Specifically, in a deal between Alphabet and the Sri Lankan government, the two entities will be exchanging access to
needed radio frequency spectrum on which the balloons will be transmitting data for a stake in the project.
The mission of CRAF is to keep the
frequency bands used for
radio astronomical observations free from interference, to argue the scientific
needs of the European research community for continued access to and availability of the
radio spectrum for
radio astronomy, and to support related science communities in their
needs concerning interference - free
radio frequency bands for passive use.
