The S-404 new-generation on-board communications system is undergoing flight trials as part of Russia’s cutting-edge Kamov Ka-62 helicopter, a spokesman for Ruselectronics, part of the state hi-tech corporation Rostec, said at the HeliRussia exhibition on Friday.

"This is a fully digital new-generation communications system. It provides for pilots’ continuous communications with ground control posts through several channels and the constant reception of signals at an emergency frequency. The system independently controls its own work, adapting to the specifics and the characteristics of the signal received and actually ruling out the possibility of losing communications with the ground," the spokesman said.

The radio system is being developed by Polyot research and production association in Nizhny Novgorod in the Volga area, he said.

The antennae of various designations that are part of the system are built into the helicopter’s skin, which helps improve the communications quality and the chopper’s aerodynamic characteristics, the Ruselectronics representative said.

"The S-404 is based on the software-defined platform, which helps expand communications possibilities without changing the device’s hardware. For example, on the customer’s demand, a secure communications channel or a photo and video data transmission function can be added," he noted.
