One of the most important parameters to consider in observatories having large telescope is the control and minimization of vibrations reached the main mirror of the telescope caused by the wind flow.
The confined wind flow in the dome creates small or large vortexes which lead to increase or decrease the local pressure around the telescope, which causes vibrations in the mirror of the telescope. These vibrations disturb the Imaging operation of the telescope.
In large observatories, the windscreen cannot overcome this problem individually. An effective solution to this problem is to establish special flow control windows to the walls of the dome. These windows are controlled by a sophisticated software system. The system constantly receives the velocity and the direction of the wind from the weather station, puts a number of windows in the open or closed position, and avoids turbulence to a large extent in the dome.
For the first time in the country, IPTEC group has indigenized the software and hardware needed for this system and is ready to provide this service for the customers.
