Semi-Active Laser guidance Kit is a system that guides a rocket in its terminal flight phase, aiming to reach a spot provided by an external laser designator.

SALK is composed by two main different modules: the Electro-Optical Spot Detection (EOSD) and the Guidance and Control Section (GCS).

The EOSD acts as the main sensor. This module is composed of the Objective for Laser Spot Detection (OLSD), which is the optomechanical set that contains the optical objective for the detection of the laser spot, and the Laser Spot Processor Unit (LSPU), which comprises a segmented quadrant position-sensing detector and the signal processing electronics.

The GCS integrates the electronics, actuators and control surfaces needed to process the information from the EOSD and to modify and correct the trajectory of the rocket in order to reach the objective.

SALK is designed to be integrated on different rockets with a calibre of 70 mm. In order to keep independence of the rocket it is mounted on a mechanical adaptor meant for this purpose.
