Abstract: The present disclosure obtains a correction value that corrects measurement angle error signals more accurately than conventional methods even in a case where a radio wave signal-to-noise ratio is low, and thus tracks a communication counterpart more accurately than the conventional methods.

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.

Abstract: An antenna control device includes a direction acquirer to acquire a target direction in which a target object to be tracked exists, a coordinate converter to perform conversion into an Y-coordinate which is an angle between the target direction and a plane containing both the zenith direction and a Y-axis fixed horizontally within a rotation range of the vertical axis, and into a X-coordinate which is an angle between the zenith direction and a projection of the target direction projected onto the plane. A drive command value arithmetic processor commands a vertical axis angle value obtained by multiplying the Y-coordinate by a coefficient. The arithmetic processor calculates the command value for each of the horizontal axis and the cross horizontal axis such that difference between the pointing direction of the antenna and the target direction is less than or equal to an allowable value.
