摘要： PURPOSE:To make possible the exact detection of a ship's position by making such prescribed calculation as to eliminate drawbacks by taking advantage of an inertia navigation method and GPS receiver. CONSTITUTION:A speed error calculation unit 12 compares the speed information from a speed display device 6 of the inertia navigation device A and the speed information from a GPS speed display device 10 and calculates the error thereof. A position error calculation unit 13 compares the position information from a position display device 7 of the device A and the position information from a GPS position display device 11 and calculates the error thereof. A karman filter 14 is incorporated therein with the ship model expressing mathematically the movement of the ship and takes out only the change-component of the course controllable by the rudder out of the signals inputted thereto. The output from the filter 14 is impressed to the auxiliary circuits provided respectively to the output side from an accelerometer 1 and the output side of a platform correction and calculation unit 5 to correct the respective signals.

摘要： PURPOSE:To make possible fully automatic measurement of position with high accuracy by combining pattern matching and point matching based on a specific target. CONSTITUTION:The reflection signal received by a radar scanner 1 is inputted to a radar signal processing unit 2 and is inputted to a signal processing unit 4 after the signal is subjected to coordinate conversion in a video signal converter 3. The signal is temporarily preserved in a storage device 5. On the other hand, a ship position recognizer 6 reads the electronic chart of the necessary sea area according to the present ship position and radar range out of an electronic chart storage device 7, transmits the chart in the unit 4 and stores the same in the device 5; at the same time the video signal and the electronic chart are superposed and matched and the correction rate of the ship position is transmitted to the recognizer 6 so as to be processed by the same. The fully automatic measurement of the position with high accuracy is thus made possible.

摘要： PURPOSE:To reduce the deviation of a ship from its waterway and to improve the safety, and to reduce the crew in charge of navigation by measuring the movement extent of the ship body under the influence of winds and waves and correcting the assumed value of the ship position by a feedforward method on the basis of the measured movement extent. CONSTITUTION:Data from sensors 200, etc., are collated with numeric models in memories 112 and 114; and a unit 102 calculates the movement extent of the hull due to wind pressure and a unit 104 calculates the movement extent of the hull due to a wave drift force. An arithmetic unit 106, on the other hand, estimates the ship position and a unit 108 measures the ship position. Then, a control signal output unit 110 makes a feedforward correction of the ship position assumed value inputted from the unit 106 on the basis of the movement extents of the ship body inputted from the units 102 and 104. A computing element 116 inputs the measured value of the ship position from the unit 108 and this is compared with the corrected value to obtain the error, which is inputted to a Karman filter 118. Its output is fed back to the unit 110 so that the control over a rudder and a screw machine 120 is in the optimum state.

摘要： PURPOSE:To judge the bottom clearance of a ship in a waterway peripheral sea area at a look by calculating the bottom clearance on the basis of the position of the ship, time, drift, depth of water, and tide level and displaying it in a different color. CONSTITUTION:An arithmetic unit 8 determines the sea area where the bottom clearance is displayed on the basis of the position of the ship detected by a rader 1. Then, the depth of water at a position in the display sea area among data on the depth of water stored in a water depth storage device 6 is read out together with the position, and the tide level which is at a position in the displayed sea area and at the time indicated by a timepiece 2 among tide level data stored in a tide level storage device 7 is read out together with the position. Further, the depth of water and tide level which are read out at every position are applied to calculate the depth of water at each position at every point of time indicated by the timepiece 2, and a larger draft values between draft values measured by draft meters 3 and 4 is subtracted from the depth of water at each current position to calculate the bottom clearance in the display sea area, and then the clearance is outputted on a CRT display device 9 together with its position.
