Hydroacoustic warning station MG0767 (Amulet-P), hereinafter referred to as GASP, is designed to form directional acoustic radiation of high intensity within the allocated zone of the protected water area in order to:
a) to ensure underwater transmission of acoustic warning signals to underwater swimmers in all types of equipment approaching the protected object or penetrating into the protected zone of the water area;
b) ensuring transmission of speech signals (hydrograms) of the GASP operator, or automatic transmission of hydrograms from the GASP warning signals database;
c) provision of automated transmission in the mode of hydroacoustic telegraph and unmodulated hydroacoustic telephony of special warning signals of international standard about being in the restricted area for navigation;
d) voice warning of underwater swimmers about approaching the protected object or about violating the boundaries of the protected (prohibited) zones of the water area.
