in a strategically placed network have successfully received laser signals from a German satellite, researchers say, paving the way to increase the capacity of space-to-Earth communications by a staggering 1,000 times.' initiative is led by astrophotonics scientist Sascha Schediwy from the University of Western Australia and funded by the Australian Space Agency's
"By switching to infrared laser beams for communications, we get a factor of 100, or 1,000, times greater bandwidth," said Schediwy. With such distinct advantages on offer, it could seem surprising that optical communications haven't been more widely adopted. But these laser-powered systems have a drawback.The team has a surprisingly simple solution. The system will have ground stations at several locations in WA connected to the same network, so hopefully, at least one station will always have a clear connection with the satellite.
If the Perth and Mingenew stations are both blocked by cloud, the TeraNet program has a final ace up its sleeve: an additional ground station receiver mounted on the back of a Jeep that can be driven out to whatever coordinates are necessary to achieve the best signal.on the east coast of Australia and in New Zealand to set up an Australasian optical ground station network, and that's only the beginning.
