Auto-Tracking Antenna Control Unit is designed to meet the requirements of telemetry and radar applications for tracking high speed moving objects like missiles, aircrafts, and launch vehicles. The Antenna Control Unit is suitable for slow moving objects like satellites and time based positioning applications. The Antenna Control Unit generates scan signals to receive and demodulate error signals from mono pulse tracking feed, to automatically track high velocity moving targets. Auto-Tracking Antenna Control Unit is strong and rigid in construction and requires minimal maintenance.
