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.
