PARIS (CNES PR) — In partnership with CNES and Airbus Defense & Space and as part of the TELEO project, Safran Data Systems has successfully delivered the first in a series of digital modems dedicated to Earth-Space optical communications: the Cortex Lasercom.
Laser optical communications will make it possible to achieve speeds 10 to 100 times higher than the radio frequency communications currently used. Heir to the Cortex HDR, the world reference satellite imagery reception modem, Safran Data Systems has developed the Cortex Lasercom modem equipped with processing and decoding capabilities allowing to reach a record speed of 10 Gigabits per second of bit rate for Earth-Space optical communications, a level unequaled in the world.
The Cortex Lasercom will be used in several cooperation projects between Safran, Airbus and CNES, and will equip future optical ground stations (OGS) (Optical Ground Stations) marketed by Safran. These OGS will allow the link with all future satellites that will carry laser communication capabilities with the Earth. Two demonstrations on Airbus and CNES programs will take place in 2023, a world first: LASIN on the constellation of CO3D imaging satellites, and TELEO on the future BADR-8 telecommunications satellite. On this occasion, the Cortex Lasercom will be equipped with error-correcting codes developed by Airbus Defense & Space, which make it possible to deliver useful and error-free information to the user.
