Abstract
A laser tracking device includes an adjustment device, a telescope, and a drive device. The adjustment device modifies the emission direction of first light wave. The telescope emits the first light wave in the emission direction modified by the adjustment device. The drive device rotates the telescope based on a predicted path of a moving body. The adjustment device provides more precision in modifying the emission direction of the first light wave than in the drive device rotating the telescope. Further, the adjustment device modifies the emission direction to offset the modification of the emission direction caused by the rotation of the telescope from a time when a tracking start condition is satisfied until the moving body is detected.
