HAWK

Cableless Seismic Recording Technology

The Hawk SN11 Field Station Unit (FSU) is a rugged, cableless field digitizer designed for high‑performance seismic acquisition in demanding environments. Built within a military‑validated aluminum enclosure and engineered for maximum flexibility, the FSU supports a wide range of deployment scenarios through configurable analog and digital VectorSeis sensor interfaces.

Hawk autonomous nodal system enables true cableless operations while maintaining superior recording fidelity, long deployment duration, and simplified field logistics.

Key Features

Flexible Channel Configuration

Supports 1, 2, or 3 analog channels plus  3‑component VectorSeis digital interface or 1-channel AccuSeis digital interface, giving field teams a single platform for diverse survey requirements.

Ruggedized for Harsh Environments

Designed to meet or exceed MIL‑STD‑810F standards for temperature, immersion, shock, and transport durability.

Integrated Wireless Communication

Includes Bluetooth and Wi‑Fi, enabling streamlined health checks, diagnostics, and configuration in the field.

Onboard 16 GB Solid‑State Storage

Non‑volatile flash memory for reliable data capture throughout long-duration deployments.

Low Power Operation

Consumes as little as 0.36 W (1‑channel configuration) and is compatible with INOVA’s high‑capacity external lithium‑ion power packs.
