This paper presents an overview of the development of aeronautical satellite communi-cations over the past 30 years. The initial development of aeronautical satellite communications is de-scribed in the paper. The civil aviation growth and current unaccommodated communication systemsare discussed as well. The inherent shortcomings of present air-ground HF communications have hin-dered the development of civil aviation. but according to the Future Air Navigation Systems(FANS) concept aeronautical satellite communication-including Automatic Dependent Surveillance(ADS)-will be the key to eliminating the shortcomings of HF communication systems. Satellite-basedcommunication and surveillance will significantly improve air traffic control (ATC) over the oceanicand remote terrestrial airspace, and it will benefit civil aviation authorities, airlines as wel as passen-gers. This paper discusses the availability of system elements, and world wide trials, demonstrtionsand preoperational use of aeronautical satelli
