Abstract
Power spectral density in an aeronautical satellite communication system is controlled through the use of adaptive inroute selection and spreading. Once a communication session has been established between the aircraft and the satellite, environmental conditions and aircraft conditions are monitored to detect events capable of affecting transmit/receive properties during the communication session. A maximum allowable transmission output is determined based, at least in part, on governmental regulations and the conditions being monitored. One or more transmit parameters are adjusted in order to maintain transmission output power of the aircraft terminal below the maximum allowable transmission output power.
