GreenValley LiAir X3-H Airborne Laser Scanning Unit

GreenValley LiAir X3-H Airborne Laser Scanning Unit: 720,000 pts/s Triple-Return LiDAR with 5 cm Accuracy and Hybrid SLAM Mapping

The GreenValley LiAir X3-H Airborne Laser Scanning Unit is a lightweight UAV LiDAR system designed for high-efficiency mapping, inspection, and surveying workflows. It integrates a 905 nm LiDAR sensor, 200 Hz IMU, multi-constellation GNSS, and a 26 MP APS-C mapping camera into a compact 1.25 kg (2.76 lbs) payload. This allows synchronized capture of point cloud, positioning, and imagery data in a single flight.

The system also supports hybrid operation through an optional handheld SLAM module, enabling data collection in both GNSS-available and GNSS-denied environments. With scan rates up to 720,000 points per second and detection ranges up to 450 m (1,476 ft), it is designed for flexible deployment across varied terrain and structures.

Key Features and Benefits

• High-speed LiDAR scanning: Up to 720,000 points per second capture rate.
• Triple-return capability: Captures multiple surfaces for vegetation and terrain modeling.
• Lightweight payload design: 1.25 kg supports extended UAV flight durations.
• Detection range performance: Up to 450 meters at high reflectivity surfaces.
• Survey-grade accuracy: 5 cm vertical accuracy at 70 meters altitude.
• Integrated mapping camera: 26 MP APS-C sensor captures detailed imagery.
• Multi-GNSS positioning: GPS, GLONASS, BeiDou support improves georeferencing accuracy.
• Hybrid SLAM capability: Enables mapping in GNSS-denied indoor environments.
• Efficient coverage rate: Up to 100,000 square meters per hour mapping.

Flexible UAV and SLAM Mapping for Multi-Environment Data Collection

The LiAir X3-H is designed to support both aerial and ground-based data acquisition workflows. In UAV mode, it captures LiDAR and imagery data across large areas at typical flight speeds of 5–10 m/s (11.2–22.4 mph), maintaining consistent coverage and point density. The triple-return LiDAR improves terrain modeling by capturing multiple reflections per pulse.

In handheld mode, the system uses SLAM and PPK-SLAM to generate accurate point clouds in environments without GNSS signals. This enables indoor scanning, building interiors, and complex structures while maintaining centimeter-level fusion accuracy when combined with aerial datasets.
