ENPNewswire-August 8, 2019--JAXA and Sony CSL to Conduct In-Orbit Demonstrations of Long-Distance Laser Communication Using Japanese Experiment Module 'Kibo' on the International Space Station
The future EDRS-D payload will consist of three next-generation laser communication terminals (LCT) to allow simultaneous communication with several satellites, as well as aircraft and UAVs.
Also on display will be the firm's Modulating RetroReflector, capable of passively returning light from an interrogating laser source and modulating its intensity for free space laser communication. The current Modulating RetroReflector system has been demonstrated at a rate of 200kb/s in the near infrared wavelength range, with switching speeds as low as 3us.
