What is SADIS?
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.

Distributes World Area Forecast System (WAFS) products and global OPMET
Enables WAFC London to distribute data to more than 90 ICAO contracting states
Has coverage of around 60 per cent of the Earth's land surface
Two similar satellites located over the Atlantic and Pacific Oceans provide the complementary ISCS service, covering the remainder of the world. ISCS is operated by the United States
