ASELBUOY - Passive Directional Sonobuoy

ASELBUOY is a NATO-A size passive directional sonobuoy, deployed from patrol aircrafts and surface ships alike.

ASELBUOY can operate in two different depths (30m and 150m), providing directional acoustic information in the 5-2400Hz frequency band on the horizontal plane. The buoy can send this acoustic information to aircrafts and surface ships via one of its 96 VHF communication channels (136MHz-173.5MHz). Operating depth, VHF communication channel and operating time (0.5, 1, 2, 4 or 8 hrs) are programmable from the user interface on the buoy itself before deployment. As an expendable system, ASELBUOY scuttles at the end of its programmed operating time.
