3D Motor Grader mmGPS

Make mmGPS work for you and be the solution for the challenging jobsites when high precision elevations are required. Precision staking becomes a one man operation with this Topcon GPS system.

Features & Benefits

  • World’s first millimeter accurate GPS system, up to 300% more accurate than standard GPS
  • Laser Zone transmitter provides precise vertical measurement area 600m in diameter, 10m in height
  • Works with existing Topcon GPS+ systems
  • Multiple rover support machine or pole mounted
  • Lower investment – one system works for rough and finish grade
  • Grade to tighter tolerances and eliminate high cost material overruns
  • Finish grade 24/7 even with minimal satellite coverage

Millimeter GPS+ transforms GPS into the perfect tool for blue-topping and other fine tolerance work.

With Millimeter GPS+, the days of lost productivity, using stringlines or running manually off of hubs, are over.  Millimeter GPS+ combines the advantages of laser (multi-user & high vertical accuracy) with GPS (multi-user & 3D) into one versatile and easy to use system.

This patented technology improves grading accuracy up to 300% over existing 3D-GPS machine systems.  Unlike any other laser technology, the PZL-1 transmitter sends out a wall of light 33’ tall and up to 2000’ in diameter. Simply add the PZS-MC machine control sensor or PZS-1 rover sensor to your existing GPS+ system, and watch your GPS vertical accuracy shrink down to numbers you never imagined before.

Need more coverage?

You can link up to four PZL-1 transmitters for a total of 8000’ horizontally and 132’ vertically. Unlike with total stations, multiple machines and man rovers run off one transmitter, there is no limit!
