Claim Text:
1. A survey system comprising: a guide light emitting optical system that emits a fan-like visible laser light elongated in upward and downward directions as a guide light; a cylindrical part that has a scanning optical system that searches a corner reflector provided on a survey pole and a ranging optical system that measures a distance to the corner reflector; a driving part that rotates the cylindrical part about a vertical axis in a horizontal direction and that rotates the cylindrical part about a horizontal axis; an angle measurement part that measures a direction of the cylindrical part; a first storage part to store the distance to the corner reflector obtained by the ranging optical system and the direction of the cylindrical part as measurement data; a control circuit that controls the driving part, the scanning optical system, and the ranging optical system; and a transceiver part that transmits the measurement data stored in the first storage part to a mobile wireless transceiver at a side of the survey pole, wherein the guide light emitting optical system is rotated about the vertical axis in a horizontal direction together with the cylindrical part; the control circuit controls the driving part to rotate the cylindrical part toward a next setting point; the transceiver part transmits the measurement data stored in the first storage part to the mobile wireless transceiver; and the mobile wireless transceiver includes
