PRECISE E2 display, dual IMU sensors, and dual GNSS antennas

Machine Guidance

Dig to Grade, Guided in Real Time

Centimeter-level bucket guidance for excavators: install it in an afternoon, learn it in about 30 minutes, and start cutting to design without waiting on a survey crew, on CAT, Komatsu, and Hyundai excavators.

See It In Action

E2 in the Field

PRECISE E2 is a 2.5D excavator guidance system that shows the operator, in real time, exactly where the bucket is relative to the target grade, so a single operator can dig to design without a survey crew. E2 guides; it never drives the hydraulics or bucket.

Challenge

On most excavation sites, the operator can't see the design target, only the ground in front of the bucket. To know if a cut is deep enough or a slope is at grade, crews traditionally stop the machine, call in a surveyor or grade stake crew, measure, and adjust, repeating until it's right. That means idle machine time, dependency on other people's schedules, and a real risk of over-digging or under-digging when nobody is available to check. On top of that, a lot of guidance systems are complicated enough that adopting one becomes its own project: new software to learn, a specialist install, a learning curve that eats into the productivity gain it's supposed to deliver.

Solution

E2 combines dual GNSS positioning and dual IMU attitude sensing to calculate the exact 3D position of the bucket edge in real time, and displays the live gap between the current bucket position and the target elevation or slope directly on an in-cab touchscreen. It's built to be adopted quickly: about 2 hours to install and calibrate with a single operator and common tools, a single button to start, and roughly 30 minutes for a new operator to learn to run it.

Value

The operator sees the number on screen instead of waiting for someone else to measure. Fewer stoppages, less rework from over- or under-digging, and consistent results even when different operators run the same machine, without the adoption cost of a complicated system standing between you and that result.

Key Benefits

Why E2

Dual GNSS-IMU Bucket Sensing, Multi-View Display

Real-Time Bucket Position and Grade Deviation

The operator always knows exactly how much material is left to remove, without stopping to call for a check, reducing idle time and first-pass errors and making the cut easier to judge on slopes and trenches than a single number would.

Dual GNSS receivers fix the machine's position and heading; dual IMU sensors track boom, arm, and bucket angles in real time. The onboard computer combines both data streams to calculate bucket-edge position and compares it against the reference point and design values the operator sets, shown from multiple on-screen viewing angles.

30-Minute Learning Curve, Broad Excavator Compatibility

Learn It in 30 Minutes, Run It on Swing-Boom and Offset-Boom Excavators

A new operator isn't sidelined for days learning a new system, and a fleet doesn't need to standardize on one excavator type to use E2 across its machines.

2-Hour Single-Operator Install

Install and Calibrate in About 2 Hours, One Person

A machine can go from unguided to guided in an afternoon, without scheduling a specialist installer or taking the excavator out of rotation for days.

One-Operator In-Cab Guidance

One-Man Excavation, No Layout Crew

Frees up survey labor for other tasks and removes the wait time between digging a bit and checking the result.

Because the target and current position are both visible in the cab, the operator can dig independently without a surveyor setting stakes or a second person checking depth.

Reduced Crew Dependency

Fewer People, More Cuts, Lower Cost per Job

Lower labor cost per job and more billable digging time per shift; PRECISE does not publish a fixed productivity percentage because actual gains depend on site conditions and how the crew was working before.

By removing the need for a dedicated survey or stake-check crew and keeping the machine cutting instead of waiting, E2 is reported by PRECISE field testing to meaningfully increase operational productivity compared to unguided digging.

Applications

Where It's Used

Trenching: track trench depth and alignment continuously without repeated stake checks.
Slope building and trimming: hold a consistent slope angle across long runs of cut or fill, including pond and embankment slopes.
Foundation and basement excavation: manage staged, layered digging with a consistent reference.
Channel clearing and fine grading: finish to design elevation without over-cutting and re-filling.
Ground leveling: hold a single target elevation across a leveling pass without repeated grade checks.
Road construction: guide subgrade and formation-level cuts to design elevation before paving layers go down.
River dredging: maintain a consistent channel depth and slope during dredging work.
Farmland leveling and ridging: hold consistent field elevation or ridge height and spacing across long agricultural passes.

How It Works

From Setup to Result

1

Set the Reference

The operator establishes an RTK reference point and enters the target depth, slope, or design line for the current task, then starts the system with a single button press.

2

Sense the Machine

Dual GNSS antennas fix machine position and heading; dual IMU sensors on the boom, arm, and bucket track every rotation in real time, including movements that happen out of the operator's direct line of sight.

3

Calculate Bucket Position

The onboard system continuously combines GNSS and IMU data to compute the real-time 3D position and attitude of the bucket edge, with bucket dynamic attitude accuracy of 0.2°.

4

Display the Deviation

The 10.1" sunlight-readable touchscreen shows the live gap between the current bucket position and the design target, from multiple views, so the operator can adjust the next pass accordingly.

5

Dig to Grade

The operator uses the on-screen guidance to make corrections: E2 informs the decision, the operator executes it.

FAQ

Common Questions

E2 is a guidance system, not an automatic control system. It does not move the bucket or control the hydraulics. It continuously shows the operator the real-time gap between the bucket's position and the design target (depth, slope, or trench line), and the operator makes every cut manually based on that information.

E2 delivers ±1.5 cm horizontal and ±3 cm elevation accuracy under normal RTK operating conditions, with a bucket dynamic attitude accuracy of 0.2°. Actual results depend on correct reference-point setup, satellite visibility, and site conditions.

E2 is designed to work with a wide range of excavators, including swing-boom and offset-boom models, and mounts on most mainstream brands, including CAT, Komatsu, and Hyundai, in both large and compact size classes.

Installation and calibration take about 2 hours with a single operator using only common tools, with a single-button start for daily use. A new operator can typically learn to run the system efficiently in about 30 minutes.

E2 has built-in dual-SIM 4G and an adjustable-power UHF radio (0.5 W / 1 W / 2 W, 410–470 MHz), so it can receive RTK corrections via cellular network or a local base station without extra external modules. Bluetooth 4.2 and Wi-Fi are also built in for diagnostics and updates.

Yes. The hardware is IP67-rated and rated for operation from -30°C to +75°C, and storage from -40°C to +85°C, suitable for tunnels, wet sites, freezing mornings, and hot afternoons.

E2 supports multiple work modes for leveling, trenching, ditching, and slope work, including road construction, channel and drainage work, foundation excavation, and farmland leveling, so operators can switch between tasks on the same machine without additional hardware.

PRECISE field testing points to meaningful productivity gains compared to unguided digging, mainly from removing survey wait time and reducing rework. PRECISE does not publish a fixed percentage because actual results depend on site conditions and how the crew was working before adopting guidance.
