The National Institute of Information and Communications Technology (NICT), collaborating with the Nagoya Institute of Technology and Japan Aerospace Exploration Agency, has achieved a world-first demonstration using advanced error correction codes to mitigate atmospheric turbulence in ground-to-satellite laser communications.

Atmospheric turbulence during ground-to-satellite laser links results in fading, causing burst data errors. Leveraging next-generation error correction codes such as 5G NR LDPC and DVB-S2, the team transmitted data and successfully corrected these burst errors, leading to a marked improvement in communication quality compared to conventional methods.

For this project, NICT used its 1-meter optical ground station and JAXA's Laser Utilizing Communication System on a
