Abstract
A civil aviation communication system has a satellite subsystem including a constellation of satellites. A ground subsystem communicates with the satellite subsystem. The ground subsystem includes a number of networked ground stations at selected locations. An airborne communication subsystem is included in the aircraft. The airborne subsystem transmits to the satellite subsystem in a first frequency band. The airborne subsystem receives transmissions from the satellite subsystem in a second frequency band. The airborne subsystem communicates with a ground based system in a third frequency band. The third frequency band is between the first frequency band and the second frequency band.
