Reliable datalink is an essential building block of the European vision for the future communication infrastructure (FCI). Establishing secure communication between the ground and the air is vital to support the growth in traffic
volume and complexity. In particular, the future operational concept of trajectory management in 4D – latitude, longitude, altitude and time – needs to be supported by a reliable, scalable, modular and efficient datalink technology. The objective is to enable the widespread adoption of 4D trajectory management concepts for separation management, which will lead to more efficient flight paths, improved safety and fewer radio
SESAR is looking at both avionics and ground infrastructure requirements for robust digital voice and data services. Among solutions under review, SESAR is researching multi-link technology in order to deliver higher data capacity, improved communications performance, lower transaction time and higher continuity.
Specifically, it is developing and standardising the candidate future terrestrial datalink system, called LDACS (L-band-Digital Aeronautical Communication System). The goal is to progress on the development and standardisation of LDACS technology, including the analysis of security concepts and the development of a
harmonized global standard. This solution will also address transversal topics and concepts, including the seamless transition from existing datalink technologies to LDACS and the inclusion of a ranging functionality.
The work is aligned with international standardisation activities at global level by agencies, such as ICAO, EUROCAE, RTCA and the Airlines Electronic Engineering Committee (AEEC), as well as ongoing research into future communications services capable of supporting a range of data link applications.
