Second-Generation Lidar from NRG Systems and Leosphere


NRG Systems, manufacturer of wind measurement equipment, and Leosphere, a specialist in lidar for atmospheric observations, announces the introduction of the WINDCUBE® v2, the lightest, most compact lidar remote sensor available. Used in site assessment and wind farm performance monitoring, it collects actual measurements at heights up to 200 meters, mapping the vertical wind component, wind speed, and direction, turbulence, and wind shear.

“Lidar has quickly become the must-have tool in resource assessment,” says Alex Sauvage, president and CEO of Leosphere. “Over the past year our two companies have worked tirelessly to enhance the portability and durability of our lidar remote sensor, making it ideal for complex terrain, remote locations, and offshore.”

Weighing 45 kg and measuring approximately 55 cm square, the WINDCUBE v2 features no internal moving parts, multiple communications options (including satellite), low power requirements (45 watts), and an all-weather enclosure. The quiet, ultra portable 200m wind profiler includes 10 programmable measurement heights, providing ready to use data.

“By collecting actual measurements of the entire swept area of the wind turbine, the WINDCUBE v2 improves data accuracy and reduces overall uncertainty of the wind farm design,” says John Norton, COO for NRG Systems. “Improved certainty can make the difference between project success or failure.”

The WINDCUBE v2 is an active remote sensor that operates by emitting a laser pulse through the atmosphere. Along its path the laser light is backscattered by aerosols in the air and received by an optical sensor in the lidar unit. These signals capture the shift in atmospheric particles, or the absolute wind speed in the lidar line of sight. For more information visit Also go to or
