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.

• Uses an Intelsat 904 satellite located over the Indian Ocean
• 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
• Access to the internet-based SADIS FTP Service
• Highly cost-effective

The SADIS satellite uplink facility is located at the Cable & Wireless Communications hub at Whitehill Earth Station, near Oxford, UK.

The SADIS Gateway for OPMET is located at the National Air Traffic Services (NATS) Civil Aviation Communication Centre (CACC) at Swanwick, near Southampton, UK
