Micro Satellite Laser Communications Project

The number of studies targeting microsatellites has been growing. Microsatellites typically weigh tens of kilograms, and the amount of resources that can be mounted on them is limited.

As laser transmission modules are reducible in size, they show great promise for microsatellite applications.

Without restrictions on frequencies or other restrictions on usage, lasers are free from international regulations and are considered a promising future means of communication.

NICT is working on the research and development of small optical transponders for micro satellites.
