  • Patent number: 10234532
    Abstract: A rotation determiner determines whether an antenna azimuth (AZ) angle rotates beyond a rotation range within a predetermined time based on a predicted orbit value. When the antenna AZ angle rotates beyond the rotation range, an orbit determiner determines whether an estimated satellite position is within a drivable range that the AZ angle rotates from a reference value beyond the rotation range. When the AZ angle rotates beyond the rotation range and the estimated satellite position is within the drivable range, three-axis control is executed, and the AZ angle is kept at a predetermined value. When the AZ angle rotates beyond the rotation range and the estimated satellite position is not within the drivable range, or when the AZ angle does not rotate beyond the rotation range, two-axis control is executed.

  • Patent number: 9912051
    Abstract: A vertical axis driver drives a vertical axis for azimuth angle tracking. A horizontal axis driver drives a horizontal axis for elevation angle tracking. A cross horizontal axis driver drives a cross horizontal axis to which an antenna is attached, that is rotatable around an axis orthogonal to the horizontal axis. An arithmetic processing controller generates a drive signal of a constant azimuth angle the vertical axis when a maximum elevation angle of the antenna is greater than or equal to a set angle in a path of the target object in a single time of continuous tracking. When the maximum elevation angle of the antenna is less than the set angle in the path of the target object in the single time of continuous tracking, the controller issues a drive command of an azimuth angle direction to the vertical axis.
