FIELD: ocean engineering.;SUBSTANCE: invention relates to underwater engineering and in particular to techniques for creating navigation and control means for deep-water autonomous unmanned underwater vehicles (AUUV), capable of operating at maximum depths of the world ocean. In the method of navigation-information support of a deep-water autonomous unmanned underwater vehicle, a stationary bottom beacon is equipped with low-frequency (LF) hydroacoustic communication receiving-transmitting devices OS and AUUV, as well as high-frequency (HF) transceiving means of hydroacoustic communication with AUUV. Equipped with AUUV high-frequency hydroacoustic communication receiving-transmitting devices and hydroacoustic communication low-frequency receiving devices, as well as equipped with software for its on-board control system, implementing output AUUV to a stationary bottom beacon based on reception and processing of data received from a stationary bottomhole by hydroacoustic communication in the low-frequency range. Thereafter, the stationary bottom beacon is placed near the centre of the proposed area of operations. Starting point coordinates are set AUUV by their calculation based on ranging data of stationary bottom beacon based on receiving and processing data received from it in HF range of hydroacoustic communication. Enabling reception of onboard control commands AUUV from OS by receiving and processing data transmitted from OS in LF range and retransmitted by stationary bottom beacon in HF range of hydroacoustic communication. Providing telemetry data transmission from board AUUV by receiving and processing data received by stationary bottom beacon in high-frequency range and retransmitted to OS in LF-radioacoustic communication range. Working frequencies of hydroacoustic means of information exchange in LF-band is selected based on maximum removal condition OS from stationary bottom beacon, and working frequencies of hydroacoustic means of information exchange in HF-range are selected from condition of specified maximum removal AUUV from stationary bottom beacon required data transmission speed.;EFFECT: provision of navigation-information support AUUV, capable of operating at maximum depths of the world ocean, and reduced weight and dimensions and power consumption on board AUUV.;1 cl, 2 dwg
