Use of TDM/PAMA satellite based communication as an option for the aeronautical communication

This paper deals with the multiple problems involved with the use of the VHF/ER in aeronautical communications, where multiple earth stations should operate simultaneously to communicate one ground based facility with a single airplane, and how a satellite communication operating TDM/PAMA may be the solution; in VHF/ER only one earth transmitter will effectively communicate with the airplane, the other stations will waste their time and energy.
