Paper Abstract

A two-step method is proposed to orientate the Total Station (TS) precisely with the help of a Fiber Optic Gyro (FOG), in which another control point is not needed. The operation methods have been introduced, the formula to calculate the azimuth of the traverse axes of TS has been derived, and the accuracy of the orientation has been calculated. As long as that the projections of install error on both the vertical and horizontal planes are less than 1°, the systematic error and the installation error can be eliminated or compensated very effectively. Correspondingly, the precision of orientation is mainly influenced by the random error arisen in the FOG observations and is accurate enough for some daily surveying works.
