Optical Inter-Satellite Links (Starlink)

“SpaceX proposed reliance on optical inter-satellite links for communications between satellites and with Starlink spacecraft that would relay data to Earth.”

“SpaceX began adding optical inter-satellite links to its Starlink low Earth orbit broadband constellation in early 2021 to avoid the need for ground stations over the poles to achieve global coverage.”

“SpaceLink is building a constellation of relay satellites in medium Earth orbit that use optical inter-satellite links to speed communications between spacecraft in orbit and users on the ground.”
