Abstract. The problems of the construction of the ship antenna unit (SAU) for receiving information from the satellite communications system (SCS) on the basis of reflector antenna are discussed. These problems include the development of the mathematical model and the generalized control algorithm in terms of pitching of the ship. Permanent functioning of the SCS channels is ensured by the fulfillment of two requirements: directing of SPACECRAFT (SC) and receiving signals with a given polarization. To implement these requirements in SAU it proposed to use three-axis pedestal with the axis "of the mirror tilt" and adaptation of the polarization basis of the antenna by turning the antenna-waveguide antenna feed. The correlation between the kinematic parameters of the drives SAU and antenna-waveguide antenna feed with parameters of SPACECRAFT motion and rolling of the ship are investigated On the basis of numerical simulation. The practical implementation of SAU are discussed.
