Primary electro-optical sensors including the FLIR/CCD camera and laser range finder/designator will be installed inside a nose mounted Gimballed Payload assembly(GPA) similar to the one on the Nishant UAV. DRDO has developed a nose mounted gyro stabilised sighting system for the ALH, comprising of a high performance thermal imager and Laser Range Finder with a 4 km detection range of a NATO Tank target. Known as the Heliborne-thermal imaging system(HELITIS), it provides a stabilization accuracy of 30 microradians and is intended for target recognition and engagement.
