GreenValley LiAir X4 Airborne Laser Scanning Unit

GreenValley LiAir X4: Precision LiDAR for Fully Autonomous Aerial Inspections

Designed for next-generation smart inspection missions, the GreenValley LiAir X4 combines lightweight design with powerful 3D data capture. This airborne LiDAR system integrates a 32-line rotary laser scanner, high-resolution camera, precision inertial navigation, and GreenValley's proprietary AirPilot autonomous flight system. It delivers accurate, real-time, full-coverage point cloud data from both air and handheld operations-even in GNSS-denied environments. With centimeter-level precision and rugged adaptability, the LiAir X4 is built to meet the real-world demands of professionals in utilities, mapping, forestry, and more.

Smarter Autonomous Flights, Safer Powerline Missions

The LiAir X4's AirPilot algorithm enables fully autonomous flight with real-time obstacle avoidance-even across complex powerline intersections and challenging terrain. Its rotary laser design delivers true 360° x 270° omnidirectional scanning with no data blind spots. Field operators can trust the LiAir X4 to identify trees, towers, and terrain changes mid-flight, maintaining safety and accuracy while reducing manual workload. Coupled with RGB tower photos and real-time DEM terrain following, it streamlines power infrastructure inspections like no other.

High-Resolution Data in Complex Environments

From forested slopes to crowded utility corridors, the LiAir X4 adapts to capture complete, georeferenced point clouds even in GPS-denied spaces using its SLAM-based handheld mode. It provides 26MP RGB imagery, true-color point cloud visualization, and centimeter-level accuracy across varied environments. Its robust internal storage and real-time video transmission empower users to make in-flight evaluations with confidence. Whether airborne or handheld, LiAir X4 delivers consistent data quality in every mission scenario.
