesh gateway node.

All classification logic executes at the edge. Operator terminals receive pre-classified event objects — not raw waveforms. Bandwidth requirement: <1 kbps per active sensor node.

SPEC-02 / SENSOR NODE

Sensor node specifications.

Technical parameters from controlled field test conditions. Performance varies with substrate type, geometry, and operating temperature.

Comm protocol 915 MHz LoRa mesh ISM band / sub-GHz; no GPS sync required; AES-256 encrypted link
Edge processor ARM Cortex-M class On-device signal classification; outputs event objects, not raw waveform
Battery endurance 72h standard pack Passive acoustic continuous; GPR active sweep every 30 min by default
Operating temperature -20°C to +55°C Extended range variant in development
Form factor Cylinder 120mm dia / 280mm length Magnetic wall-mount or ground-stake deployment variants
Alert latency <8 seconds Event onset to operator notification over mesh — tested at 4-node mesh

MODULE-03 / EFFECTOR

Autonomous effector: navigate, assess, act.

The effector module is a GPS-independent autonomous platform designed for tunnel and confined-space traversal. Navigation relies on dead-reckoning inertial odometry combined with real-time SLAM against a preloaded tunnel geometry map loaded at deployment. No satellite sync required. No external position reference.

When the sensor mesh classifies a confirmed threat event, the effector can be dispatched to the anomaly coordinates within the engagement envelope defined by the operator prior to deployment. Human-in-the-loop override is mandatory for dispatch — the effector does not act autonomously without explicit operator confirmation.

INTERFACE-04 / C2

Command interface designed for field conditions.

The command and control interface presents classified event data — not raw sensor waveforms. Operators see: event type, estimated position, confidence score, threat velocity and direction, and a decision prompt.

The interface is designed for ruggedized tablet or military laptop. Offline-capable: no internet connectivity required. Encrypted session over the local mesh gateway. Full event log with export capability for after-action review.

  • Human-in-loop at every stage

    Effector dispatch requires operator confirmation. Override available at any point in mission execution.

  • No cloud dependency

    All processing is edge-local. The C2 terminal communicates with the mesh gateway over a local encrypted channel — no external uplink required.

  • Event log with export

    Full timestamped event log. Exportable for after-action review, incident reporting, and pattern analysis over time.
