Committee on Radio Astronomy Frequencies

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

Definition:

Space Operation Service: A radiocommunication service concerned with the operation of spacecraft, in particular space tracking, space telemetry and space telecommand. These functions will normally be provided within the service in which the space station is operating.

• ITU-R Radio Regulations allocations for Region 1
• Potential pressure to the Radio Astronomy Service
