International Communications Group has introduced an Iridium-based data transceiver designed for sending and receiving Acars (aircraft reporting and receiving system) messages and for Link 2000/Fans communications. When connected to an aircraft’s communications management unit, the DL-100 transceiver uses the short-burst data functionality of the Iridium satellite network to send Acars and other messages. Link 2000 and Fans1/A (future air navigation system) are datalinks that allow pilots and air traffic controllers to communicate via text message. The DL-100 unit can replace an existing high-frequency datalink or be used as an HF backup. An optional version of the DL-100 with a built-in GPS receiver provides automatic position reports.
