SATELLITE TRACKING MODE-SELECTABLE SATELLITE ANTENNA SYSTEM
First Claim
1. A satellite tracking mode-selectable satellite antenna system comprising an antenna unit installed in a mobile body configured to receive a satellite signal, a motor unit configured to rotate an oriented direction of the antenna unit, an outdoor unit (ODU) configured to drive the motor unit to orient the antenna unit toward a satellite, and an indoor unit (IDU) configured to control the ODU to orient the antenna unit toward the satellite, the system further comprising:
- a gyro sensor unit detachably installed in the mobile body and configured to sense motion of the mobile body,wherein the IDU is configured to selectively drive one of (1) an in-motion mode of tracking and acquiring an initial position of the satellite, continuously tracking a position of the satellite based on information regarding the motion of the mobile body sensed by the gyro sensor unit and controlling the rotation of the antenna unit based on the continuously tracked position, and (2) a positioner mode of tracking and acquiring the initial position of the satellite and then fixing the oriented direction of the antenna unit.

Abstract
A satellite tracking mode-selectable satellite antenna system is disclosed. In one embodiment, the satellite antenna system includes an antenna unit installed in a mobile body for receiving a satellite signal, a motor unit for rotating an oriented direction of the antenna unit, an outdoor unit (ODU) for driving the motor unit to orient the antenna unit toward a satellite, and an indoor unit (IDU) for controlling the ODU to orient the antenna unit toward the satellite. The satellite antenna system further includes a gyro sensor unit detachably installed in the mobile body for sensing motion of the mobile body. One embodiment of the invention is capable of selecting an in-motion mode of tracking and acquiring the initial position of a satellite and then continuously tracking the position of the satellite, or a positioner mode of tracking and acquiring the initial position of the satellite and then fixing the oriented direction of an antenna.
