SUNWAY ATS-120A Total Station

The SUNWAY ATS-120A is a 2″ accuracy total station designed for general surveying, construction and engineering applications. It combines absolute angle encoding, a 30× telescope, reflector and reflectorless EDM, dual-axis compensation and practical field surveying software in a compact conventional total station.

The ATS-120A supports functions such as surveying, stakeout, resection, area and volume calculation, road surveying and reference line or arc operations. Its color TFT display, laser pointing, Bluetooth communication and multiple data transfer interfaces are designed to make routine field work more convenient. RTKSurvey.com supplies the SUNWAY ATS-120A for surveying contractors, engineering teams and surveying equipment distributors.

Why Choose the SUNWAY ATS-120A?

The SUNWAY ATS-120A offers a practical combination of angle accuracy, distance measurement and field surveying functions for projects that do not require a robotic total station. Its reflectorless EDM can help surveyors measure selected points without placing a prism directly on the target, while the dual-axis compensator supports efficient instrument setup and routine field operation.

The straightforward software structure and familiar surveying workflows make the ATS-120A suitable for teams performing boundary, topographic, construction and engineering measurements. With Bluetooth, USB and SD card data options, it also provides flexible ways to transfer and manage survey data in the field.
