Sokkia SX-103T 3" Auto-Tracking Total Station

The Sokkia SX-103T 3″ Auto-Tracking Total Station is a robotic surveying instrument used to measure angles, distances, and the positions of points. With 3-arc-second angular accuracy, it supports land surveying, construction layout, and engineering measurements. It combines electronic angle measurement, laser distance measurement, and motorized target tracking to help professionals collect accurate site data.

Its automatic tracking system follows a compatible prism as the operator moves around the site, reducing the need to aim the telescope manually at each point. With a compatible field controller and appropriate robotic accessories, the SX-103T supports one-person surveying. This allows the operator to collect measurements and perform layout tasks from the prism pole while maintaining a clear line of sight to the instrument.

The instrument’s RED-tech electronic distance measurement system measures to prisms, reflective sheets, and suitable surfaces without a reflector. Reflectorless measurement is useful for observing building faces and other locations where placing a prism is difficult. Its specified reflectorless range reaches up to 1,000 meters under suitable conditions, although surface reflectivity, lighting, and environmental conditions affect performance.

Typical applications include topographic mapping, construction stakeout, reference point establishment, and as-built surveys. Surveyors use the SX-103T to record terrain and structures, locate design coordinates on the ground, and check completed work. Its measurement functions include coordinate measurement, resection, offsets, remote elevation measurement, and area calculation, supporting a variety of field tasks.

Built for outdoor use, the SX-103T features IP65 dust and water resistance, a color display, internal storage, and Bluetooth Class 1 communication with compatible controllers. Dual-axis tilt compensation helps correct small instrument tilts during measurement. These features combine practical field operation with automated aiming and tracking to reduce repetitive work and improve surveying efficiency.
