The Stream LinePro unit is an autonomous, turn-key LiDAR system incorporating an internal scanner housed in an environmental enclosure.

The internal scanner gives a reduced field of regard of 70 to 90 in elevation at any azimuth. The flexible data acquisition software allows VAD scans, DBS wind profiles, staring and arbitrary scans to be scheduled. The further wind profiling software allows 4 to 360 point VAD + vertical scans, with an update every 2 seconds at all heights - which could be up to 3200 heights.

The screenshot (right) shows the wind profiling software displaying a very high resolution wind profile consisting of 380 separate heights - 1km. This display is updated every 2 seconds. A 16-point VAD scan + vertical ray was performed.

Our Wind profiling Stream Line systems and the wind power targeted Galion systems have always included a vertical ray by default in the VAD scan arrangement.

 

The screen shot above shows the display from the scan scheduled software. The system has been scheduled to stare vertically for the majority of the time, and performs a VAD scan and a DBS type wind profile every few minutes.

The software allows UDP data broadcast, and logging to the embedded controller, or to an attached or LAN connected drive. A GPS module can be added to provide position information and for use with time synchronisation.

There is also the option to add a met mast, which will monitor the local temperature, pressure and humidity.
