Title:
偏心傾斜位置機構を有するアンテナポジショナ
Document Type and Number:
Japanese Patent JP7411862
Kind Code:
B2
Abstract:
Methods, systems, and devices are described for antenna positioning with an eccentric tilt pointing mechanism. For example, a system in accordance with the present disclosure may include a base structure configured to support an antenna and an antenna positioning apparatus configured to adjust an orientation of the antenna. The antenna positioning apparatus may be supported by the base structure and comprise: an intermediate structure, a positioning system and an actuator. The intermediate structure may be configured to rotate about a first axis. The positioning system may be coupled with the intermediate structure and may be configured to orient an antenna boresight about at least two angular degrees of freedom with respect to the intermediate structure. The actuator may comprise a rotating element, a drive element and an eccentric element. The rotating element may be configured to rotate about a second axis. The drive element may be configured to drive rotation of the rotating element about the second axis. The eccentric element may be coupled with the rotating element and may be configured to rotate the intermediate structure about the first axis when a position of the eccentric element is changed relative to the base structure in response to a rotation of the rotating element caused by the drive element.
