MOBILE HYDROACOUSTIC BUOY-BEACON AND NAVIGATION EQUIPMENT METHOD OF SEA AREA Russian patent published in 2019 - IPC B63G5/00 B63G6/00 B63G9/00 B63G13/00 

FIELD: navigation systems.

SUBSTANCE: group of inventions relates to marine equipment for navigation equipment of sea areas and provision of safety of navigation, and determination of coordinates in sea of surface ships, boats, submarines and underwater vehicles. Mobile hydroacoustic buoys-beacon includes a current source, control equipment, a floating float with an antenna and a GLONASS satellite navigation receiver and equipment for receiving and emitting hydroacoustic signals. For naval navigation equipment, number of hydroacoustic buoys-beacons required for navigation equipment of preset sea area is calculated and points of their installation are determined. Hydroacoustic buoys-beacons are prepared on the basis for the installation, their operability is verified and loaded onto the watercraft. They are delivered to the specified sea area and in design points are dumped in water, after driving hydroacoustic buoys-beacons are transferred into working position. At the stationary buoys the anchor is separated, the buoy rope is unwound and installed on the ground, leaving the float with the antenna, as well as the drifting buoy, on the water surface, a radio station, a satellite navigation receiver, a set of satellite communication and sound underwater communication equipment are received, geographical coordinates of the buoy are obtained from the satellite navigation system and, on request of surface or submarine watercraft, they are transmitted over radio or underwater communication.

EFFECT: enabling the navigation equipment of the area to be accelerated and the work quality of its floating crafts in it to be improved owing to their accurate navigation parameters for performing maneuvers and improving safety of navigation.
