Overview
The PolyNav 4000A GNSS/INS LiDAR RTK Survey System is a high-precision multi-sensor positioning solution designed for advanced surveying, mapping, and mobile data collection applications. By integrating GNSS, INS (IMU), LiDAR, and camera technology into a single platform, it delivers centimeter-level positioning accuracy and reliable performance in both open and GNSS-denied environments.
Engineered for demanding field conditions, the system combines real-time RTK positioning with inertial navigation to maintain accuracy even in tunnels, urban canyons, and obstructed areas. The integrated LiDAR sensor enables high-resolution 3D data capture, while the onboard camera enhances mapping and visualization workflows.
With fast data acquisition, stable signal tracking, and efficient processing capabilities, the PolyNav 4000A provides a complete, field-ready solution for professionals requiring precise and reliable spatial data.
How EMC Shop Customers Use This Product
The EMC Shop customers use the PolyNav 4000A as a mobile LiDAR mapping and RTK positioning system for capturing high-accuracy spatial data in challenging environments. The system is typically mounted on vehicles, backpacks, or mobile platforms to perform continuous data collection while in motion.
In practice, this system is widely used for:
- Mobile mapping and corridor surveys
- Topographic mapping and terrain modeling
- Infrastructure inspection and asset mapping
- 3D modeling and digital twin creation
The GNSS/INS integration ensures continuous positioning even when satellite signals are weak or unavailable, while the LiDAR sensor captures dense point cloud data in real time. Operators can efficiently process and analyze collected data for mapping, surveying, and engineering applications.
This workflow enables faster data collection, reduces field time, and improves accuracy in complex environments where traditional surveying methods are limited.
