Sony CSL successfully sent signals to the

KSAT commercial optical ground station in Greece

Sony Computer Science Laboratories, Inc. (Sony CSL) and Kongsberg Satellite Services (KSAT) successfully demonstrated optical downlinks from a space terminal (Small Optical Link for ISS: SOLISS) on the International Space Station (ISS) to the KSAT commercial optical ground station in Greece. The communication format used is aligned with the CCSDS (141.0-B-1 + pink sheets for O3K) waveform standard.

This is a great step towards providing small and affordable laser communication terminals for both ground and space segments. Demonstrating such capabilities while in this campaign period is important to introduce these technologies to the market.

"This campaign was a great opportunity for KSAT to validate the performance of our first optical ground station and the start of the optical future" Hennes Henniger (Director Optical Solutions, KSAT) said.

The KSAT optical ground station in Greece is the first station of the Optical Nucleus Network. The Optical Nucleus Network is an informal collaboration between Space Agencies and industry which is going to make available an optical ground station network to serve optical terminals in space.

"Successful demonstration of optical downlinks from SOLISS to small and affordable optical ground station does not show fully operational readiness of the technology but it clearly shows commercialization on optical space to ground communication" Kyohei Iwamoto (Project Leader, Sony CSL) also said.

SOLISS is a small optical communication terminal currently attached to ISS for technology demonstration that is jointly developed by Sony CSL and Japan Aerospace Exploration Agency (JAXA).
