GS-200G

Key Features:

• Integrated Design: The GS-200G combines a Livox Mid-360 laser scanner with a GNSS (Global Navigation Satellite System) and IMU (Inertial Measurement Unit) positioning and attitude determination system (gSpin 210). This integration allows for seamless data collection even in GNSS-denied areas.
• High Accuracy: It boasts impressive accuracy, with relative accuracy of $\le 1\text{ cm}$ and absolute accuracy of $\le 5\text{ cm}$. The laser unit itself offers a range accuracy of $\le 2\text{ cm}$ at $10\text{ m}$ and $\le 3\text{ cm}$ at $0.2\text{ m}$.
• Efficient Data Capture: The Livox Mid-360 sensor enables non-repetitive scanning, providing up to $200,000\text{ points/second}$ (single echo) to create dense 3D point clouds. It has a measuring range of $40\text{ m}$ at $10\%$ reflectivity and $70\text{ m}$ at $80\%$ reflectivity.
• Wide Field of View: The laser unit offers a 360∘ horizontal FOV and a vertical FOV of −7∘ to 52∘, ensuring comprehensive data capture.
• Built-in Camera: Equipped with two $20\text{ MP}$ cameras, the system can capture time-synchronized images, allowing for colorized point clouds and richer visual data.
• Multi-Platform Compatibility: While primarily a handheld system, the GS-200G can also be mounted on backpacks or used with other DIY options, offering flexibility in deployment.
• Advanced Software: The system includes post-processing software that outputs point cloud data in standard formats like LAS and custom TXT, facilitating further analysis and modeling.
• Robust POS Unit: The gSpin 210 POS unit provides high-precision positioning and orientation data, with an update frequency of $200\text{ Hz}$, pitch and roll accuracy of 0.015∘, and heading accuracy of 0.040∘. It supports multiple GNSS signals including GPS, GLONASS, BDS, and GALILEO.
• Compact and Portable: Weighing approximately $1.0\text{ kg}$ and with dimensions of $16.5\times 12.0\times 32.4\text{ cm}$, the GS-200G is designed for easy mobility and extended use in the field.
• Applications: Ideal for urban surveys, infrastructure inspection, digital twin modeling, indoor and outdoor mapping, and various other applications requiring high-precision 3D data.
