The System

The GradeMetrix Mini Excavator GNSS Grade Control System is packed full of industry-leading technology. What makes it so amazing is that it is also the lowest-cost 3D GNSS system on the market.  Using the FR500 rugged all-in-one GNSS smart antenna and the FDm1 rugged display, you get RTK-level positioning and precise heading on your excavator.   The typical do-it-yourself installation takes 8 hours or less to install and calibrate the system.

The versatile GNSS tracks all signals from GPS, GLONASS, Galileo, QZSS, BeiDou, & The L-Band systems.  The standard way to receive your base station corrections is through the F631 via the internal radio, however, you can also receive your corrections via the built-in cellular modem, or over NTRIP through an accessible RTK network.  All of these modes are standard with all GradeMetrix systems.

Introducing 2.5D Grade Control

The embedded 2.5D function allows you to use the GNSS guidance technology for a vast array of useful applications without the need for 3D files.  Using only a few keystrokes your operator can easily create simple layers, single and dual slopes, trenches, ramps, batters, pads, and even roads just using your GNSS as a reference.  No survey points, local transformations, or projections are needed using the 2.5D features.

Complete 3D Operation

If you do require 3D models, then the Futtura GradeMetrix system works seamlessly with your standard surface and background files.  Load files via the USB port or through cell via email or whatever online file sharing you prefer.  DWG, DXF, TIN, and more.

Visualize the site in real-time, eliminating delays and enabling fast and efficient completion of all site work.
