Precision Weapon Guidance System

The Compact I²R Seeker product is a precision guidance solution giving even small caliber weapons the capability to detect and track targets using high-performance uncooled infrared imagery and wide-angle sightline steering and stabilization in a very compact and affordable package.

In comparison with an equivalent conventional gimbal configuration, due to its unique design, the Compact I²R Seeker can achieve an approximately 30% reduction in caliber size, whilst maintaining high performance.

The complexity and dynamics of the modern land battlefield and short-range air defense scenarios place challenging demands on guidance systems for precision attack weapons, in particular for compact and low-cost systems. The requirement for highly target-selective and accurate terminal guidance across a broad range of scenarios cannot be achieved by GPS/INS, commanded, or designated line-of-sight systems alone.

Compact I²R Seeker builds upon Leonardo’s world-leading electro-optical seeking capabilities and has been developed to meet the increasing demand for affordable
and compact high precision-guided weapons.

The Seeker sensor, with its high-performance detection and tracking algorithms, is designed for compatibility with future surface or air-launched guided weapons and for the prosecution of modern battlefield and short-range air defense threats.

The Compact Seeker is equipped with a number of sub-modes, enabling the seeker to work with customer-developed detection and tracking algorithms or to retain Leonardo’s high-performance algorithms.
