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.
