The Antenna Control Unit (ACU) is a unit controlling the communication subsystems and antennas for air (UAV, helicopter, aircraft), sea and land platforms and positioning the antenna precisely on two axes, and providing its communication with all subunits and surrounding units. The ACU has the target tracking capability with 3-D precise space tracking algorithms. The ACU also has the capability of processing the messages received over the external serial and Ethernet interfaces and then switching and filtering them into different interfaces.
