Abstract
A reflector provided on a land is automatically collimated in such a way that it always comes to the center of the field of view of an automatic tracking type measuring apparatus provided on a platform. When the platform moves vertically or horizontally in this state, the reflector moves within the field of view. Then, a drive signal is supplied to a servo system to cause the reflector to come to the center of the field of view. Based on data measured by the apparatus, the platform is positioned.
