G3 Technology
GPS + GLONASS + Galileo
Every available signal - today and tomorrow

 Topcon was the first to offer the dramatic increase in performance of GPS+, our unique combination of both the American GPS system and the Russian GLONASS satellite system. Complex technology, but a simple result: unbeatable performance and uptime. Now, you don't need to sit idle waiting for enough satellites to be visible to your machines. You won't need to think about satellites hardly ever, because Topcon is making sure you get the performance you demand. And our new G3 technology reads not only all current satellites, but future systems as well, so that you can buy a system today and get cutting edge performance for years.

Only from Topcon.

Sensor Freedom
Flexible system configurations for every job

Topcon has a long history of leadership in machine control. We build a wide variety of sensors, each of which has applications that make Topcon the best machine control option in the industry. Want to use a laser? A sonic system? Need the high accuracy of a total station? Want to blend your sensors on a single machine? Only Topcon allows what we call Sensor Freedom: you choose the sensor type(s) best suited to your application, plug them in to your Topcon machine control system, and off you go. Topcon's component-based system takes it all in stride, so you can too.

Stakeless Grading
The Topcon Advantage

What is stakeless grading?
What’s the greatest source of delay on your jobs? Placing, and replacing, stakes has been a necessary headache in construction, until now. GPS machine control combines two fantastic technologies, Satellite Positioning and Digital 3D models, so that your machine operators can see themselves moving on the site plan in real time, with cut/fill information constantly displayed anywhere. This gives operators much more information than stakes do, allowing you to work at a much faster rate. And now, one grade checker can work the whole site because the machines are independent. Everyone knows exactly where the machines are and operators have all pertinent job information at their fingertips.

That’s Stakeless Grading!
