The transceiver is implemented as a system of separate blocks, the combination of which makes it possible to achieve the optimum application configurable for any type of aircraft, helicopter or air traffic control unit. Its technical parameters meet ICAO regulations and NATO standards. With its characteristics and parameters, it is comparable with the transceivers used in the armies of NATO member states. It is often used for the modernisation of aircraft and helicopters manufactured in the Czech Republic or Russia.
