The coordinates and orientation of a total station can be determined by using common points, i.e. pointssurveyed both by total station and RTK (Real Time Kinematics) GPS. In this paper we use a trial anderror method to analyse how the number and distribution of common points affects the precision of thetotal station establishment. It was found that a reasonable number of common points is 10 – 30, and thatthese should be distributed around the total station on a half circle. The radius of the half circle doesnot significantly affect precision of horizontal and vertical positions; it affects only orientationprecision. Therefore we suggest locating most of the common points close to the total station and a fewof them at longer distance.
