SECURE DATALINK UNLOCKS FUTURE CAPACITY
This Solution was formerly part of PJ.14-02-01-W1
Reliable data is an essential building block of the European vision for the future communications infrastructure (FCI). Establishing secure communications between the ground and the air is vital to support the growth in traffic volume and complexity. 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 adoption of 4D trajectory management concepts for separation management will lead to more efficient flight paths, improved safety and fewer radio transmissions.
SESAR is looking at both avionics and ground infrastructure requirements for robust digital voice and data services. Among solutions under review, SESAR is researching multilink 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 L-band-digital aeronautical communication system (LDACS). This candidate solution will also address transversal topics and concepts, including the seamless transition from existing datalink technologies to LDACS and the provision of a ranging functionality in order to support navigation services as well.
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 datalink applications.
