GT Total Station
Bright, Sharp Guide Light
The Guide Light allows operators to instantly recognize the line between the instrument and the stakeout line, with clearly visible Green and Red lights.
RC handle (GT-1000 series)
RC-5 sensor on the handle can be used for auto-prism searching. This allows easy, rapid prism searching regardless of your position.
Trigger key
Just “Rough Aim” and “Press Trigger button” to get precise aiming and measurement automatically and easily.
Jog dial
You can rotate GT with smooth jog dial.
USB available
Serial cable and USB connections can be used (Max:32GB) for data transmission/reception.
Large display
Large and high-resolution WVGA display provides clear visibility under the sun light. Moreover, large size icon improves operability.
Waterproof and dustproof:
IP65 design
Provides protection from dust and driving rain as well as other inclement weather conditions. Operates in temperatures from -20 to +50ºC.
Auto-tracking
Increases power for prism tracking under extreme conditions of frequent interruption or strong reflections.
Even if a prism rock is lost, you can easily rotate GT and reacquire prism with RC-5 and go back to work smoothly.
Auto-collimating
Precise measurement can be done by just “Rough Aim” and “Press Trigger button” without lens focus and other operation. Auto-collimating provides consistent accuracy and speed regardless of operator’s skill levels and condition.
The world's fastest! *
UltraSonic motor and direct drive system!
Accomplished world's fastest turning speed of 180° per second with UltraSonic motor and direct drive system. This also contributes to ultra-slim body.
The world's lightest *
Accomplished weight-saving, 5.7 kg motor drive total station!
GT is a third smaller than any previous Topcon robotic instrument and the same weight as a manual total station — providing easy carrying and set up at a project site.
The world's smallest! *
Redesigned ultra-slim body!
GT is designed by reviewing of the basis and redesigned to the world's smallest total station.
World's first Internetconnected( IoT) total station!*
Integrated cellular modem. Total station now with Internet-connectivity!
GT is fully networked with cellar modem and wireless LAN. This allows direct connectivity to MAGNET® Enterprise and provides you close connection between project site and office staff and managers.
Highest quality in class
Passes various environmental test with Topcon quality!
Tough designed GT, passes impact, vibration, high-temperature, and humidity testing —provides consistent performance at any harsh environments.

*3 Figures when both the elevation and depression angles of the laser beam are within 15º and the instrument is facing the ATP1/ATP1S 360º prism
*4 When using a reflective sheet for Auto Pointing, the size of sheet (10 to 90 mm) must be selected to correspond to the distance being measured. Use smaller reflective sheets for shorter distances. Figures when the Auto Pointing beam strikes within 15° of the reflective sheet target.
