Communication and ItNew generation of airborne radios are designed based on the SDR (Software Defined Radio) technology. Benefiting from the technology an appropriate infrastructure is provided for data transmission and establishing data link networks as well as improving technical specifications and stability in comparison with the old radios.
ARC-620 is a VHF/UHF airborne Software Defined Radio in a way that it can be substituted with the ARC-1400 old radio properly. This radio can be installed inside various jetfighters, cargos, and helicopters. Proportionate to the plane, there are several different remote control systems installed inside the cockpit to perform control commands remotely
