Laser, meet Layover
World-first gigabit laser link between aircraft and geostationary satellite
Netflix from the sky, but is the lag a deal‑breaker
TLDR: ESA and Airbus hit 2.6 Gbps linking a plane to a geostationary satellite, promising faster in‑flight internet. Commenters cheered the speed but argued over ~0.5‑second lag and scaling, asking if ‘low‑latency’ means low‑orbit satellites or smarter tracking.
Europe just shot a laser internet beam from a plane to a satellite parked 36,000 km up—clocking 2.6 gigabits per second and an error‑free connection for minutes. Translation: HD movies in seconds and potentially reliable Wi‑Fi while flying. ESA and Airbus are hyped, calling it secure and “low‑latency.” The crowd? Equal parts amazed and side‑eye.
The hottest clash: speed vs. lag. One camp cheered the sci‑fi moment; another roasted the round‑trip delay, with xnx estimating ~0.5 seconds and Meneth asking whether “low‑latency” means “actually low” or “we meant Low Earth Orbit.” Scaling drama popped off too: cm2187’s “doesn’t scale” take sparked visions of air traffic control playing laser tag with every plane. Meanwhile, nerd thirst hit hard—myrmidon demanded details on tracking, beam spread (“cat laser dot at 36,000 km?”), power and wavelength. Utopiah arrived with receipts, dropping more info from TNO here and the ESA project page here.
Bottom line: commenters love the speed and security promise (narrow beams, fewer eavesdroppers), but they’re sparring over whether half‑second ping makes this space Wi‑Fi feel more like space snail. The meme energy? “Beam me Netflix, but maybe buffer me patience.”
Key Points
- •ESA, Airbus Defence and Space, TNO and TESAT demonstrated a laser link between an aircraft and the geostationary satellite Alphasat TDP‑1.
- •Airbus’ UltraAir terminal sustained an error‑free 2.6 Gbps connection for several minutes during test flights over Nîmes, France.
- •Laser communications were highlighted as more secure and higher‑capacity than radio due to narrower beam spread.
- •The system maintained precise connectivity despite aircraft motion, vibrations, clouds and atmospheric variations over a 36,000 km path.
- •UltraAir was developed under ESA’s ScyLight programme within ARTES, with support from NSO and DLR; ESA’s HydRON and HAPS links are strategic priorities.
