This document applies to earth terminals intended fornon-Government use in blanket-licensed Ka-band satellite networkswithin the United States of America. It also applies togeostationary space station transmissions used to provideblanket-licensed services to earth terminals within the U.S.A.
In such a network, a Network Control Facility (NCF) isresponsible for monitoring and controlling the transmit functionsof the earth terminals.
The earth terminals have the following characteristics:
• Earth terminals receive in the blanket-licensed bands withinthe Fixed Satellite Service (FSS) frequency range from 17.7 GHz to20.2 GHz.
• Earth terminals transmit in the blanket-licensed bandswithin the FSS frequency range from 27.5 GHz to 30.0 GHz.
• Earth terminals transmit and receive throughgeostationary satellites with spacing down to 2 degrees away fromany other geostationary satellite operating in the same frequencybands and covering the same area.
• Linear or circular polarization is used for transmissionand reception.
• The received and transmitted signals are digital innature.
• Earth terminal antenna aperture may be of anydimensions.
• Earth terminals are designed for unattendedoperations.
The earth terminal equipment considered comprises an outdoorunit, which is usually composed of the antenna subsystem andassociated RF electronics, and the indoor unit, which is usuallycomposed of receive logic, transmit logic, and modem, includingcables between these units.
This document applies to the earth terminal, its ancillaryequipment, and its various ports when operated within theoperational environmental limits declared by the manufacturer andwhen installed as required by the manufacturer by declaration or inthe user documentation.
All parts of the indoor unit related to reception, processing,and presentation of the received information, except for thecontrol channel, are outside the scope of this document. The syntaxof the control channel messages is outside the scope of thisdocument.
