GEOSUN GS-200G Mobile LiDAR System

The GEOSUN GS-200G Mobile LiDAR System is a lightweight handheld SLAM-based 3D laser scanning solution designed for high-precision mobile mapping in indoor and outdoor environments. Integrating advanced LiDAR technology, GNSS positioning, IMU sensors, panoramic imaging, and real-time SLAM algorithms, the GS-200G enables rapid point cloud generation for surveying, construction, BIM, mining, infrastructure inspection, forestry, and digital twin applications.

Built for portability and operational efficiency, the GS-200G delivers professional-grade 3D spatial data acquisition while minimizing field setup time and simplifying mapping workflows. Its compact architecture allows operators to scan complex environments quickly without relying on conventional static terrestrial scanning methods.

The system is optimized for professionals requiring accurate geospatial data collection in both GNSS-available and GNSS-denied environments.

Introduction to the GEOSUN GS-200G

Modern geospatial projects demand faster surveying solutions with higher operational flexibility. Traditional tripod laser scanners often require multiple setups, complex registration procedures, and extensive field labor. The GEOSUN GS-200G addresses these challenges through integrated SLAM (Simultaneous Localization and Mapping) technology.

The scanner continuously captures laser measurements while the operator walks through the environment. Real-time trajectory calculation and positioning algorithms allow the system to generate dense 3D point clouds efficiently.

The GS-200G combines:

• Livox Mid-360 LiDAR sensor
• GNSS positioning system
• High-precision IMU
• Panoramic imaging cameras
• SLAM processing engine
• Mobile mapping software

This integration creates a portable all-in-one LiDAR solution for fast field deployment.
