The BSN navigation timing unit is designed for telecommunication systems time synchronization via signals of satellite navigation systems GLONASS, GPS, GALILEO, QZSS within L1 band.
Time synchronization of telecommunication systems.
The BSN unit contains the МNP-М7 navigation receiver and the LNA-1 navigation antenna. Circuit boards are covered by radome.
