Total Station

Total Station (TS), is a primary equipment that is commonly used in public surveying. It plays a role in all types of onsite surveying operations, from precision surveying, to reference point surveying, route surveying, plane table surveying, topographical surveying, and land surveying.

TS refers to an optical instrument utilized in the present days that simultaneously measures angle and distance, which are the basic elements of a survey. The actual position of a surveyed new point is obtained based on the angle and distance obtained through TS observation.

The establishment of central piles, etc. in all control points, site boundaries, and road surveying, including road control points, the periodic measurement of the cross-section inside tunnels, surveys on the degree of variation in runways and the enclosing bunds of dams, and measurement of the shape of ground features using TS are carried out. In addition, in GPS observation that is dependent on the satellite signals, measurement using TS is carried out even when sky visibility cannot be guaranteed.
