Committee on Radio Astronomy Frequencies

The Committee on Radio Astronomy Frequencies (CRAF) is a committee of the European Science Foundation (ESF).

Definition:

Radionavigation-Satellite Service: A radiocommunication service used for the purpose of radionavigation. This service may also include feeder links necessary for its operations.
