Guided Weapons
Centred on the guidance & control unit, Digitron develops and produces the core electronics of guided-weapon systems — guidance data receivers, actuation controllers, anti-jam GNSS RF assemblies, fuze TDD signal processors, and seeker frequency synthesizers and servo controllers. We also supply the command & communication device and code loader that support weapon employment, and guidance & control units for aerial target drones.
Guidance & Control Unit (GCU)
The brain of the round: it links the forward subsystems — seeker, IMU, guidance data receiver — with the aft subsystems — actuation unit, anti-jam GNSS, fuze — and controls every phase of flight.
Guidance & Control Unit — Operating Concept
Inside a guided-weapon system the guidance & control unit exchanges power, commands and target data with the forward and aft subsystems, controlling the round through every phase of flight. The diagram magnifies the position of the unit within the round and shows the signals exchanged with each subsystem.
