Leonardo Interactive Digital Auco System (LEONiDAS)

LEONiDAS is an advanced, high performance audio and communications system designed for modeling and simulation. With LEONiDAS communication radios, intercom systems, voice alerting messages and navigation aids of an aircraft, helicopter or UAS can be easily simulated. An immersive audio environment can be also reproduced to recreate sound/noise perceived by the Trainee at the Cockpit.

LEONiDAS is used in Training Simulation to simulate Aural cues heard by the pilot inside the aircraft and to simulate Communications between Pilots, Instructors and Observers. In order to achieve the maximum quality locating the I/O audio interfaces nearest to the final sink/source, LEONiDAS hardware components are distributed among Cockpits, Instructor Stations and Server rooms.

Communication simulation include V/UHF Radio, SATCOM Radio, MIDS audio channels, role play Radios or Intercom, Warning message, Tones, seeker sounds, Voice Command recognition engines, text-to-speech, chatters. Radio includes electromagnetic propagation model that accounts for distance and terrain.

LEONiDAS toolbox includes components to control, debug the developed models including the capability to analyze audio signals in both time and frequency domains.

Communications support interoperability at LAN/WAN level for distributed training.
