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