The control calculation portion stores coordinates of a machine reference point of the collimating ranging unit and a direction of a reference collimation of a telescope portion, stores first point group data, stores a direction of a first collimation of the telescope portion oriented from the movement source position toward a movement destination position, stores a direction of a second collimation of the telescope portion oriented from the movement destination position toward the movement source position and a movement distance, calculates and stores coordinates of the machine reference point at the movement destination position with the survey start position as a reference based on the direction of the first collimation, the direction of the second collimation, and the movement distance, and stores second point group data.",
