Alignment control device |
摘要 |
A tracking device comprises a cam-driven actuator arm by which the declination of an earth station dish is caused to vertically oscillate with a sidereal day cycle. In a second embodiment, the tracker comprises a constant velocity joint interposed between the satellite dish and the elevation frame of the antenna mounting structure. The rotation of the constant velocity joint over a sidereal day cycle will result in tracking of the figure eight path.
