Satellite data transmission using laser light
For the first time, a data link between satellites was established using a laser beam as signal carrier.
On board the European Space Agency's Artemis satellite is the SILEX system. This system provides an optical data transmission link with an Earth observation satellite SPOT 4, which is orbiting the earth.
Through the laser data link, images taken by SPOT 4 can be transmitted in real time to the image processing centre in Toulouse, France, drastically reducing the time between taking the picture and its delivery to the centre.
This is possible whenever the two satellites are in line of sight. Without this, the images are stored on board in SPOT 4's memory and dumped to the ground stations.
During the period when the two satellites were communicating, test data was transmitted at a rate of 50 Mbps, and the data stream was confirmed as being highly accurate.
