Most of the switching
electronics is kept e.g.
camera base stations,
switcher main frame,
Satellite receivers, MW
link, DDA & most of the
patch panels.
Signal is routed through
MSR.
Signal can be Monitored
at various stages

 Earth Station is a very important part of
satellite communication system for
broadcasting of signals.
 It is an uplink center from which the
signals are fed to Satellite for distribution in

Station and received by many down link
centers inTV broad casting via PDA.
 TwoTypes:
 1) Analog
 2) Digital
 Digital Earth Stations are widely used
because of various advantages over analog.
