Competitive analysis of current and upcoming satellite systems for ATM services

Satellites systems are a promising solution to cope with the capacity limitations of current air traffic control (ATC) systems. It is necessary to evaluate and assess existing and upcoming satellite systems taking into account air traffic management (ATM) requirements. This paper reviews a representative set of satellite communications (SatCom) systems and presents a competitive analysis based on objective criteria, to assess their suitability to support aeronautical services. Key drivers that should be considered for future systems design are identified and discussed. These key drivers are finally grouped to fulfil three complementary objectives that may not be possible to achieve through a single solution: improve service area, provide additional capability and capacity to existing terrestrial systems in high density airspace and to provide new services to passengers and airlines.
