NERIO-ULR is a state of the art modular Electro-Optical (EO) Surveillance, Threat Acquisition (STA) and Reconnaissance system designed to satisfy a broad range of current and emerging customer requirements.

These include:

  • Border security and Critical National Infra-Structure protection
  • Mobile STA and Reconnaissance
  • Coastal surveillance
  • Air Defense and Counter-UAS

NERIO-ULR integrates world-class EO sensors as part of a fully flexible payload configuration together with a gyro-stabilized director mechanism enabling capability, cost and performance to be optimized according to specific customer needs. Utilizing the Horizon Thermal Imaging (TI) camera for provision of a 24hr operational capability, NERIO-ULR combines an 11° to 0.9° zoom field-of-view high definition (HD) TI with a 360° x ±50° system field of regard.

In addition to the Horizon camera, the standard NERIO-ULR sensor payload configuration includes a high-definition color day TV camera with a compatible zoom field of view and optional, eye-safe Laser Rangefinder (LRF) to supplement the surveillance capability and enable threat identification and geospatial location.

The combination of high definition imaging performance, sightline stability and field coverage enables customers to conduct surveillance acquisition operations from short to very long-range with a single EO system asset.

The modular payload and communication architecture of NERIO-ULR enables the Day TV Camera and LRF solutions to tailored to meet specific customer performance, cost and capability needs. Additional special to role modules, e.g. illuminators, dazzle sources and GPS receiver, can also be offered to meet specific operational needs.

Performance of the Horizon TI camera enables the identification of threats at ranges typically beyond the effective range of the threat, enabling early counteraction to be initiated.

NERIO-ULR is designed to facilitate use in direct mounting to platforms, masts or static tower mounted applications. The Horizon TI incorporates a long-life cooling engine enabling extended maintenance free operation whilst the design of NERIO-ULR enables ready access to the cameras for ease of removal and reinstallation when required.
