2‑Watt Laser Satellite Communication: A Quiet Revolution in Space Connectivity
In an era dominated by radio‑frequency (RF) satellite communication, a modest 2‑watt laser perched on a satellite 36,000 kilometres above Earth has achieved something remarkable: transmitting data at 1 gigabit per second (Gbps). Using roughly the power of a nightlight, this laser beam has successfully bridged the vast distance of geostationary orbit, piercing through Earth’s turbulent…
