Communications satellite

A communications satellite is an artificial satellite that relays and amplifies through the use of a transponder, radio telecommunications signals, between a source and a receiver.

Fixed-satellite service

Fixed-satellite service (short: FSS) is – in line to ITU Radio Regulations – a radio-communication service between earth stations at given positions, when one or more satellites are used; the given position may be a specified fixed point or any fixed point within specified areas; in some cases this service includes satellite-to-satellite links, which may also be operated in the inter-satellite service; the fixed-satellite service may also include feeder links for other space radiocommunication services.

Frequency allocation

Use of radio frequency bands of the electromagnetic spectrum is regulated by governments in most countries, in a Spectrum management process known as frequency allocation or spectrum allocation.

Rain fade

Rain fade refers primarily to the absorption of a microwave radio frequency (RF) signal by atmospheric rain, snow or ice, and losses which are especially prevalent at frequencies above 11 GHz.
