Sea Tel DAC-03 Tracking Antenna Controller

Sea Tel DAC-03 Tracking Antenna Controller

The DAC-03 Antenna Control Unit (ACU) communicates via an RS422 serial data link with the Pedestal Control Unit (PCU) located on the antenna. For unlimited azimuth pedestals, the RS422 link is coupled to the PCU via RF Multiplexers and is conducted across one of the ADE/BDE coaxial cables. The Pedestal Control Unit stabilizes the antenna against the ship’s roll, pitch, and turning motions. The DAC-03 ACU is the operator interface to the PCU and provides the user with a choice of positioning commands to point the antenna, search commands to find the satellite signal and tracking functions to maintain optimum pointing
