Geosun GS-120G

Key Features and Technology

• Integrated SLAM Technology: Features industry-grade SLAM algorithms, allowing for seamless and accurate positioning and mapping in areas where GNSS signals are poor or unavailable (e.g., indoors, tunnels, dense urban canyons).³ It supports both Pure SLAM and RTK-SLAM fusion.
• High-Density Data Capture: Equipped with a 32-channel rotating LiDAR sensor (often the Hesai XT32), the system captures up to 1,280,000 points per second (dual echo), ensuring a dense and reliable representation of the scanned environment.
• Wide Field of View (FOV): Offers an extensive scanning range with a 360° horizontal and 270° vertical field of view, minimizing blind spots and maximizing coverage with minimal effort.
• Real-Time Colored Point Cloud: The integrated high-definition RGB camera (typically 3 x 5 MP resolution) allows for the capture of real-time colored point cloud data, providing rich visual context for easier data interpretation and 3D modeling.
• High Accuracy: Achieves an Absolute Accuracy of  5cm and a Relative Accuracy of  1.5cm, ensuring survey-grade quality data.

Versatility and Design

• Multi-Platform Operation: The GS-120G features a minimalist and flexible design, allowing it to be mounted on multiple platforms, including:
  • Handheld (primary mode)
  • Backpack
  • Airborne (UAV/Drone payload)
  • Vehicle
• Robust Positioning System: Incorporates a high-performance Inertial Navigation System (INS) and multi-constellation GNSS module (GPS, GLONASS, BDS, GALILEO), ensuring centimetre-level accuracy when satellite signals are available.
• User-Friendly Workflow: Features a minimalist design, lightweight body (¹⁵$\approx 2.2\text{kg}$), and includes one-click data processing software (e.g., PointCreator) and an intuitive mobile App for real-time point cloud preview.
