Abstract
A surveying system comprises a surveying machine (11) which is disposed at a reference point (A) and a reflecting mirror (5) which is disposed on the side of a target point (B). In this surveying system, a signal-light projecting device (16) for projecting a beam of signal light (P3) onto the surveying machine (11) is disposed on the side of the target point (B), and a rough-direction detecting device (20) for detecting roughly a direction in which the signal-light projecting device (16) is located by receiving the beam of signal light (P8), and a precise-direction detecting device (21) for detecting precisely the direction in which the signal-light projecting device (16) is located by receiving the beam of signal light (P3) are disposed on the side of the surveying machine (11).
