Long-Range Stabilized Electro-Optical Surveillance System (LRSEOSS)
Surveillance is the primary building block of situational awareness.
Military, paramilitary, HLS, law enforcement and security organizations require cost-effective, versatile surveillance and targeting systems that are easy to install, maintain and operate, to provide input for their situational awareness picture and support their tactical operations.
Systems and payloads incorporating optical and thermal sensors combined with active targeting measures are currently the norm for cutting-edge surveillance in the air, at sea and on the ground, and are employed in an extensive range of defense, HLS and combat applications.
The ultimate objective of multiple-sensor surveillance systems is versatility – the same system/payload should be able to fulfill as many surveillance and targeting functions as possible: daytime and night surveillance, range measurement and targeting.
Various defense, security and HLS activities such as border defense, vital installation security and coastal defense require permanent or ad-hoc coverage by long-range surveillance systems.
ACS presents LRSEOSS – Long-Range Stabilized Electro-Optical Surveillance System.
LRSEOSS consists of three primary elements: a gyro-stabilized pan & tilt assembly capable of accommodating different sensor combinations (e.g. thermal imagers, daytime cameras and Laser modules); technical infrastructure (cables, converters & interfaces) and a control sub-system (servers, displays and user interface units).
LRSEOSS adheres to the basic principles of reliable operation, simplified maintenance and operation, modular design and superior performance.
The sensor unit of LRSEOSS contains an IR sensor for night operation, a daytime and/or low-light sensor and a Laser module. The Laser module consists of a Laser Range Finder (LRF) and a Laser pointer. A Laser illuminator is optional.
LRSEOSS provides the user with a comprehensive range of surveillance and targeting capabilities: motion detection, target locating & classification, range measurement, target tracking, panoramic displays, video stabilization and image fusion.
Additionally, LRSEOSS features state-of-the-art image processing capabilities: contrast enhancement, color restoration, turbulence mitigation, image sharpening and edge enhancement.
LRSEOSS offers a cutting-edge solution to such defense, HLS and security activities as border area monitoring, intelligence gathering, coastal surveillance and installation/vital infrastructure security.
