China beats Starlink to hi-res space-ground laser transmission at 6G standard

Commercial satellite company sets 100Gbps speed record – 10 times faster than its previous feat less than a year earlier. — SCMP

China has achieved a breakthrough in satellite-to-ground laser communications that could pave the way for 6G and other applications including remote sensing with ultra-high resolution and next generation satellite positioning technology.

Chang Guang Satellite Technology Co, which owns Jilin-1, the world’s largest sub-metre commercial remote sensing satellite constellation, said it achieved a 100 gigabit per second ultra-high-speed image data transmission rate in testing last weekend.
