Abstract:
A survey system for transmitting guide light for instructing the direction of a target, the guide light having a wide range with small power. The survey system includes a target having a recursion reflector for reflecting light and a survey apparatus having an automatic collimation device for automatically coinciding the collimation axis of the recursion reflector with that of a telescope. The target includes a guide light transmitter for emitting guide light and scans a fan beam that is wide in the horizontal direction and narrow in the vertical direction in the vertical direction as guide light. The survey apparatus includes a direction detector for receiving guide light and detecting the direction of the guide light transmitter and also includes a collimation preparing device for turning the telescope roughly to the recursion reflector based on an output signal from the direction detector prior to commencing the automatic collimation.
