Satellite Data Link System

The Satellite Data Link System (SDLS) is a satellite-based radio communication system that will complement the currently used terrestrial one, as part of the overall Air Traffic Management (ATM) infrastructure. It will in particular allow, due to its geographical coverage extended also to remote locations, continuous aircraft position monitoring from the ground. It provides both voice and data communication services (via satellite and Ground Earth Stations) between on the one side, controllers and computers on the ground, and on the other, the aircraft's pilot and Flight Management System (FMS).
