Excavator GNSS Machine Guidance
Wireless · 20-Minute Install
nonnav delivers centimeter-level excavator GNSS guidance for any machine. No surveyors. No complex wiring. Just turn it on and dig.
Works seamlessly with all major excavator brands
Engineered by nonnav (Wuhan)
The Brain Behind the Bucket
Advanced GNSS RTK fusion combined with dynamic IMU sensors, powered by our self-developed algorithm. Every component is engineered for one mission: turn any excavator into a precision-guided machine in under 20 minutes.
RTK Fusion
7 constellations, 30 frequencies, 1408 channels. Unshakable centimeter-level positioning even under tree canopy or near structures.
Dynamic Sensing
200Hz update rate with 60 degree tilt compensation. Precision remains perfect at any arm angle, cab orientation, or slope position.
Smart Algorithm
Proprietary sensor-fusion algorithm computes real-time depth, slope, and bucket trajectory with zero perceptible lag. No surveyor needed.
Beidou Native
Full BDS-3 native support with superior anti-jamming and signal-acquisition performance in challenging RF environments.

Frequently Asked Questions
Everything you need to know about implementing excavator machine guidance on your site.
How accurate is the nonnav guidance system? ▼
Dual Antenna system delivers ±3cm bucket tip accuracy. Single Antenna achieves ±1-3cm. Accuracy is maintained even during full cab rotation and on steep slopes thanks to 200Hz IMU sensor fusion.
How long does installation take? ▼
Completely wireless — no welding required. A skilled technician can complete installation in approximately 20 minutes. We provide 19 detailed tutorial videos covering every step.
Can I try the system before purchasing? ▼
Yes — we offer free trial units shipped to your site. No commitment required. Contact us to schedule a demo.
How does the price compare to Trimble or Topcon? ▼
Roughly 1/3 the price of foreign machine guidance systems, with comparable ±3cm accuracy and full Beidou-3 support. Most contractors achieve ROI within 2-3 months.
Which excavator brands does the system fit? ▼
Works with XCMG, Komatsu, Hitachi, Volvo, CAT and most hydraulic excavators. The wireless mounting kit adapts to different boom geometries without drilling or welding.
Does it work in rain, dust or extreme heat? ▼
Yes. The IMU sensors are IP67-rated against dust and water. The system operates from -20°C to 60°C and maintains accuracy in rain, snow and direct sunlight.
Is there any subscription or recurring software fee? ▼
No. You pay once for the hardware. Software updates are included free for the 2-year warranty period with no subscription required.
Can I move the system between different machines? ▼
Yes. The magnetic mounting kit makes relocation quick, so you can transfer the system from one excavator to another in about 30 minutes.
