Project young specialists of RSC Energia, entitled “Secure optical communication system with passive transmitter”, or more simply — laser communication system – won the day in the competition for grants of the Moscow region Government in the fields of science, technology, engineering and innovation in 2016.
Until recently the crews of space ships that were landing, it was not possible to communicate with the Ground during the passage of the dense layers of the atmosphere plasmaoptical. And all because of the fact that the plasma is impervious to radio waves.
In addition, a laser system transmitting and receiving information enable you to transfer data at speeds of tens to hundreds of times greater than that which can provide modern radio systems. Besides the laser signal can be sent to tens of thousands of kilometres with a very high degree of protection from outside interference.
Have the laser system and the cons. For example, the signal can be interrupted by thick clouds or fog. However, the location of the landing places of the spacecraft is such that they more characteristically cloudless sky.Related posts:
