GS-260F UAV LiDAR System Application for Ultra-High Voltage Power Line Inspection

Project Background

Geosun GS-260F UAV LiDAR scanning system was deployed in a demonstration project for the State Grid Corporation of China, focusing on the inspection of a 1000 kV ultra-high voltage (UHV) power line.

Operation Parameters

• Flight Altitude: 120 meters AGL (20 meters above the 100 m-high towers)

• Flight Speed: 5 m/s

• Target Object: UHV transmission line corridor and tower structures

Equipment Highlights

The GS-260F integrates a 40-beam 905nm Class 1 laser unit with double echo return, achieving a data rate of 720,000 points/sec and a measuring range of 200 m @ 10% reflectivity. The system ensures high-density, full-coverage point clouds of both cables and tower tops at safe inspection altitudes.

• Horizontal Accuracy: ≤10 cm @ 150 m

• Position Accuracy: ≤5 cm

• Laser Field of View: 360° adjustable

• Pitch/Roll Accuracy: 0.005°, Heading Accuracy: 0.017°

• GNSS System: GPS, GLONASS, BDS, Galileo (Multi-band support)

Results & Feedback

• Accurate reconstruction of transmission lines and insulators, with clear cable sag and tower geometry.

• Seamless integration with gAirHawk point cloud processing software and Shuttle trajectory software for rapid data delivery.

• Operational safety ensured by maintaining UAV flight paths above dangerous structures while still capturing fine detail.

Client Testimonial

“The GS-260F provided reliable data even under high-voltage corridor interference. It’s a powerful solution for UHV grid asset inspection.”
