Abstract: Systems and methods for automatic navigation of a marine environment area are detailed herein. A system for navigating a marine area includes a display, a processor, and a memory including a computer program code. The computer program code, when executed, causes, on the display, presentation of a chart including at least a portion of a body of water; receives an input of at least one condition parameter associated with the desired marine environment; determines a portion of the body of water defined by the at least one condition; and displays the determined portion on the chart. The computer program code further, when executed, determines a traversal coverage corresponding to a watercraft; and determines a route to traverse the determined portion based on the traversal coverage of the watercraft such that an entirety of the determined portion is covered by the determined traversal coverage of the watercraft during the route.

Abstract: Provided are a sonar system and transducer assembly for producing a 3D image of an underwater environment. The sonar system may include a housing having a transmit transducer that may transmit sonar pulses into the water. The system may include at least one sidescan transducer array in the housing that receives first and second sonar returns with first and second transducer elements and converts the first and second returns into first and second sonar return data. The first sidescan element may also transmit second sonar pulses, and at least one of the sidescan elements may receive the second sonar pulses to generate sidescan sonar return data. A sonar signal processor may then generate a 3D mesh data and sidescan image data and generate a 3D image data based on the 3D mesh data and sidescan image data. An associated method of using the sonar system is also provided.

Abstract: Provided are a method, apparatus, and computer program product for updating stored 3D mesh data from live 3D mesh data. The method may include processing, by a sonar signal processor, first sonar return data and second sonar return data from first and second transducer elements of at least one transducer array to generate live 3D mesh data. The method may include determining a position associated with the live 3D mesh data that corresponds to the position of the watercraft when the first sonar return data and the second sonar return data was received, and may include updating a stored 3D mesh data with at least a portion of the live 3D mesh data based on the position.
