On behalf of the International Civil Aviation Organization (ICAO), we have developed and operate SADIS.
These pages provide general information on the SADIS. Currently the acronym refers to Satellite Distribution System for Information Relating to Air Navigation. With the impending cessation of the satellite component of the service (SADIS 2G - see Important News item below), the acronym will refer to Secure Aviation Data Information Service with effect from 1 August 2016. A refresh of the SADIS webpages is planned for coming months, and in the meantime information relating to both services (SADIS 2G and Secure SADIS FTP) will continue to be provided.
SADIS is a high quality and cost-effective satellite data distribution system that brings vital flight information to aviation users around the world. It provides a point to multi-point service, via satellite in real-time, on a 24-hour basis.
