Document Type and Number:
WIPO Patent Application WO/2023/120848
Kind Code:
A1
Abstract:
A satellite antenna positioner having a predictive maintenance function, according to an embodiment of the present invention, relates to a satellite antenna positioner having a predictive maintenance function, which supports an antenna and is configured to orient the antenna on the basis of a received satellite signal, the satellite antenna positioner comprising: a first motor which generates driving power for adjusting the elevation of the antenna; a first gear which rotates the antenna about a first axis while reducing the rotational speed of the first motor; a second motor which generates driving power for adjusting the azimuth of the antenna; a second gear which rotates the antenna about a second axis perpendicular to the first axis while reducing the rotational speed of the second motor; a control module which controls the first motor and the second motor on the basis of the sensitivity of the received satellite signal; and a predictive maintenance module which monitors whether at least one of the first gear and the second gear is abnormal.
