Sony CSL and JAXA Successfully Demonstrate Complete Data File Transfer in Error

2022/1/27

Sony CSL and the Japan Aerospace Exploration Agency (JAXA, President: Hiroshi Yamakawa), as part of JAXA's Space Innovation through Partnership and Co-creation (J-SPARC) program, have successfully conducted an experiment to transfer a complete data file in a simulated low-quality and error-prone communications environment. Accomplishing transfer data in a strict environment is key to future stratospheric and low-Earth orbit optical communications, and Sony CSL and JAXA have established the technical foundations for the commercialization of this technology.

With this successful demonstration, a solution is in sight to the high speed, high bandwidth, and low energy consumption requirements of point-to-point optical internet service in the stratosphere or low-Earth orbit. We expect this to lead to future business development opportunities for communication services, such as small optical communication terminals installed on low-Earth orbit satellite constellations, or unmanned aircraft for stratospheric telecommunications.
