Language in which you want to receive the document.


The present document applies to Earth Stations located on board Trains, which have the following characteristics. The EST may transmit and receive data when the train is in motion and also when the train is stationary. • The EST operates in a railway environment and, therefore, may be subject to occasional disturbances and interruptions in the satellite link. • The EST is operating as part of a satellite network (e.g. star, mesh or point-to-point) used for the distribution and/or exchange of information. • The EST is comprised of all the equipment, electrical and mechanical, from the antenna itself to the interface with other communications equipment on a train (usually referred to as the terrestrial interface). • The EST transmits on single carrier in the frequency range 14,00 GHz to 14,25 GHz, which is a portion of a band allocated to the Fixed Satellite Services (FSS) (Earth-to-space). • The EST receives in one or more frequencies within the range from 10,70 GHz to 12,75 GHz in bands allocated to the Fixed Satellite Services (FSS) (space-to-Earth) or the Broadcast Satellite Service (BSS) (space-to-Earth), depending on the ITU Region where the EST is located. • The EST uses linear or circular polarization. • The EST is designed to operate through a geostationary satellite (or a cluster of co-located geostationary satellites) that is at least 3° away from any other geostationary satellite operating in the same frequencies and over the same coverage area. • The EST transmits at elevations greater than or equal to 7° relative to the local horizon. • The EST is designed for unattended operation. • The EST is controlled and monitored by a Network Control Facility (NCF). The NCF is outside the scope of the present document.
