Abstract
A survey system is made up of a target and a surveying instrument provided with an automatic collimator that automatically collimates the target. The target includes a guide light transmitter that emits guide light, an azimuth angle sensor that detects a direction angle (θA, θB) at which the target is directed, and a central processing unit that sends a rotation command, which includes the rotational direction of the instrument body, to the surveying instrument. The central processing unit determines the rotational direction of the instrument body based on an angular difference (θB-θA) between a direction angle (θA) obtained when the target is caused to approximately face the surveying instrument at the last measurement and a direction angle (θB) obtained when the target is caused to approximately face the surveying instrument at the present measurement.
