France tests space lasers for secure satellite downlink in world first

Good news!

"French technology firms used laser to communicate between a low-orbit nano satellite and a commercial ground station in an experiment sponsored by the French Defence Innovation Agency, with France’s Armed Forces Ministry dubbing the test a world first. ...

The point-to-point nature of lasers makes them more secure than radio frequencies, and they can’t be jammed the way radio can ... Additionally, a laser link can transfer very large files such as detailed Earth images in minutes, something that might require multiple orbits using radio signals ..."

"... they succeeded in establishing a stable laser link over several minutes, demonstrating the tracking of the nano-satellite in low orbit by the optical ground station and the establishment of a closed-loop laser link. ..."
