—— Smart Guidance Algorithm Real-time depth, slope, and bucket trajectory calculation

GNSS RTK Fusion

Ultra-compact receiver supporting GPS, BDS, GLONASS, Galileo, QZSS, IRNSS, and L-Band — 7 constellations, 30 frequencies for robust positioning in any environment.

Dynamic IMU

200Hz high-update-rate inertial measurement unit with 60° tilt compensation. Deep fusion of satellite positioning and inertial navigation ensures accurate bucket tip positioning at any arm angle.

Smart Guidance Algorithm

Self-developed algorithms calculate real-time depth, slope, and bucket trajectory. Graphical and numerical guidance means operators see exactly how deep and level they are — instantly.

Beidou Native

Full Beidou-3 support with dual-frequency signals. Built-in anti-jamming technology and ionospheric suppression algorithm maintain fixed-solution stability even under challenging conditions.

Product Features

Refined through one year of co-development with over 100 frontline excavator operators.

±3cm

Centimeter Precision

Real-time bucket tip positioning within ±3cm, enabling consistent accuracy for leveling, sloping, and trenching operations.

20min

Quick Installation

Fully wireless design — no welding required. A skilled technician can complete installation in approximately 20 minutes.

Real-Time Feedback

Operators see depth, slope, and bucket position on-screen instantly. One glance tells you how deep and how level — no second-guessing.

Reduced Skill Dependency

Novice operators can achieve experienced-level precision with real-time guidance. No dedicated surveyor required on site.

Application Scenarios

Four core excavator operations, each powered by intelligent GNSS guidance.

L

Leveling

Excavator leveling guidance

Automatically guides the bucket based on GNSS elevation data to achieve ±1-3cm flatness. Eliminates manual grade checking and repeated measuring.

S

Sloping

Excavator sloping guidance

Calculates bucket trajectory based on the design slope angle. Forms precise ramps and cross-sections without manual stakeout.

T

Trenching

Excavator trenching guidance

Pre-set trench parameters then auto-generate the optimal excavation path. Supports V-shaped and rectangular cross-sections.

C

Parameter Check

Sensor parameter check interface

Rapidly verify all key sensor and receiver parameters to confirm the system is operating within specification before starting work.

Frequently Asked Questions

How accurate is the Nonnav guidance system?
The dual-antenna version achieves ±3cm bucket tip accuracy. The single-antenna version delivers ±1-3cm digging precision. Both leverage GNSS RTK fusion with dynamic IMU for consistent, repeatable results.
How long does installation take?
Approximately 20 minutes for an experienced technician. All connections are wireless — no welding, no cable routing required. The system is ready to work immediately after mounting and calibration.
Does the system require a surveyor on site?
No. The GNSS-based guidance eliminates the need for dedicated surveyors. Operators see real-time depth and slope data on the display, enabling them to work independently with centimeter precision.
What satellite systems are supported?
Full support for GPS, Beidou (B1/B2/B3), GLONASS, Galileo, QZSS, IRNSS, and L-Band — 7 constellations across 30 frequencies. Maximum satellite availability in any environment.
What warranty and support do you offer?
Every system comes with a 2-year host warranty, 1-on-1 training, 24-hour online support, and free trial available. We provide full lifecycle support for all our products.
