Robotic Machine Control

GPS+ and MMGPS+ systems work extremely well when machines are capable of receiving GPS satellite signals, but what happens when the jobsite does not have visibility to open sky? Working between buildings or in heavy tree coverage can limit the performance of a 3D-GPS control machine. In these situations Topcon's LPS-900 (Local Positioning System) is the ideal system for guiding your machines.

Based on our popular 900/9000 robotic total station platform, the LPS-900 offers high accuracy position control over your entire site, to within a few millimeters. Topcon's new robotic total stations utilize the patented XTRAC technology to track machines at speeds up to 35 MPH. Machine and blade position is updated 20 times per second, fast enough to meet the tightest jobsite specs. This speed and accuracy makes difficult and complex sites easy to grade.

Robotic Machine Control

Switching existing GPS+ systems to LPS-900 is simple. Put up the total station on a control point, place a 360° prism on the vibration pole and a RS-2 radio in the cab and you're ready to go to work. The robotic total station locates the 360° prism and sends the X, Y, Z position of the cutting edge to the machine via radio link. The operator can now work as before, but with very high accuracy. Obstructions to the sky no longer hinder your work or slow you down. Whatever the conditions are at the job, Topcon LPS-900 can help you get it done fast and accurately.

Sensor Freedom

Sensor Freedom

Topcon has a long history of leadership in machine control. We build a wide variety of sensors, each of which has applications where it shines out as the best choice. Want to use a laser? A sonic system Need the high accuracy of a total station? Want to blend your sensors on a single the sensor type(s) best suited to your application, plug them in to your Topconmachine control system, and off you go. Topcon's component-based system takes it all in stride, so you can too.
