Patent ID: 8131212

Claim:
A controlled satellite link comprising a first link and a plurality of second links, comprising: a plurality of reference units located at respective ones of at least some of said second links, and configured for obtaining at least signal attenuation over said first link and said respective second link, and a control unit, associated with said plurality of reference units, configured for discriminating between first link attenuation and said respective second link attenuations and accordingly controlling at least one link transmission parameter associated with said first link and at least one transmission parameter respectively associated with each of said second links to dynamically adapt to changes in said obtained signal attenuation, and wherein said satellite link further comprises a derivation unit for deducting common attenuation and assigning said common attenuation at least in part to said first link and assigning differential attenuation to respective second links, thereby to adapt independently to changes in said measured attenuation at each respective second link.
