Both spoken (voice) and data communications are done using the aircraft communication system. Communication between crew members and between crew members and ground staff is done through the aircraft’s communication system.
Additionally, it is utilised for ground stations, other aircraft, and communication with passengers (both speech and data). Currently, voice modulation of radio waves is the primary method of communication in aviation.
Data transfer, which can be accomplished without the use of human speech, appears to be the way of the future. However, voice communication is still essential for the safe flow of air traffic and will likely remain so for some time.
The Global aircraft satellite communication system market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
At NASA’s Glenn Research Centre, research and development efforts are concentrated on enhancing critical satellite communications technologies for aeronautical applications so that these technologies can be put into service as quickly as possible.
Advanced modulation, coding, and signal processing, high frequency phased array antennas, better antenna pointing and tracking algorithms, high speed fibre-optic signal distribution, modelling and simulation of terrestrial and satellite communication links, and analysis of communications and information infrastructure architectures are a few of the key technologies and research areas being pursued.
In order to assess and showcase these technologies, NASA Glenn has also created a Ku Band Mobile Aeronautical Satellite Communications Terminal and Testbed. The capacity of satellite communications to deliver sophisticated network connectivity suitable for the aviation communications environment has been first demonstrated by this terminal.
The International Civil Aviation Organisation created the Aeronautical Telecommunications Network (ATN) with the intention of offering ground-to-ground and air-to-ground data communications services to the aviation sector.
The seven-layer Open Systems Interconnection (OSI) paradigm serves as the foundation for ATN. It is a private network with unique addresses and a system for giving aeroplanes network mobility.
Their mobility approach relied on backbone routers updating network path information and a sizable address space. The related backbone router would send the routing information for that aircraft’s network back across the ATN backbone whenever an aircraft connected to a new access point. The ATN also has guidelines for controlling various QoS levels.
