fixed satellite service (satellite comm.) (FSS)

Fixed Satellite Service (FSS) is the term used in the U.S. and Canada to describe a satellite service provided by a GEO satellite. Fixed Satellite refers to geostationary satellites. In Europe, Fixed Satellite Service is interpreted as satellite service between fixed terrestrial stations on the Earth's surface.

GEO satellites are about transmitting their telecommunications and broadcast services from a fixed orbital position. In this process, the signals are transmitted via the uplink from a stationary or mobile ground station to the satellite, converted there in terms of frequency and transmitted to the earth in the downlink. In addition to pure transmission and distribution services, FSS services can also be used to operate all interactive services with a return channel.

There are several frequency bands made available for Fixed Satellite Services. These include the frequency band between 3.7 GHz and 4.2 GHz in the C band and the frequency bands used in Europe for the downlink between 10.7 GHz and 11.7 GHz and between 12.5 GHz and 12.75 GHz in the Ku band. In addition, the Federal Communication Commission( FCC) has allocated an 8 GHz frequency band in the Q/ V band between 36 GHz and 56 GHz, and the International Telecommunication Union( ITU) has allocated the Ka band between 29.5 GHz and 30.0 GHz for FSS applications worldwide.

The Federal Communications Commission (FCC) has made initial proposals for the use of non-stationary satellites, known as Non Geostationary Satellite Orbit( NGSO), for Fixed Satellite Services. In addition to the Fixed Satellite Service (FSS), there is also the Mobile Satellite Service( MSS) for mobile use.
