IS - 3 Imaging Station

The world’s first long-range robotic scanning instrument, the IS-3!
The power, accuracy, and speed of a Total Station with the auto-scanning capabilities of a Laser Scanner; Topcon’s IS-3 takes material management, as-built design, and structural/environmental monitoring out of the clouds and puts it at your fingertips…

A new way to scan

Topcon’s IS-3 combines the best of two worlds, advanced imaging and high-accuracy surveying, incorporating real-time field imagery with spatial data. The IS-3’s powerful functionality is controlled using Topcon’s exclusive ImageMaster™ software that produces “photography with dimension”, a revolutionary and cost effective alternative to laser scanning.

Long Range Scanning

Nobody can provide the combination of laser scanning and robotic surveying like Topcon with the IS-3. The long non-prism (6,500’ (2,000m)) robotic instrument now can scan long ranges as well. Mining and monitoring applications can be accomplished with the IS-3.

Remote Networking

The IS-3 has WLAN capability and can be controlled remotely. Imagine sitting in the comfort of your office or vehicle and being able to scan, measure, control, and see what the IS-3 is seeing.

Touch Drive - Turn and select a point on screen

Simply touch the screen image to drive the cross hairs where you want. For the highest degree of data accuracy, clarity of image is key. That’s why Topcon incorporates telescopic zoom with a LCD. Using the telescope, pinpoint features to be measured or monitored precisely up to 6,500’ (2,000m) away.
Does more than a robotic instrument! Does more than a laser scanner!
The Topcon IS-3 combines the power of both a laser scanner and a robotic instrument
into one superior long-range, imaging robotic system.

How it Works

Topcon’s IS-3 features dual digital imaging cameras providing a color, real-time image on the touch LCD display.

To define a scan area, simply tap the image display, or for uniform measurement of an area, select the grid feature. The IS-3 “locks” these points to their exact position on the image, even when the instrument is rotated.

Once all points to be measured are chosen, the IS-3 performs a reflectorless measurement of each point.

A Robot at Heart…

The IS doesn't forsake its robotic roots. The IS has all the features of our GPT-9000A robotic total station and more.

Our 9000A series robotic system features sophisticated technology unique to Topcon– our one-touch quick lock feature that set the standard in robotic target acquisition has taken another step forward, with the sleek new RC-3 system. All 9000A series robotic systems offer reflectorless measurement superior to any other instrument available – capable of precision measurements at a mind-boggling 2000 meters! Packed with a wide variety of advanced technologies, the Topcon GPT-9000A series robotic total station demonstrates why Topcon continues to be the world's leader in precision survey instrumentation:

  • Innovative, completely cable-free system design
  • Superior X-TRAC™ Quick-Lock tracking technology
  • Full-color, graphical Windows Mobile instrument & field controller interface
  • The most advanced, longest range, and most powerful reflectorless technology available
  • Integrated interference free 2.4 GHz SpSp robotic data communications

The X-TRAC 7 robotic system upgrade is now available for the IS instrument. This enhancement to firmware and software affects the robotic tracking, quick-lock, radios, and data collector performance.
