The Ahmedabad unit of Space Applications Centre (SAC) of the Indian Space Research Organization (ISRO) has signeds a three-year Memorandum of Understanding (MoU) with city-based Nav Wireless Technologies Pvt Ltd (NavTech) to use light-based high-speed communication for satellite communication in space, an official release stated.
Making the shift to optical wireless technologies from radio frequency in satellite communications, SAC will use “high-speed, secure quantum key communication using light from base station to satellite in space and terrestrial communication.”
According to the release, through this LiFi technology, SAC will be able to do the quantum key distribution and pointing acquisition and tracking for satellite-to-satellite communications in the space. This communication technology is “all set to be used in ISRO’s upcoming space exploration programmes”, it added.
