L-band Digital Aeronautical Communications System (LDACS) - Technical Validations in SESAR2020

Long-term air traffic management (ATM) concepts for Europe and other regions with rapidly increasing number of aircraft movements require modern and performant mobile data links for safety-related air-ground communications. L-band Digital Aeronautical Communications System (LDACS) is one of the new technologies, which is tailored to the specific needs of the ATM community and developed in the Single European Sky ATM Research (SESAR) program. This paper illustrates results of the technical validations of LDACS carried-out in the SESAR2020 project “PJ.14 02 01 Future Communication Infrastructure (FCI) Terrestrial Data Link”, focusing on aspects related to LDACS physical layer and data link layer.
