The RIEGL VQ-1560i Airborne LiDAR, owned and operated by Feiyan Remote Sensing, is an ultra-high-performance professional surveying device integrated with dual-wavelength waveform processing technology. Specifically designed for ultra-large-area mapping and high-density point cloud acquisition scenarios, it features two laser channels supporting simultaneous green laser and near-infrared (NIR) measurement. With an ultra-high laser pulse repetition rate and multi-cycle echo processing capability, it enables rapid wide-area coverage during medium-to-high altitude operations while delivering high-fidelity, high-density point cloud data. Its unique forward/nadir/backward scanning function and wide field of view design can accurately capture complex terrain and ground object details. Combined with flexible integration features and industrial-grade stable quality, it serves as a core equipment for Feiyan Remote Sensing to provide high-quality services in large-scale national land surveying, smart city construction, ecological environment monitoring and other fields.

Technical Specifications

Core Advantages

Dual-Wavelength High-Efficiency Acquisition：Dual laser channels support simultaneous green laser and NIR measurement, with 1 MHz per channel laser pulse repetition rate and 1.33 million measurements per second. Combined with a maximum operational efficiency of 857 km²/h, it significantly shortens the cycle of ultra-large-area projects and improves Feiyan Remote Sensing's service delivery capability.

Superior Data Fidelity & Completeness：Advanced full waveform processing technology and MTA multi-cycle echo processing (supporting up to 25 simultaneous pulses in the air) can penetrate dense vegetation and building occlusions. Dual-wavelength data complementarily enhances target features, providing high-precision and high-integrity data support for Feiyan Remote Sensing's surveying services.

Flexible Full-Scenario Adaptability：58° wide FOV combined with forward/nadir/backward scanning function adapts to medium-to-high altitude operation needs. Point density can be flexibly adjusted from 0.5 to 60.2 pts/m², meeting both wide-area national land surveying and high-density urban 3D modeling requirements, covering multiple industry service scenarios of Feiyan Remote Sensing.

Industrial-Grade Stable Operation：IP54 protection rating and operating temperature range of -25℃~+60℃ can withstand extreme climates and complex outdoor environments. The integrated ruggedized design enhances vibration and interference resistance, ensuring the stability and continuity of Feiyan Remote Sensing's long-term operations.

Seamless Integration & Smart Processing：Seamlessly integrates high-performance IMU/GNSS system and high-pixel camera, supporting synchronous multi-modal data acquisition. Real-time waveform processing and intelligent analysis technology shorten data processing cycles, optimizing the overall efficiency of Feiyan Remote Sensing's services.

High-Density Uniform Point Cloud：The optimized scanning system design ensures uniform point cloud distribution across the entire field of view, with a point density of over 50 pts/m². It provides a high-quality data foundation for high-precision 3D modeling and digital twin construction, facilitating the implementation of accurate applications in various professional scenarios.
