SENTINEL MLRF X

The SENTINEL MLRF X is a ruggedized, multi-sensor thermal imaging and observation binocular designed for conventional forces, special operations forces, and homeland security units operating in the High North and Arctic environment. The system delivers ISR, target acquisition, and situational awareness across day, night, and degraded visual environments — including polar darkness, white-out, blowing snow, and the contested electromagnetic conditions characteristic of Arctic operations.

A 640 × 512 uncooled thermal imaging sensor provides long-range detection and classification under all weather conditions, while an AI-enabled processing engine analyzes live video in real time to automatically detect vehicles, vessels, and personnel — accelerating threat identification across featureless Arctic terrain and maritime littoral zones. A complementary direct view optical channel provides 7× magnification, 7° field of view, and ±5 SD visual acuity to support sustained observation during extended High North patrols. The system incorporates an eye-safe laser rangefinder with 10 km ranging capability, digital magnetic compass, and embedded GPS, enabling real-time range, azimuth, and target location in GPS-degraded and magnetically anomalous Arctic environments. This sensor-to-decision capability supports maritime domain awareness, call-for-fire, and network-enabled operations aligned to Arctic experimentation objectives. Engineered to MIL-STD durability standards, the SENTINEL MLRF X is optimized for 24/7 continuous operations in the austere and strategically contested High North.

 

 

 

  • Long-Range Thermal Detection & Recognition
    Equipped with a 640×512 uncooled thermal sensor, the SENTINEL MLRF X delivers reliable target detection and classification in total darkness, harsh weather, and degraded visual environments.
  • AI-Enhanced Automatic Threat Detection
    An integrated AI processing engine analyzes live video in real time to automatically identify vehicles, vessels, and personnel — accelerating decision-making in complex operational environments.
  • Integrated 10 km Laser Rangefinder & Target Location
    Features a Class I eye-safe laser rangefinder with up to 10 km capability, combined with GPS, Galileo GNSS, and digital magnetic compass for precise target localization and situational awareness.
  • Multi-Sensor Fusion for Day & Night Operations
    Combines thermal imaging with a high-performance direct-view optical channel and day camera, including multiple image fusion modes for superior observation across all lighting conditions.
  • Ruggedized for Extreme Arctic & Military Environments
    Engineered to MIL-STD durability standards and optimized for Arctic operations, the system performs reliably in temperatures from -30°C to +60°C, including white-out, blowing snow, and contested electromagnetic environments.
  • Built for Continuous ISR & Tactical Operations
    Designed for 24/7 surveillance, reconnaissance, and target acquisition missions with onboard recording, multiple connectivity interfaces, tripod mounting capability, and up to 6 hours of continuous operation.
