METHOD FOR NAVIGATION EQUIPMENT OF MARINE AREA AND CONTROL OF ACOUSTIC OBJECTS IN IT Russian patent published in 2023 - IPC B63G5/00 B63G6/00 B63G9/00 

FIELD: navigation.

SUBSTANCE: methods for navigation equipment in marine areas, used to ensure the safety of navigation, as well as to monitor actions in the area of acoustic objects - underwater and surface craft. For navigation equipment in the sea area and control of actions in the area of acoustic objects, a mobile hydroacoustic floating beacon is used, entering a route assignment into its on-board control system and releasing it into the sea, immersing the mobile hydroacoustic floating beacon to a given depth upon arrival at the designated point, separating it from the floating beacon body with an antenna and lifting it to the surface by unwinding the cable connecting the float to the floating beacon body from the reel. A communication session between the floating beacon and a navigation satellite is established, navigation information is received from it and transmitted via cable to the beacon control equipment. Calculation in the computing device of the floating beacon of its true geographical coordinates based on the calculated data of the speed of horizontal movement and depth of immersion, measured by hydrodynamic and hydrostatic pressure sensors, switching the hydroacoustic floating beacon to the observation mode, which consists of listening to the surrounding space with the buoy's hydrophones. A controlled mobile sonar floating beacon is used; before laying it on the ground, an additional site with suitable soil quality is selected using a profiler. They provide the required mode of communication with the control point through an aviation or space repeater using a float with an antenna, which is raised to the surface or buried using a cable wound on a reel and its drive, and monitor the underwater space in observation mode with noise recording in a memory device, the control data is transferred to the control point during the next communication session; to relocate the controlled mobile hydroacoustic floating beacon, the buoy with hydrophones, as well as the cable with the float and antenna, are removed inside the housing.

EFFECT: monitoring the performance of equipment and remote monitoring of the underwater space.
