DirtMate RTK 101: Centimeter-level positioning for grade checks, stakeout, and in-cab guidance

What RTK actually means

RTK stands for real-time kinematic: a GPS positioning method that uses a correction stream from a base station to deliver centimeter-level accuracy in real time.

Standard GPS is accurate to a few meters at best. RTK corrections tighten that down to two to three centimeters. That’s the kind of accuracy that matters when you’re checking whether a pad is at the right grade, whether a pipe was installed at the right depth, or whether a berm is where the design says it should be.

How corrections work: base and rover, simply explained

DirtMate RTK uses a base-and-rover setup to deliver its accuracy. Here’s what that means in plain English.

You can also connect DirtMate to an existing correction network (like a NTRIP service or regional CORS reference station) if your region already has one set up. Either approach works. You don’t need to replace your existing correction source.

What accuracy actually looks like

Two real-world validations worth knowing before you evaluate.

For earthwork grade checking, those tolerances are well inside what the work requires.

Common questions

Does it replace our existing NTRIP or CORS network?

No. DirtMate RTK connects to your existing NTRIP or CORS network if you have one. You can also use one DirtMate as a base station to provide corrections to others on site, useful for sites without network coverage.

Can operators use it, or just surveyors and foremen?

All three. The in-cab view is designed specifically for operators. Grade check and point capture workflows are built for foremen and site supervisors. None of these require a surveyor’s competency to operate safely.

What happens if signal drops on a deep cut?

DirtMate logs locally and reconciles when the connection returns, so data isn’t lost. For sites with chronic dead zones, one DirtMate can act as a local base to extend coverage where NTRIP can’t reach.

Does it work alongside our Trimble rovers?

Yes. DirtMate RTK and traditional survey rovers are complementary. The rover stays on boundary surveys, control work, and complex alignment stakeout. DirtMate RTK handles the self-serve grade checks and field positioning your survey crew would otherwise have to mobilize for.

Is it a good fit if we’re new to DirtMate?

Yes. DirtMate RTK is available both as an upgrade to existing DirtMate customers and as part of a combined package for teams new to DirtMate. The combined platform gives you machine tracking, telematics, and RTK grade checking in one subscription.
