Specs
Technical specifications.
| Spec | Pathfinder Unattended Ground Sensors (Mini / XL) | GSE-DD Dual PIR Direction-Detection Sensor |
|---|---|---|
| Sensing modality | Seismic — human footstep and off-road vehicle detection with intelligent machine-learning classification algorithms | Dual passive infrared (PIR only) |
| Footstep detection radius | up to 10 (seismically quiet environments, proper emplacement) m | — |
| Light off-road vehicle detection radius | up to 20 (ATVs, dirt bikes) m | — |
| Transmission range | typically up to 10 (terrain dependent; no gateways, repeaters or relays; elevated receiver antenna greatly increases range) km | — |
| Radio versions | Low-power FCC-approved radio (up to 1 km) or high-power radio (up to 10 km); factory set at time of order | — |
| Operating frequencies | Six regional options covering US/Canada, EU, Africa, India, South Korea and South America; factory set by deployment location | — |
| Transmit frequency (US datasheet variant) | 916 MHz at 0 dBm output; FCC waiver available to 20 dBm for certain domestic applications | — |
| Mini — dimensions | 2.6 in diameter x 2.2 in height | — |
| Mini — weight | 0.5 lb | — |
| Mini — batteries | 2 x 3.6 V lithium-ion (embedded) | — |
| Mini — battery life | up to 6 months | — |
| XL — dimensions | 2.6 in diameter x 4.75 in height | — |
| XL — weight | 1.0 lb | — |
| XL — batteries | 8 x 3.6 V lithium-ion (embedded) | — |
| XL — battery life | up to 24 months | — |
| Current draw | <2 uA off; <600 uA on; 250 mA peak during transmission | — |
| Battery-life basis | No more than 50 alerts/day in moderate temperatures; extreme high/low temperatures reduce battery life | — |
| False-alarm discrimination | Rain-filtering algorithms; discriminates small animals (dogs, groundhogs); occasional false alarms for large quadrupeds (horses, cows) | — |
| Link architecture | Line of sight, non-line of sight and beyond line of sight capable; no internet required | — |
| C2 integration | Seamless integration with Tactical Assault Kit (TAK); camera slew-to-cue and UAS fly-to-cue via ARA interface control document (ICD) | — |
| Scalability | Single facility to large areas (square miles); additional sensors integrate seamlessly into an existing kit | — |
| Export classification | ECCN 6A999.a under US Export Administration Regulations; export licence may be required depending on destination, user and end use | — |
| Coverage | — | Two separate paths monitored simultaneously, with direction of travel for vehicles or pedestrians |
| Radio | — | Long-range VHF with adjustable RF output power |
| Battery life | — | 1 year |
| Sensitivity | — | Independently configurable per sensor channel |
| External input | — | Configurable connector for optional contact-closure sensor types |
| Enclosure | — | Rugged compact fiberglass-reinforced polycarbonate with continuous poured-foam gasket |
| Security | — | Built-in tamper sensor |
