Recently, zhao wu, chairman of feiyan aviation remote sensing technology co., ltd. and liu yanjing, general manager of Beijing fusde technology co., ltd. held a signing ceremony on the purchase of rieglvq-1560i airborne lidar measurement system, which once again laid the foundation for the hardware strength of feiyan in the industry.
Since the reform and opening up nearly 40 years ago, the country's infrastructure has undergone earth-shaking changes. Urban planning, transportation, water conservancy, agriculture, electric power and other basic industries require higher and higher production cycle and accuracy of planning and design drawings, which promotes the rapid development of China's geographic information industry.
As a new type of active aerial sensor, airborne lidar has the unique advantage that traditional means cannot replace in the rapid and accurate extraction of high precision 3d terrain data (digital elevation model (DEM)). In particular, for obtaining high-precision DEM data in some difficult mapping areas, such as vegetation coverage areas, coastal zones, reef areas and desert areas, the technical advantages of LiDAR are more obvious.
Following the development pulse of dixin-based industry, feiyan has invested tens of millions to introduce RIEGL vq-1560i airborne lidar measurement system, adhering to the principle of "high technology, high efficiency and high quality", and continuously providing high-quality modern surveying and mapping products and technical services for all industries.

Thanks to RIEGL's revolutionary MTA technology, the RIEGL vq-1560i is the only device in the world capable of truly achieving a laser emissivity of 2 million Hertz from 70 to 2,200 meters (relatively high altitude).
The adoption of RIEGL's self-developed and world-leading innovative technology, multi-beam transceiver capability (MTA), improves the point cloud density and measurement accuracy in the region with large topographic fluctuation, and greatly improves the working efficiency of the lidar system. The innovative technique breaks the previous limitation of having only one laser pulse in the air at any given moment, making it possible to have 10 or more laser pulses in the air at any given moment.
At a relative altitude of 2,000 meters or more, the number of laser pulses in the air at any given moment should not be less than 7 using MTA technology; Laser point cloud density per square meter of ground ≥6.
At the relative altitude of 3,000m or above, the number of pulses in the air at any instant shall not be less than 12 using MTA technology; Laser point cloud density per square meter of ground ≥4.
At a relative altitude of 4,000 meters or more, the number of laser pulses in the air at any given moment should not be less than 12 using MTA technology; Laser point cloud density per square meter of ground ≥2.
At a relative altitude of 5,000 meters or more, the number of laser pulses in the air at any given moment shall not be less than 12 using MTA technology; Laser point cloud density per square meter of ground ≥1.
