Welcome to our LDACS website!

LDACS stands for L-band Digital Aeronautical Communications System. It is the upcoming air-to-ground communications standard and, therefore, an important data link technology within the future communications infrastructure for aviation. Standardization within ICAO (International Civil Aviation Organization) started in December 2016 and LDACS draft SARPs (Standards and Recommended Practices) have been developed and endorsed in October 2018.

This website gives a detailed overview on LDACS. You will find information about technical details for transmitter and receiver design, protocols, demonstrator implementations, and the extension of LDACS communications towards navigation. In addition, information and results from our LDACS flight trials are reported, which have been performed in March/April 2019. Updates on the LDACS standardization within ICAO are also made available.

Please feel free to download our LDACS White Paper.
