Abstract:
A ground-station system comprising:a first ground station having:a first aerial for reception of a first satellite signal comprising an identification code and a destination code;a first processing arrangement having a first input, coupled to the first aerial, for reception and processing of the first satellite signal and having a first output for generation of a first outgoing signal; anda first detection arrangement, operative in conjunction with the first processing arrangement, for detecting the identification code; anda second ground station having:a second aerial for reception of a second satellite signal comprising an identification code;a second processing arrangement having a second input, coupled to the second aerial, for reception and processing of the second satellite signal and having a second output for generation of a second output signal; anda second detection arrangement, operative in conjunction with the second processing arrangement, for detecting the identification code; andwherein:the first detection arrangement comprises a first through-coupling arrangement for through-coupling the first aerial to the first processing arrangement in response to the identification code being a first type and for through-coupling the first aerial to a further second input of the second processing arrangement via a first link in response to the identification code being a second type; andthe first ground station further comprises:a further first detection arrangement for detecting the destination code; anda further first through-coupling arrangement, responsive to the further first detection arrangement, for through-coupling the first aerial to the first processing arrangement in response to the destination code being a first type and for through-coupling the first aerial to the further second input of the second processing arrangement via the first link in response to the destination code being a second type.
