Between the ISS and Earth held a session of laser communication
On the orbital station ISS with the goal of improving the quality of communication was installed module OPALS (Optical Payload for Lasercomm Science), this equipment has improved the quality of communication significantly. Experiments conducted by scientists from NASA, all the equipment worked normally. If such equipment to learn at all stages of communication with the orbital station, then it is almost comparable to a communication breakthrough. To control many systems at considerable distances has now become much simpler. While this is only a test section connection and was only able to communicate between the station in the Laboratory of the study of jet propulsion (JPL) and the ISS. We also communicate with another station on the island of Tenerife. When the station was flying over Europe, contacted by the laser channel with the German aerospace center in Oberpfaffenhofen. At night loss of signal on the laser channel at times less than, the connection quality is much better. In the daytime the signal quality is worse though, but through the use of modern equipment and in the daytime were able to achieve speeds comparable to the channels by which every 3.5 seconds to send a package weighing 175 megabits. If you take the usual channel of communication with the ISS, it is possible to pass such a package, it will take at least 10 minutes. In new conditions it is possible to transmit the same packet of information already in only 148 seconds. Over time, the transfer rate will only grow and already there are reports that the tests were able to raise the speed to a level of 200 to 300 megabytes. In General transmission was spending three hours earlier, now everything is conveyed in just 20 seconds.
