Communication system having frequency reuse in non-blocking manner

A communication system for use with a system of geosynchronous satellites broadcasting a first beam at a first frequency, said geosynchronous satellites having a first position above a service area, comprising:

• a first stratospheric platform having a substantially fixed second position above a service area having a primary payload, said first stratospheric platform generating communication signals having the first frequency,
• a geographically fixed blocking area having a substantially fixed separation angle between said first position and second position less than a predetermined angle, said first stratospheric platform providing the communication signals to the service area outside the blocking area.
