Among currently active inter-satellite communication systems, Starlink is by far the most numerous and with the highest bandwidth, reaching over 42 PB per day across its over 9000 space lasers ...

"SpaDeX Status Update: Arrested at Inter Satellite Distance (ISD) of 230 m, all sensors are being evaluated. Spacecraft's health is normal," ISRO said in a post on X.

“Arrested at Inter Satellite Distance (ISD) of 230 m, all sensors are being evaluated. Spacecraft's health is normal,” Isro ...

SpaceX’s Starlink network, which has more than 2 million subscribers and a big head start on Project Kuiper, is already taking advantage of optical inter-satellite links. “Starlink reports it ...

That technology is called “optical inter-satellite links” (OISL), a type of optical communication that uses infrared lasers to send data between spacecraft on orbit. OISL has been around for a ...

Isro’s SpaDeX mission aims to dock two satellites through precise maneuvers starting with a 20km separation, gradually reducing to enable inter-satellite communication. Successful docking will ...

The company isn’t unique in its interest in optical inter-satellite communications, with landmark and wide-scale development being prevalent in the 2010s. The European Space Agency demonstrated the ...

A long-distance laser communication link between two Earth-orbiting satellites has been established for the first time. The technique allows fast moving, low Earth orbit satellites to relay ...

In the past, long-distance free-space quantum communication experiments could only be implemented at night. During the daytime, the bright background sunlight prohibits quantum communication in ...

To estimate the range of inter-satellite communication in free space, the team applied a link budget analysis based on the Friis transmission equation, deriving an average theoretical distance of ...
