摘要： The purpose of the present disclosure is to set the initial information of the anchoring object (target) of a ship with high accuracy. A ship navigation assistance system according to the present disclosure includes a provisional initial information specifier, a measurement sensor and processing circuitry. The provisional initial information specifier may accept a specification of provisional initial information for characteristic information on an object to which a ship anchors or docks (docks to a pier). The measurement sensor may acquire measurement information on an object using a ranging result of an area including the object.

摘要： An oscillation observation device includes a first receiver and processing circuitry. The first receiver is configured to measure carrier phases of positioning signal. The processing circuitry is configured to calculate a velocity of an object by using an amount of change in the carrier phases measured by the first receiver, and calculate an amount of oscillation of the object in a translational direction using the velocity.

摘要： A movement information calculating device includes a positioning sensor, a velocity sensor, an attitude sensor and processing circuitry. The positioning sensor is configured to calculate a position of the positioning sensor on a movable body. The velocity sensor is configured to calculate a velocity of the movable body. The attitude sensor is configured to calculate an attitude of the movable body. The processing circuitry is configured to calculate a center-of-gravity position and a center-of-gravity velocity of the movable body by using the position, the velocity, and the attitude, and calculate one of a turning center position and a pivoting position of the movable body by using the center-of-gravity position and the center-of-gravity velocity.

摘要： The purpose of the present disclosure is to suppress an error which occurs in movement, such as in anchoring a ship. A ship navigation assistance system includes a measurement sensor and a characteristic information updating module. The measurement sensor acquires measurement information on an object using a ranging result of an area including the object that is an anchorage target of a ship. The characteristic information updating module updates characteristic information on the object using initial characteristic information on the object or characteristic information before updating on the object, and the measurement information.

摘要： The present disclosure provides a learning data collecting system which is easy to collect learning data. The learning data collecting system includes a radar, a communication device, and processing circuitry. The radar receives a reflection wave of a radio wave transmitted around a ship and generates echo data associated with a direction. The communication device receives travel data of an other ship containing position data of the other ship. The processing circuitry extracts, from the echo data, partial echo data of an area corresponding to the position data.

摘要： Movement information is calculated with high accuracy, without being influenced by the number of GNSS signals receivable by each of a plurality of antennas. A movement information calculating device includes a plurality of antennas, a clock generator, a plurality of GNSS receivers, and an arithmetic logical unit. The plurality of antennas, each receives a GNSS signal. The clock generator generates a clock signal. The plurality of GNSS receivers are connected to the respective antennas, and share the clock signal from the clock generator and calculate GNSS observed values by using the shared clock signal and the GNSS signals, respectively. The arithmetic logical unit calculates movement information including a speed of a movable body based on the GNSS observed values from the plurality of GNSS receivers.
