About LDACS1

Welcome to our LDACS1 website!

LDACS1 stands for L-band digital aeronautical communications system, type 1. It is the most promising and mature candidate for the future air-to-ground communications standard LDACS and, therefore, an important data link technology within the future communications infrastructure for aviation. LDACS1 is a broadband system based on OFDM modulation. It shares many technical features with 3G and 4G wireless communications systems.

This website gives a detailed overview on LDACS1. You will find information about technical details for transmitter and receiver design, protocols, demonstrator implementation, cell planning, and the extension of LDACS1 communications towards navigation.

The following video gives an introduction into the future communications infrastructure for aviation. This covers the “networking the sky” concept as well as LDACS1.
