CAVU 2100® Multi-mode Digital Radio


The Exelis/Park Air Systems CAVU 2100® Multi-mode Digital Radio’s (MDR) many features accommodate increased traffic demands while maintaining air traffic safety.

The CAVU 2100 Multi-mode Digital Radio (MDR) uses proven commercial off-the-shelf (COTS) digital technology to combine reliability with the flexibility to meet the demands for new en route services.

The MDR is a Digital Signal Processing (DSP) based radio built on a modular hardware and software design. When operating in Amplitude Modulation (AM) voice mode, the MDR provides the same functionality as legacy systems. It is fully backward compatible with components such as remote controlled equipment, antenna transfer relays, voice switching and control systems. The MDR supports operation in both 25 kHz and 8.33 kHz AM modes.

The MDR provides full VHF Digital Link Mode 3 (VDL-3) digital communications per Radio Technical Commission for Aeronautics (RTCA) DO-224a, Minimum Aviation System Performance Standards (MASPS) and International Civil Aviation Organization (ICAO) Annex 10 to support an all digital National Airspace System (NAS).
