E2 in the Field

PRECISE E2 is a 3D excavator guidance system that senses the bucket's real-time position against the target grade and displays the deviation in-cab, so one 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. Checking depth or slope means stopping the machine and calling in a surveyor or stake crew, then repeating until it's right, which means idle machine time and a real risk of over- or under-digging when no one is available to check.

Solution

E2 combines dual GNSS positioning with dual IMU attitude sensing to calculate the bucket edge's real-time 3D position, then displays the live gap to the target elevation or slope on the in-cab touchscreen as the arm, boom, and bucket move.

Value

The operator sees the number on screen instead of waiting for someone else to measure, so there are fewer stoppages, less rework, and more consistent results across operators.

Key Benefits

Why E2

Dual GNSS-IMU Bucket Sensing

Real-Time Bucket Position and Grade Deviation

The operator always knows how much material is left to remove without stopping to call for a check.

Dual GNSS positioning and dual IMU sensing calculate the bucket edge's 3D position, showing the live deviation from the target depth, slope, or trench line.

Multi-View On-Screen Guidance

Multi-View Construction Guidance

Operators judge the target relationship faster and more intuitively, especially on slopes and trenches.

One-Operator In-Cab Guidance

One-Man Excavation, No Layout Crew

Frees up survey labor and removes the wait between "dig a bit" and "check the result."

Operator-Set RTK Reference Point

Reference-Based, Repeatable Operation

Every cut after that is measured against the same baseline, so results repeat across shifts and operators.

Applications

Where It's Used

Trenching: track trench depth and alignment continuously without repeated stake checks.
Slope trimming: hold a consistent slope angle across long runs of cut or fill.
Channel clearing and fine grading: finish to design elevation without over-cutting and re-filling.
Basement and foundation excavation: manage staged, layered digging with a consistent reference.

What Our Customers Are Saying

Luis

Mexico

We no longer need a survey crew on-site. Just me and the machine — that's it.

Andi

Indonesia

Once we set the reference point, everything else just flowed. Accurate and repeatable.

Azman

Malaysia

The setup was done in under 10 minutes. My team was shocked how easy it was.

Marcelo

Brazil

We installed it on four different excavators — all from different brands. No issues.

Technical Highlights

Engineered Detail

Dual GNSS + Dual IMU for continuous bucket-position tracking through boom, arm, and bucket rotation.

All-constellation, multi-frequency GNSS tracking (BDS, GPS, GLONASS, Galileo, QZSS, SBAS) for stable fixes even in partially obstructed sites.

Built-in 4G dual-SIM and UHF radio (0.5W/1W/2W adjustable) so the system stays connected whether working with cellular correction services or a local base station.

IP67-rated hardware rated from -30°C to +75°C operating temperature for use across tunnels, wet sites, freezing mornings, and hot afternoons.

10.1" glove-friendly, sunlight-readable touchscreen for clear guidance display in direct sun or at night.

Modular, compact hardware designed for minimal cab intrusion and fast field installation or replacement.

Multi-mode support for trenching, slope work, and grading from the same unit.

Compatible with major excavator brands including CAT, Komatsu, and Hyundai, on both large and compact machines.

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.

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 mount on most mainstream excavators, including CAT, Komatsu, and Hyundai models, in both large and compact size classes.

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 uses modular hardware and a guided calibration process designed to get the system operational without specialized equipment. Typical setup time is under 10 minutes for a crew already familiar with the process, based on PRECISE installation testing; actual time depends on the machine and installation conditions.

E2 supports multiple work modes for trenching, slope trimming, channel clearing, and fine grading, so operators can switch between tasks on the same machine without additional hardware.
