The radar incorporates both traditional RBS surveillance interrogation channel (modes 1, 2, 3/А, С) and separate surveillance channel – ADS-B 1090 ES thus combining customary MSSR and 4-channel ground station ADS-B 1090ES.
The ADS-B 1090 ES channel has a dedicated 4-sector antenna system and separate receivers that ensure surveillance of aircrafts with the antenna stopped or MSSR transmitter switched off during scheduled operations.. |
