An aeronautical satellite communications system has now been operational for three years. Services are provided through four satellites in geostationary orbit and ten ground earth stations. Two types of avionics are in use: low-gain, for packet mode data, and high-gain for both packet mode data and circuit mode data and voice. The aeronautical satellite system operates in the L-band spectrum allocated by the ITU to AMS(R)S service. A hybrid system was selected using FDMA single channel per carrier (SCPC) for circuit mode and TDMA for system management and packet mode data. Packet mode data communications are based upon the OSI architecture. A 9.6 kbits/sec. voice coding algorithm is used for voice communications. The first aircraft was declared operation in October 1990, now more than 300 aircraft have been equipped with satellite communications equipment.
