Trunk Emergency SatcomVehicular Earth
Station
Function
and Use: The station type is a mobile satcom earth station,
supporting voice, image, data multi-media transmission. It has interfaces
to mobile communication base station Tx/Rx station (BTS), mobile
communication base station subsystem (BSS), and mobile service switching
center (MSC), and interfaces to terrestrial public telephone switching
network, supporting many types of protocol. Due to adopting digital
circuit magnifying equipment (DCME), communication capacity is greatly
increased and cost is decreased. The station type can be widely used to
trunk satcom, emergency TV broadcast, live TV relay, and emergency
situation. Composition: indoor equipment : image
codec, modem, up/down converter, DCME, antenna controller, antenna drive
equipment, beacon receiver, monitor unit, etc. outdoor equipment :
antenna, power amplifier, LNA, etc.
