The system

A new class of tactical detection for denied environments.

A star-topology network of seismic sensors with on-device CNN — the AI firewall keeps the radio dark for false triggers. Verified alarms relay to the GBS over 869 MHz LoRa, then onward to a rugged operator terminal. Three of the four kits share one GW core PCB and firmware — fewer parts, one certification path, one OTA pipeline.

Components

Four hardware units. One operational kit.

Every kit ships complete. Sensors, base stations, deployment payload, and operator terminal. The GBS, SDCI, and Mobile Terminal are all built on a single shared GW core — one PCB, one firmware codebase, one BOM line.

Detection

Three threat classes. Validated ranges.

The on-device CNN is trained against 14,000+ hours of field seismic and acoustic data across diverse terrain. Ranges below are minimum guaranteed values — not best-case marketing.

Sovereign design

Your network. Your keys. Your terrain.

Defense systems that depend on vendor clouds are not sovereign — they are leased. dot SAGA is engineered around the inverse: nothing leaves the customer perimeter unless the customer routes it there.

S-01

No Phone-Home

Req 005 by design: zero transmission of user or operational data to the manufacturer or any third party. The optional LTE / NTN backhaul on the GBS is customer-controlled and disabled by default. No vendor cloud anywhere in the stack.

S-02

Customer-Held Keys

All operational keys are customer-provisioned and customer-rotated. Firmware is signed by Contractor PKI; the bootloader rejects unsigned images. Operational crypto material never leaves the customer perimeter.

S-03

GNSS-Denied Operation

The SDCI injects each UGS with its drop position at the moment of deployment, so an absolute coordinate frame is preserved even with zero satellites. Under GNSS jamming, the GBS reconstructs mesh geometry via LR1120 ToF + RSSI ranging.

S-04

Off-Grid by Design

Sub-GHz LoRa in the ETSI 869 MHz band, LBT-gated, +22 dBm. UGS holds ≥ 30 days on a single 2000 mAh cell; GBS holds ≥ 5 months on a 7.0 Ah PRC pack. No backhaul required to operate the network.
