ActiveUS12650304B2Navigational route markingNavigational calculation instrumentsKaiman filterNon linear wave
Systems and methods for generating a phase-resolved ocean wave forecast with ensemble based data assimilation are disclosed. An example method includes receiving radar data corresponding to an ocean surface, and determining a surface elevation and a surface potential of a portion of the ocean surface. The example method also includes generating an ensemble of perturbed ocean surface data, and applying a phase-resolved nonlinear wave model to the ensemble of perturbed ocean surface data to generate a set of forecast ocean surface data. The example method also includes receiving a subsequent set of radar data corresponding to the ocean surface, and determining a subsequent surface elevation and surface potential of the portion of the ocean surface. The example method also includes combining, by applying an ensemble Kalman filter, the set of forecast ocean surface data with the subsequent surface elevation and surface potential to generate a phase-resolved ocean wave forecast.

System and method for dynamic navigation routing for inshore and nearshore coastal areas
PCT designated stageWO2026059787A1Navigational aids with satellite radio beacon positioningNavigational route markingData displayEngineering
A system and method of providing navigational routing paths through inshore and nearshore coastal areas that include surveyed depth information and visual indications of the suitability of such paths based on particulars of the user's boat and preferences are presented. Adjustments to both an indication of the depth and the suitability of each segment of the paths are provided. Manual input of local water level observations or tide data from local tide stations may be used for such adjustments. Adjustments may be applied locally or globally, and may be provided dynamically based on changing tide information over the travel time needed to reach distant segments along the navigational routing path. Such tide information is also used to adjust contour and depth area data displayed on bathymetric contour maps on which such navigational routing paths are displayed.

An autonomous cruising system is capable of discriminating a port sign and a starboard sign without depending on a position of a ship. The system includes processing circuitry that acquires an image generated by a camera installed in a ship. The processing circuitry identifies whether a mode of a lateral buoy included in the image is either a first mode or a second mode. The processing circuitry determines a country to which a position of the ship detected by a position detector belongs. The processing circuitry determines whether description of a sign of the lateral buoy is the port sign or the starboard sign, from the mode of the lateral buoy and the determined country, based on a given correspondence relationship indicative of whether each of the first mode and the second mode corresponds to either one of the port sign and the starboard sign in each country.
