GreenValley LiAir X3-H Airborne Laser Scanning Unit: 720,000 pts/s LiDAR with Triple Returns and Hybrid UAV–SLAM Mapping

The GreenValley LiAir X3-H Airborne Laser Scanning Unit is a compact LiDAR payload designed for flexible mapping across aerial and ground-based workflows. It integrates a 905 nm LiDAR sensor, 200 Hz IMU, multi-constellation GNSS, and a 26 MP APS-C camera into a 1.25 kg (2.76 lbs) system, enabling synchronized capture of point cloud, positioning, and imagery data.

The system supports both UAV deployment and optional handheld SLAM operation, allowing data collection in open environments and GNSS-denied areas. With scan rates up to 720,000 points per second and detection ranges up to 450 m (1,476 ft), it provides consistent data capture across varied project conditions.

Key Features and Benefits

• High-speed LiDAR acquisition: Up to 720,000 points per second scanning rate.
• Triple-return functionality: Captures multiple surfaces for improved terrain reconstruction accuracy.
• Compact system weight: 1.25 kg enables efficient UAV deployment and handling.
• Detection range capability: Up to 450 meters at high reflectivity targets.
• Mapping accuracy: 5 cm vertical accuracy at 70 meters altitude.
• Integrated imaging system: 26 MP APS-C camera captures mapping-grade imagery.
• Multi-GNSS positioning: GPS, GLONASS, BeiDou improve geospatial alignment accuracy.
• Hybrid operation mode: Supports UAV mapping and handheld SLAM data collection.
• High coverage efficiency: Up to 100,000 square meters per hour mapping.

Flexible Data Capture Across Aerial and Ground Environments

The LiAir X3-H operates across multiple data collection modes depending on project requirements. In UAV deployments, it captures LiDAR and imagery data at flight speeds of 5–10 m/s (11.2–22.4 mph), maintaining consistent point density across survey areas. Triple-return LiDAR improves surface modeling by capturing multiple reflections per pulse.

When used with the handheld module, the system applies SLAM and PPK-SLAM workflows to collect data in environments without GNSS signals. This enables indoor mapping, confined spaces, and structural scanning while maintaining alignment with aerial datasets for unified point cloud outputs.
