Radio transceiver BURAN

for air traffic managementembedded

"BURAN" radio equipment is designed to provide information exchange (speech, data) of controllers of air traffic control systems, control posts and airports with crews of civil and state aircraft. Radio equipment is implemented on the principles of programmable digital radio (SDR) using touch panels for control and indication. The composition of the "BURAN" series includes: Radio station "BURAN-RST"; Radio transmitter "BURAN-PRD"; Radio «BURAN-PRM». Radio receivers "BURAN-PRM" have distinctive constructive features. One 19" case houses modules, providing 4 channels of radio reception. The touch control and display unit is common to all receivers. Simultaneous indication of the set reception frequencies is provided.
