Sokkia Announces “DX-105AC+” – A New Robotic Total Station

Sokkia Corporation announces a new robotic total station, DX-105AC+, designed to provide a feature-packed solution for one-person operations.   Robotic functionality is also now available for standard model DX total stations through an auto tracking firmware upgrade.

“The DX robotic solution sets the standard for design, performance and price at the entry level of the robotic total station market,” said Leighton Davies, TEP business manager survey products.

The new DX Auto Tracking Kit comes on a USB memory stick and can be installed on any standard DX unit. “The upgrade can be made easily at any time–a unique, and ideal solution if you have not used robotic total stations, but wish to make the switch,” Davies said.

“Add a 360-degree prism and MESA data controller with MAGNET™ v2.0 and you have the perfect entry-level robotic package,” Davies said.

The DX total station series features long-range Bluetooth® communications, class-leading tracking performance and an easy-guide light system for prism reacquisition.  Additionally, the series includes Direct Aiming™ auto-collimation technology, TSshield™ advanced security and maintenance technology and MAGNET™ integrated software.

Davies said, “The DX comes with Sokkia’s patented RED-Tech reflectorless measurement system and advanced angle measurement system, both industry-leading technologies.”

The DX series is ideal suited for jobs that require the highest accuracy with simple operation. Its Direct Aiming technology, featuring a new intelligent algorithm that automatically aims to the prisms, ensures precision readings and layout are achieved.

It is also ideal for dim or dark conditions where the prism is difficult to locate. Whatever the job requires and wherever operators must go, the DX makes your job done easier and faster with accuracy you can trust.

Key DX features include:

  • Superior Auto Pointing Technology
  • MAGNET Field on-board application software
  • Advanced Angle Measurement System
  • RED-Tech advanced reflectorless measurement
  • Long-Range Bluetooth® wireless communication
  • TSshield security, tracking, and remote diagnostic support
  • Available in 1, 2, 3, and 5 second models

    I had used total station DX 105 During the night working all night it was very good, no any problem even far distanced like 500 meters, use auto motorize it will find by it self accuracy 1mm, so I like it very much, good instrument .
