S-Band TDMA Data Link for ACMI & Virtual Radar

The DataLink is the main building block of leading manufactures of ACMI and Virtual Radar Systems in Trainer planes.


'Virtual Radar' system allows a Trainee Pilot to operate the full Avionics and weapon systems of a modern Aircraft on a Trainer plane. The system substitutes expensive hardware units such as multi mode Fire Control Radar (FCR), Radar Warning Receiver (RWR) and Identification Friend or Foe (IFF).  The Virtual Radar provides the pilot with an excellent scoring and debriefing ability by measuring and recording all his moves and actions through the aircraft Bus.




The BES' Data Link utilizes a sophisticated data communication system, it also allows for various target simulations, post flight debriefing  in three dimensions, as well as collision avoidance alert, an essential flight safety characteristic. 


Data Link for Virtual Radar Systems


Virtual Radar functionality can be introduced accurately in trainer planes that cannot accommodate real radar. The Virtual Radar is implemented with BES     Systems' multiple participant Airborne    S-Band TDMA data link with its 200-400 slots per second and data rate of up to 714KB/sec. The system enables any aircraft equipped with it to communicate with any number of other  participants without any ground or airborne master. Normally, with  an airborne omni directional antenna, the Data Link has a useful range of 60-70NM range. Using a ground station with high gain antennas it is possible to get ranges exceeding 120NM. The system includes three assemblies: A Data Link processor based on airworthy ATOM PC with a data link modem, a 45Watt FM  transceiver, and a Power Supply.
