APPARATUS FOR CORRECTING TILT ANGLE TO CONTROL STANCE OF SATELLITE ANTENNA SYSTEM

摘要

PURPOSE: An apparatus for correcting a tilt angle to control a stance of a satellite antenna system is provided to maximize the receiving sensitivity by controlling the stance of the satellite antenna system installed at a floating object such as a ship. CONSTITUTION: An apparatus for correcting a tilt angle to control a stance of a satellite antenna system includes a first mixing unit, a gain control unit, and a second mixing unit. The first mixing unit(102) compensates the coulomb damping by mixing the first tilt angular velocity with the second tilt angular velocity. The gain control unit(112) compensates a gain of an output signal of the first mixing unit. The second mixing unit(105) outputs a driving signal to a driving motor by mixing an output of a PID controller with an output of the gain control unit.
