A communication system and method are provided, wherein the system includes a first satellite orbiting in a first orbital path that communicates a first signal having a first content at a transmitting frequency while at a first elevation angle, and a second satellite orbiting in a second orbital path that communicates a second signal having a second content at the transmitting frequency while at a second elevation angle, wherein the first elevation angle is greater than the second elevation angle. The system further includes at least one terrestrial repeater that communicates a hierarchical modulated signal, wherein a hierarchical primary of the hierarchical modulated signal corresponds to the second signal communicated from the second satellite, and a hierarchical secondary of the hierarchical modulated signal corresponds to the first signal communicated from the first satellite, such that the first and second signals are communicated at the same transmitting frequency.
