Active base-tracking multi-antenna system and active base-tracking antenna system for vessel and offshore structure

Abstract

An active base-tracking multi-antenna system and an active base-tracking antenna system for a vessel and an offshore structure are provided. The active base-tracking multi-antenna system may include: a fixing shaft fixed to a fixture on a vessel or an offshore structure; a gimbal unit disposed on a top of the fixing shaft and keep positions of a panning motor and antennas; the panning motor disposed on the gimbal unit and simultaneously rotating the antennas in a left-right direction; and the antennas connected to the panning motor. Therefore, it is possible to always keep the antennas in a stable horizontal position and greatly improve communication quality by adjusting the azimuths and vertical angles of the antennas in real time to an optimal state for communication with a base station.
