Provided is an antenna system for satellite communication and a method for tracking satellite signals using the same, in which moving vehicles or vessels can perform a satellite multimedia communication. The method for tracking a satellite signal using the antenna system includes the steps of: a) setting a satellite signal reception environment by performing an electronic tracking in the elevation direction through an electronic beam steering control and performing a mechanical tracking for driving a rotating element in an azimuth direction; and b) stopping a drive of the rotating element in the azimuth direction, and setting a satellite signal transmission environment by using the satellite signal reception environment. According to the present invention, since both one-dimensional phase array control of the elevation and azimuth and one-dimensional mechanical control are used, it is possible to provide the economical and effective system compared with two-dimensional phase array antenna.
