NETWORK TO MONITOR AREA OF WATER Russian patent published in 2013 - IPC G01V1/38 H04B11/00 

FIELD: instrument making.

SUBSTANCE: network to monitor area of water is made as capable of exchanging information with its external receiver, is formed by anchored hydroacoustic buoys, having positive buoyancy, equipped with a system of monitoring and control, facilities for fixation of monitored parameters of water environment and hydroacoustic modems. Hydroacoustic buoys are removed from each other at the distances that correspond to maximum permissible distance for this area for receive-transmit along a hydroacoustic channel. The monitoring and control system of each buoy is equipped with facilities to measure sound speed at various depth of the section of the area of water subject to monitoring, with the possibility to monitor depth of submersion of a buoy, which is equipped with facilities to change its location along the depth of the water area, at the same time each hydroacoustic buoy is installed as capable of information exchange along a hydroacoustic channel at least with one of buoys in the network, besides, at least one of the anchored hydroacoustic buoys of the network is made as capable of exchange along a radio channel with the external receiver of information.

EFFECT: increased actual distance of data transmission along a hydroacoustic communication channel.
