The COFDM Base Station has been specifically developed for mobile reception of COFDM digital video transmissions from either aircraft or ground-based transmitters.
The Base Station Receiver System consists of three main parts:-
-ECS COFDM Active Switch Sector Antenna (MSA)
-ECS COFDM Base Station Briefcase Receiver
-ECS COFDM Portable Antenna Control Unit (ACU).
Global Navigation Satellite System (GNSS/GPS) information
is multiplexed onto the transport stream of the ECS COFDM
transmission and then decoded within the ECS COFDM Base
Station Receiver. The GNSS information is used to control the MSA. The MSA down-converts the RF signal to UHF to allow the MSA antenna to be situated up to 200 m away from the base station equipment.
